The Role of Artificial Intelligence in the Future of Façade Engineering: A New Era of Sustainability and Innovation
In today’s evolving world of construction, façades are no longer static components of a building. They have evolved into dynamic systems that serve multiple critical functions, from regulating temperature to conserving energy, and even enhancing indoor comfort. With sustainability becoming a top priority across the globe, façades are now at the forefront of innovation in architectural design. A significant factor driving this transformation is the integration of Artificial Intelligence (AI) into façade systems, which has the potential to revolutionize the way buildings interact with their environment.
THE GROWING IMPORTANCE OF FAÇADES IN SUSTAINABLE ARCHITECTURE
The building envelope, particularly the façades, plays a pivotal role in a building’s energy performance. A well-designed façade acts as a barrier, reducing energy consumption by
optimizing natural light, ventilation, and insulation. As urban areas expand and energy regulations become more stringent, there is a growing emphasis on designing façades that not only meet functional requirements but also contribute to energy efficiency and sustainability goals.
AI is emerging as a powerful tool in this context. By leveraging advanced algorithms and real-time data, AI can transform façades into intelligent systems capable of adapting to environmental conditions, optimizing energy performance, and providing occupants with personalized comfort.
AI-DRIVEN GENERATIVE DESIGN FOR OPTIMAL PERFORMANCE
One of the most promising applications of AI in façade engineering is the use of generative design algorithms. These algorithms can analyze a variety of factors, including local climate conditions, energy consumption targets, building
orientation, and material properties, to generate optimal façade designs. This approach allows architects and engineers to explore a vast number of design iterations, identifying solutions that offer the best balance between aesthetics, performance, and sustainability.
For example, AI-driven design tools can optimize the positioning and size of windows to maximize natural light while minimizing heat gain, reducing the need for artificial lighting and cooling systems. Similarly, AI can help identify materials that provide optimal thermal performance, reducing energy consumption for heating and cooling.
The ability to analyze complex datasets and generate multiple design options in a short amount of time allows architects and engineers to push the boundaries of façade design, resulting in innovative solutions that were previously unimaginable.
PREDICTIVE MAINTENANCE AND AIENABLED MONITORING
In addition to optimizing design, AI can also play a crucial role in the maintenance of façades. Predictive maintenance systems powered by AI use sensor data to monitor the performance of the building envelope in real time. By analyzing this data, AI can detect anomalies or early signs of deterioration, such as changes in temperature, humidity, or structural integrity. This allows building managers to address potential issues before they escalate, reducing maintenance costs and extending the lifespan of the façade.
For instance, sensors embedded in the façade can monitor thermal

performance and detect areas where insulation may be compromised. AI can then analyze this data to recommend targeted repairs or adjustments, ensuring that the building continues to operate efficiently.
This level of proactive maintenance not only enhances the longevity of the façade but also improves overall building performance by ensuring that energy efficiency is maintained over time.
ADAPTIVE FAÇADES: REAL-TIME RESPONSE TO ENVIRONMENTAL CONDITIONS
One of the most exciting developments in AI-driven façade engineering is the concept of adaptive façades. These façades are equipped with kinetic elements that can adjust in real time based on environmental conditions, such as sunlight, temperature, and wind speed. AI algorithms can control these elements to optimize the amount of natural light entering the building, regulate heat gain, and provide natural ventilation.
For example, an AI-controlled shading system can automatically adjust the position of louvers or blinds based on the position of the sun, ensuring that the building remains cool during peak sunlight hours while maximizing natural light during overcast periods. Similarly, AI can control ventilation systems to provide fresh air when needed, reducing the reliance on mechanical systems and improving indoor air quality.
The ability of adaptive façades to respond dynamically to changing conditions not only enhances occupant comfort but also reduces energy consumption, contributing to a more sustainable built environment.
THE CHALLENGES OF INTEGRATING AI INTO FAÇADE SYSTEMS
While the potential benefits of AIdriven façades are significant, several challenges must be addressed to ensure successful implementation. One of the primary challenges is the
need for robust sensor networks that can collect accurate, real-time data from the façade. These sensors must be reliable and capable of withstanding the harsh environmental conditions that façades are exposed to, such as extreme temperatures, moisture, and UV radiation.
Choosing the right AI model is another critical consideration. Supervised learning algorithms, which rely on historical data to predict future performance, are well-suited for tasks like energy optimization and predictive maintenance. However, reinforcement learning, which allows the system to learn and adapt based on ongoing feedback, may be more effective for controlling adaptive façade elements that need to respond in real time to changing conditions.
Cybersecurity is also a significant concern, as the integration of AI and IoT (Internet of Things) technologies into building systems introduces potential vulnerabilities. Ensuring that these
Façade Design
systems are protected from cyberattacks is essential to maintaining the integrity and safety of the building.
SUSTAINABILITY AND COMFORT: THE FUTURE OF INTELLIGENT FAÇADES
The integration of AI into façade systems has the potential to significantly improve both energy efficiency and occupant comfort. By connecting AI-driven façades to building management systems, it is possible to create a fully integrated system that adjusts elements such as shading, ventilation, and temperature based on occupancy levels and individual preferences.
For example, AI can be used to control the amount of natural light entering a building, reducing the need for artificial lighting and enhancing the well-being of occupants. AI can also optimize indoor temperatures based on real-time occupancy data, ensuring that heating or cooling is only provided when and where it is needed. This personalized approach to building management not

only improves comfort but also reduces energy waste, contributing to a more sustainable built environment.
CHALLENGES AND OPPORTUNITIES IN AI-DRIVEN FAÇADES
Despite the promising potential of AI in façade engineering, several challenges remain. One of the primary obstacles is the cost of integrating AI technologies into façade systems. The initial investment in sensors, AI algorithms, and building management integration can be high, making it difficult for some projects to justify the expense.
Data privacy is another concern, particularly when sensors are used to monitor occupancy levels and personal preferences. Ensuring that this data is collected and used in a way that respects privacy and complies with regulations will be essential as AI becomes more widespread in building systems.
Finally, the successful integration of AI into façade systems will require collaboration between architects, engineers, AI specialists, and building owners. The merging of traditional and new technologies will necessitate new skills and expertise, as well as a willingness to embrace innovative solutions.
A NEW ERA IN FAÇADE ENGINEERING
The integration of AI into façade systems represents a new era in façade engineering, building upon advancements in material science, construction methods, and computational design. AI-driven simulation tools will accelerate the design and analysis process, allowing architects and engineers to explore novel solutions that balance performance, aesthetics, and sustainability.
As AI continues to evolve, we will likely see the development of intelligent materials with features such as selfrepair, variable insulation, and even the ability to adapt to changing environmental conditions. The future of façade engineering is undoubtedly bright, with AI poised to play a key role in driving innovation and sustainability in the built environment.
By embracing AI-driven solutions, the industry can create façades that are not only more efficient and responsive but also more resilient and adaptable to the changing needs of the 21st century. As research and collaboration between disciplines continue, the widespread adoption of intelligent façades is becoming an increasingly realistic and exciting prospect.

The Evolution of Façades in India: A Study of Glazed Terracotta and ETFE Canopies
In India’s rapidly evolving architectural landscape, building façades have become a crucial element in shaping both the identity and performance of structures. Architects face the ongoing challenge of balancing aesthetic appeal, environmental sustainability, and cultural relevance—especially in a country as diverse and climatesensitive as India. Among the array of façade materials available today, two that have particularly stood out in our recent projects are glazed terracotta and Ethylene Tetrafluoroethylene (ETFE) canopies. These materials are notable for their unique blend of durability, versatility, and visual impact. In this article, I will explore how we integrated these materials into two of our recent projects in Bengaluru, highlighting their broader significance in the context of Indian architecture.
THE REVIVAL OF TERRACOTTA IN MODERN ARCHITECTURE
Terracotta, one of the oldest known building materials, has seen a resurgence in contemporary architecture, particularly in façade design. Its appeal in the Indian context lies in its natural warmth, earthy tones, and the connection it establishes with traditional vernacular architecture. In a
country where cultural heritage plays a significant role in design, terracotta offers a tangible link to the past while allowing for modern interpretations.
The terracotta used in today’s façades is far more advanced than the simple clay bricks of the past. Although terracotta is gaining traction in India, glazed terracotta remains relatively rare but holds immense potential. By applying a thin layer of glaze to terracotta tiles, architects can achieve a wide range of finishes—from glossy to matte, and from subtle monochromes to vibrant colours—each bringing a unique aesthetic to a building’s exterior. This glazing process not only elevates the material’s visual appeal but also significantly enhances its durability and resistance to weathering, making it an ideal choice for India’s diverse climatic conditions.

Façade Materials
The first project I’d like to highlight is an office complex in Bengaluru, designed for the Bagmane Group, where glazed terracotta plays a pivotal role in shaping the building’s character. Bengaluru, known for its moderate climate and status as India’s technology hub, offers unique opportunities for material innovation. Bagmane Memphis, part of the Bagmane Group’s Capital Masterplan in East Bengaluru, stands as the final piece of this masterplan. The building’s façade needed to be both visually striking and functional, embodying the city’s dynamism while offering a comfortable environment for its occupants. Additionally, it had to distinguish itself from the predominantly hard, curtainwalled structures in the surrounding area.
Central to the masterplan is a green park, which we designed to seamlessly integrate into and through the building. We conceptualized the two towers as a single mass, wrapped in a distinctive Case Study - 1

façade. This mass was then “pulled apart,” revealing a sleek, curtain-wall façade on the inner sides of the two towers.
Glazed terracotta in an antique green finish proved to be the ideal choice for this façade. The custom-made tiles in this distinctive shade not only create a unique aesthetic but also harmonize with the surrounding environment and central park. The antique green finish adds a contemporary flair, reflecting light differently throughout the day and giving the building a dynamic, almost kinetic appearance. This blend of tradition and modernity is central to the project’s concept, creating a structure that feels both rooted in its context and forwardlooking.
The thermal properties of terracotta were also a significant factor in our decision-
making. The material’s natural insulation helps regulate the building’s internal temperature, reducing the need for artificial cooling—a crucial consideration in Bengaluru’s climate. Additionally, the modular design of the façade allows for easy maintenance and replacement of individual tiles, ensuring the building’s longevity.
The office complex further integrates the terracotta façade with expansive
glass windows on the inner faces of the two towers, creating a dialogue between solid and transparent surfaces. This combination enhances natural light penetration while maintaining the building’s thermal efficiency. The result is a workspace that feels open and airy, yet grounded in the local architectural vernacular.

THE RISE OF ETFE IN INDIAN ARCHITECTURE
While terracotta connects us to the past, ETFE represents the cutting edge of modern architecture. Originally developed as a lightweight alternative to glass, ETFE has quickly become the material of choice for canopies and atrium roofs in some of the world’s most innovative buildings. Its high strengthto-weight ratio, combined with its transparency and flexibility, allows for large-span structures that would be impossible with traditional materials.
In India, ETFE is still relatively new, but its potential is enormous, particularly in the context of large public spaces where natural light and weather protection are paramount. The material’s ability to transmit up to 95% of natural light while offering superior UV protection makes it ideal for India’s sunny climate. Additionally, ETFE’s selfcleaning properties—thanks to its low friction surface—reduce maintenance costs, a significant advantage in a country where pollution can be a major concern.

Embassy NXT Bengaluru, India
The second project, where ETFE has proven to be a transformative material, is at Embassy NXT, a mixed-use development we designed for Embassy Group in Bengaluru. This masterplan includes a Hilton Hotel, a Hilton Garden Inn, a convention centre, and two office towers within Manyata Tech Park, a key business hub serving Bengaluru’s expanding international community. The hotels, designed to offer luxury and comfort, required a canopy that was not only functional but also iconic, serving as a focal point of the entire development.
The decision to use ETFE for this project was based on several key factors. First, the a need for a lightweight material that could span large areas without requiring heavy support structures. Traditional materials like glass were considered, but the structural impact was too great. ETFE, however, allowed us to create a
vast canopy at the hotel’s entrance that provides shelter while offering a grand, welcoming sense of arrival.
Second, ETFE’s transparency was vital for maintaining a connection between the indoor and outdoor spaces. The canopy allows natural light to flood the hotel’s entrance during the day, reducing the reliance on artificial lighting and creating
a bright, airy atmosphere. At night, the ETFE’s ability to be backlit turns the canopy into a glowing feature, enhancing the hotel’s visibility and presence within the urban landscape.
Initially, we encountered challenges with the perception of ETFE as an expensive and untested material in the Indian market, along with the complexities of

CONCLUSION: A NEW CHAPTER IN INDIAN ARCHITECTURE
As India rapidly urbanizes, the demand for innovative, sustainable, and culturally relevant architecture will only intensify. Materials like glazed terracotta and ETFE are poised to play a crucial role in this evolution, blending aesthetics with performance, and tradition with modernity. These materials offer unique opportunities to push the boundaries of façade design, allowing architects to create structures that are both contextually relevant and forward-looking.
Advances in glazing technology and fabrication techniques are likely to
expand the possibilities for glazed terracotta, enabling even more varied and customizable façades. Meanwhile, ETFE’s potential integration with smart technologies, such as photovoltaic cells and dynamic shading systems, will enhance its appeal as a material for the future.
Our recent projects have highlighted the transformative potential of these materials. In Bagmane Memphis, glazed terracotta bridged the past and present, creating a façade that is both visually striking and contextually appropriate. At Embassy NXT, ETFE provided the lightness and transparency needed to craft a space that is both functional and inspiring.
As Indian architecture continues to evolve, the thoughtful use of materials like glazed terracotta and ETFE will be key to creating buildings that meet today’s demands while resonating with tomorrow’s aspirations.

Better Design for Façade Safety - Key Points to Consider
In the dynamic realm of urban architecture, façade design stands as a cornerstone in the creation of successful and sustainable buildings. Often perceived primarily as an aesthetic element, the façade is, in fact, a critical component that significantly influences a building’s performance, user experience, and environmental footprint. In a diverse country like India, the considerations in designing façades are vast and complex, encompassing not only beauty but also functionality, high performance, and above all, safety. This article will explore six key design strategies that enhance façade safety, drawing insights from CCBA Designs’ projects and our in-house approach to innovative façade solutions.
1. CONTEXTUAL SENSITIVITY
Understanding and responding to the context is fundamental to any architectural project. In façade design, this means studying the site and creating a habitable environment that harmonizes with the local climate and cultural landscape. A well-considered façade should resonate with its surroundings, ensuring that the structure complements the existing architectural styles and heritage of the area. This approach fosters a sense of
place and belonging, embedding the built spaces within its environment rather than imposing upon it.
A prime example of contextual sensitivity is our project, the New Academic Block, CEPT University in Ahmedabad which draws from the local brick aesthetic and carefully addresses the region’s climate, with inset balconies and ample cross ventilation.
2. MATERIAL SELECTION AND DURABILITY
The choice of materials is a foundational aspect of façade design, influencing not only the building’s appearance but also its performance and longevity. Architects and designers must advocate for modern, ecological materials that contribute to
the building’s overall functionality and aesthetic appeal. Glass, for example, is increasingly popular in contemporary architecture, offering transparency and openness. However, it must be used judiciously to balance these qualities with energy efficiency and comfort. Glass blocks or tinted glasses are another great medium that helps to reduce heat gain.
In our Bajaj Brandview project in Pune, we employed a simple Zen-like cube design, utilising dark low-E glass and offsetting it with a transparent glass cylinder within a white steel structure. The façade, composed entirely of low-E double-glazed toughened glass with small horizontal ribs, exemplifies the importance of material selection. The use of the right glass—both in terms of type and placement—was crucial in achieving the desired aesthetic while enhancing the building’s thermal performance.
3. STRUCTURAL INTEGRITY
A façade must be more than just visually appealing; it must also be structurally sound. The design must account for various loads and forces, including wind, seismic activity, and thermal expansion. A notable example is the Kochi Refinery Headquarters in Kerala, where we designed a glass cylinder encapsulated with a Jaali system. This innovative façade cuts down on heat while allowing natural light to illuminate the interiors, significantly reducing energy consumption. The

4. PRIORITISING COMFORT AND SAFETY
Fire safety is a top priority in façade design. Façades are especially vulnerable during fire incidents, making the selection of fireresistant materials essential. By choosing materials with high fire-resistance ratings, buildings not only meet safety regulations but also protect occupants. In our project at Azim Premji University in Bengaluru, we utilised low-combustibility materials and incorporated fire breaks to prevent the spread of flames. This approach ensured that the building’s façade not only exceeded fire safety standards but also enhanced its durability.
In addition to fire safety, ensuring proper thermal and acoustic insulation is crucial in façade design. Good insulation makes the indoor environment more comfortable for occupants, improving both energy efficiency and productivity.
Another major risk to façades is water infiltration, which can lead to problems like material deterioration, mould, and even structural damage. To prevent this, façade designs should include practical elements like overhangs, ledges, and drainage channels. These features not only protect the building from water
damage but also add to the structure’s visual appeal, blending functionality with aesthetics.
5. LIFECYCLE MANAGEMENT FOR FAÇADES
Rapid urbanisation and population growth in Indian cities have led to a surge in high-rise buildings and infrastructure
projects. As these structures age, proper façade maintenance becomes crucial to ensure safety and prevent deterioration.
To truly ensure the long-term safety of building façades, a comprehensive approach to risk assessment must be developed—one that carefully evaluates hazards, vulnerabilities, and public exposure. Hazards refer to the likelihood of natural or external events, such as extreme weather or seismic activity, affecting the structure. Vulnerability, meanwhile, is the susceptibility of the façade’s elements to damage, often influenced by their current condition and maintenance history. Exposure accounts for the extent
to which people, property, and adjacent structures are impacted by these events. The combination of these three factors offers a holistic view of potential risks, encompassing everything from gradual degradation to sudden loss of functionality, damage to nearby elements, and the most crucial factor— the safety of building occupants.

Façade Safety
Over the past four decades, the concept of building maintenance has evolved dramatically, fueled by innovations in digital technology and management practices. What was once a reactive process has shifted towards a more proactive and predictive model. New methodologies like Life Cycle Costing (LCC) have come to the forefront, allowing architects, engineers, and building managers to assess the total cost of a façade—not just at the design and construction stages, but throughout its entire life span. This method takes into account uncertainties, such as unforeseen failures or material deterioration, and emphasises the importance of maintaining a façade as part of a larger, ongoing strategy rather than a one-time fix.
Façade maintenance is not just a technical requirement but a responsibility that touches on public safety, urban health, and the overall sustainability of our built environment. As technology advances, the integration of artificial intelligence into risk assessments promises to revolutionise this process, making it possible to evaluate the operational condition of façades in real time and anticipate issues before they arise. By focusing on the long-term care of façades, we can ensure that our country’s urban infrastructure remains safe, efficient, and resilient.
6. SUSTAINABILITY AND ENVIRONMENTAL IMPACT
A sustainable façade considers its environmental impact at every stage, from material selection to energy performance. Sustainable design practices contribute not only to the health of the planet but also to the safety and well-being of building occupants, making them an essential consideration in modern architecture.
One of our most notable projects in this regard is Suzlon One Earth Global Corporate Headquarters , a building that achieved both LEED Platinum and TERI GRIHA 5 Star certifications. The façade incorporates shading devices like louvres and overhangs, reducing heat gain and glare while allowing for natural ventilation and daylight penetration. These features significantly enhance the building’s energy efficiency, with 8% of its annual energy generated onsite through photovoltaic panels and windmills.
Ensuring the safety, functionality, and sustainability of a building’s façade is about more than just meeting regulatory requirements. It’s about creating environments that are safe, sustainable, and conducive to the well-being of all who interact with them. At CCBA Designs, our approach ensures that each project is tailored to its specific site conditions, optimising the building’s performance and minimising its environmental impact. By considering the factors discussed above, we can create façades that are not only beautiful but are also highperforming and safe, contributing to a more sustainable and resilient built environment for India.

Sustainable Design for Safe Buildings: Balancing Environmental & Safety Considerations
Sustainable design for safe buildings represents the way we conceptualise and construct our built environments. By integrating environmental considerations with safety protocols throughout the project lifecycle, we can create buildings that not only reduce environmental impact but also prioritise the well-being and safety of occupants. Through collaborative partnerships amongst Property Management (PM) companies that offer project management consultancy (PMC), architectural solutions and construction advisory, one can build innovative design solutions.
THE IMPORTANCE OF SAFETY IN SUSTAINABLE DESIGN
Safety is non-negotiable in building design. A sustainable building must not only minimise its environmental impact but also provide a safe and secure environment for its occupants. Ideally, a safe building should seamlessly integrate into natural cycles. This can be achieved by incorporating safety features such as enhanced daylighting to reduce eye strain and promote health, adaptive thermal comfort systems, biodiversity promotion, microclimate optimisation,
and building envelope enhancements. Additionally, the building should provide adequate access and egress routes to accommodate diverse occupants, include a fire command centre, and designate refuge areas to ensure the safety and well-being of occupants in case of emergencies.
CHALLENGES IN BALANCING SUSTAINABILITY AND SAFETY
Sustainable design principles often raise concerns about compromised safety standards. For instance, optimising natural ventilation to reduce reliance on mechanical systems may impact fire safety measures or indoor air quality. Similarly, the use of innovative materials and construction techniques, although environmentally friendly, may pose unforeseen hazards if not adequately tested and regulated.
THE RISE OF SUSTAINABLE DESIGN
In recent years, there has been a significant shift towards sustainable design practices in the construction industry. Architects, engineers, and developers are increasingly incorporating green building principles to reduce energy consumption, minimise waste, and lower the carbon footprint of buildings. From passive design strategies to the integration of renewable energy systems, sustainability has become a driving force in shaping the built environment.

Constructing Safer External Cladding Façade Systems
Why we can’t forget about cavity barriers
External cladding façade systems— both ventilated and nonventilated types— are becoming an increasingly popular choice for building exteriors in many parts of India and beyond, thanks to their energy efficiency benefits and wide aesthetic possibilities. However, the air gap between the inner and outer finishes of these ‘double wall’ constructions presents a very serious fire risk if not carefully considered, especially in densely populated cities like Mumbai where high-rise residential buildings are becoming commonplace.
Whilst there is much focus on passive fire protection in curtain walling applications, and on material reaction to fire in cladding applications – cavity barriers for preventing the unseen spread of fire and smoke within the concealed space of both ventilated and unventilated external cladding systems are currently and frequently overlooked by designers, specifiers and authorities alike.
MIND THE GAP
Ventilated façade systems typically consist of a backing wall or an inner concrete structural element, potentially an insulation layer, waterproofing layers, brackets, and
then the external cladding finish, which can be made from a range of attractive materials from aluminium cassette panels to masonry slips. Separating the inner wall from the outer skin is an air gap. Also referred to as a cavity, this space allows any moisture that enters the façade system due to rainfall or humidity to (depending on the system design i.e. ventilated and drained or pressure equalised) either effectively drain or vent away, or limit water penetration, preventing condensation, corrosion and mould growth.
Additionally, due to the air pressure differential between the bottom and top of the cavity, this gap allows a continuous cycle of air to flow through the cavity from top to bottom. This helps to cool down the exterior of the building, supporting comfortable temperatures indoors without over-reliance on potentially costly mechanical air conditioning — making them a sensible choice for projects aiming for lower operational costs and higher sustainability credentials.
Cavity barriers should be appropriately specified for the type of system they will be installed in, and climate zone factors should be taken into consideration
Cavity barriers are fundamental to the fire safety of buildings with external cladding façade systems
Non-ventilated cladding systems are similar in construction to ventilated façades in that they have a cavity; however, they are not engineered to expel moisture which can be particularly problematic with India’s rising relative humidity levels in both day and night.
However, regardless of the system type, in the event of a fire entering the external wall construction, this cavity can pose a real challenge to the building’s fire safety as it draws heat, smoke and flames up the building, affecting multiple floors and putting many lives at risk. Even the smallest fire within the cavity can quickly become ferocious as the confined space means any radiant heat is trapped and can only travel upwards, creating a hotter fire that can easily spread.
To prevent this, the cavity needs to be closed off using cavity barriers— blocks of fire-resistant material which seal the cavity in strategic locations, such as at junctions between walls and floors and around windows and doors, to subdivide the cavity into smaller voids creating compartments that contain the fire into an area of manageable risk until it can be fully extinguished. This prevents extensive fire spread, allowing occupants enough time to escape, fire and rescue services to perform their operations, and limiting property and asset damage.
CAVITY BARRIER OPTIONS
Standard cavity barriers are ‘full fill’ or ‘closed state’ products, meaning they
are fitted directly between the internal and external layers to completely seal the cavity. This makes them ideal for vertical applications in both ventilated and non-ventilated systems as they can help maintain the air pressure within compartments, preventing the fire from spreading horizontally around the building.
They are also used in a horizontal orientation for non-ventilated systems, inhibiting fire and smoke from spreading vertically. Whilst ideal for dry climates, in high-humidity regions these closed-state systems can result in condensation forming within the cavity, leading to moisture buildup on the cavity barrier and dampness within the building envelope. Similarly, in ventilated façades, this orientation means that they would prevent the system from effectively ventilating or draining away water leading to the same problems.
To resolve this issue with ventilated systems, ‘open state’ cavity barriers were developed. These include an integral intumescent material that rapidly expands in reaction to high heat (around 130°C). This allows them to be fixed to the internal wall, leaving the ventilation gap open to allow for free vertical movement of air and moisture drainage day-to-day (sometimes referred to as the ‘cold state’). However, in the event of a fire, the intumescent expands in a matter of seconds until the void is fully closed and a robust fire seal is formed.
CAVITY BARRIER REQUIREMENTS
Despite being fundamental to the safety of external cladding systems, currently, and surprisingly, there are no regulatory requirements for cavity barriers in India. However, many regions around the world do mandate their use, such as in the UK and the UAE, and there are an increasing number of building owners, investors and insurers from such places asking for cavity barriers to be installed on their Indian properties. Whilst it is likely that guidance will change in the future, architects and façade designers do not have to wait. Both testing and real-world fires demonstrate that cavity barriers can make a significant contribution to the overall passive fire safety of a building, whilst selecting cladding and cavity barrier systems that are appropriate for the climate conditions can help avert moisture-related issues.
CAVITY BARRIER TESTING
However, to specify them correctly, it is important to understand what fire test standards to look out for. Standard fullfill cavity barriers can be tested to EN 1366-4 Fire resistance tests for service installations - Part 4: Linear joint seals. This standard determines the fire resistance of linear joint seals. It tests both horizontal and vertical applications and allows some movement in one direction before the test starts.
However, there is understandably some difficulty using the standardised tests to determine the performance of open state cavity barriers, as the time taken
The use of cavity barriers for compartmentation in ventilated and non-ventilated cladding façade systems should be standard practice
Façade Safety
for the gap to close would initially lead to a technical ‘fail’, even though as soon as the intumescent has activated, fire integrity and insulation are established. To help resolve this issue, the UK’s Association for Specialist Fire Protection (ASFP) produced a Technical Guidance Document, TGD 19. This outlines the test configurations and failure criteria for the testing of open-state cavity barriers and the pending prEN 1364-6 standard which is being developed specifically for cavity barriers. The test is based on the existing EN 1366-4 linear joint seal test (using the principles of EN 1363-1) but modified with upstands to better replicate the cavity construction and allows 5 minutes for the intumescent to close the gap.
Whilst these tests can determine standalone cavity barrier performance and therefore general suitability for the purpose it is marketed for, it is only through large-scale testing that we can fully understand how complete assemblies perform in their intended application and how they might perform in a real-life fire scenario. Such testing examines all the system components together, providing data on how the different products interact, along with the impact of details such as joints, gaps, and penetrations on the overall fire performance. Therefore, data from large-scale systems tests such as BS 8414-1 &2 and NFPA 285 that evaluate the performance of a complete façade assembly can be invaluable when considering cavity barriers.
It is important to note that, even with the inclusion of cavity barriers, systems can fail if the external cladding allows the fire to spread up the outside of the building causing the panels to move, break down or come away. Any malfunction with the cladding would likely leave a path for the flames to spread up and over the cavity barrier and up the cavity. Therefore, it is vital to always refer to the latest specialist advice for façade design and specification, and to ensure high-quality workmanship at every stage.
FAÇADES FOR THE FUTURE
External cladding façade systems bring both a wealth of creative potential and clear thermal efficiency benefits to all kinds of buildings. Ensuring that they include cavity barriers that have not only been appropriately specified for the type of system they will be installed in, and that climate zone factors have been taken into consideration, but that their performance is backed by testing that reflects their end use can help to protect India’s built environment for generations to come.

Fire Resistance of Perimeter Fire Barrier Joint Systems
Understanding Codes and Standards, Selecting the Right System, and Navigating Common Pitfalls
Fire safety is a critical aspect often overlooked by building owners and occupants alike. While many assume that buildings are inherently designed with fire safety in mind and that codes are meticulously followed, one frequently neglected area is the gap between an exterior curtain wall and the floor’s edge. This significant fire safety risk can be effectively mitigated by installing a perimeter fire barrier
The United Nations projects that within the next two decades, about 51% of India’s population will reside in urban areas. This trend, coupled with existing urban pressures, is likely to increase the Floor Space Index (FSI). Rapid urbanisation demands the swift adoption of advanced technologies and faster construction methods. In the last ten years, high-rise buildings have increasingly embraced curtain wall glazing systems, prized for their design
flexibility, visual appeal, and energy efficiency. However, these innovations also bring inherent fire safety risks that warrant careful consideration and thorough examination.
When designing and constructing curtain wall systems, adhering to building regulations and national or international testing standards is crucial for fire safety performance. Neglecting or compromising on the design and
testing of these systems, especially at the slab opening’s edge, can have severe consequences.
A crucial element in mitigating fire risks is the use of Perimeter Fire Barriers (PFBs). Mandated by various national and international building codes, PFBs effectively inhibit the spread of fire and smoke between floors.
The “chimney effect” and “leap-frog effect” enable fire to spread quickly between floors at a building’s perimeter, emphasising the importance of welldesigned, properly installed, and regularly maintained perimeter fire barrier systems. The varying gap between the slab edge and curtain wall, particularly in concrete structures with construction tolerances, highlights the vital role of building codes and standards. These guidelines stress the need for perimeter fire barriers and offer methods to safeguard the space between fire-rated floors and exterior walls, effectively controlling fire and smoke spread across floors.
CODES AND STANDARDS:
NBC 2016, Clause 3.4.10.2 (b) mandates that all gaps between floor slabs and façade assemblies be sealed at every level with fire-resistant materials matching the floor slab’s fire rating. This crucial measure prevents fire and smoke from spreading between floors.
In accordance with IS-18190, building codes mandate that all gaps between floor slabs and façade assemblies be sealed at every level with fire-resistant materials matching the floor slab’s fire rating. This crucial measure prevents fire and smoke from spreading between floors. The standard outlines fire resistance testing methods for evaluating perimeter
firestop assemblies, drawing significant input from ASTM E2307 and UL 2079.
Assembly Testing: IS 18190 specifies a test setup using a two-story building with the ground floor subjected to a post-flashover fire. The test employs two burners—one inside and one outside— to generate a flame plume along the building’s side. An exterior curtain wall is installed on one side, with fire-resistant materials filling the gap between the curtain wall and the floor slab edge. This testing evaluates the assembly’s ‘F-Rating’ (Fire Rating), ‘T-Rating’ (Insulation Rating), and ‘L-Rating’ (Smoke Rating).
TEST SEQUENCE (IN ACCORDANCE WITH IS 18190 AND ASTM E2307):
Cycling Test: Perimeter joint systems undergo testing to ensure they can withstand live loads and environmental forces such as wind, thermal, and seismic impacts. This test demonstrates the compatibility of joint system components with the supporting construction. It subjects the joints to 500 or 100 complete movement cycles at a rate of 1 to 10 or 30 cycles per minute before the fire test.
Fire Test: This test evaluates the performance of the perimeter fire barrier by observing the behavior of fire and hot
Fire Safety
gases on the unexposed side of the barrier and any adjacent supporting structures.
Smoke Rating: IS-18190 also requires evaluating the L-Rating for smoke containment, in addition to assessing fire performance. Fire-resistant joint systems protecting joints in smoke barriers and perimeter fire containment systems shielding voids at the intersection of a horizontal smoke barrier and an external curtain wall must undergo air leakage testing according to UL 2079. The L-Rating should not exceed 5 cubic feet per minute per linear foot (0.00775 m³/s m) of joint at 0.30 inches (74.7 Pa) of water, for both ambient and elevated temperature tests.
SELECTION OF THE RIGHT SYSTEM:
Unlike some fire safety elements that primarily require design and specification, perimeter fire barrier systems demand meticulous attention to design, specification, and installation. This necessitates close collaboration among the architect, specifier, and general contractor to ensure proper implementation of each system component.
SOME OF THE COMMONLY SEEN CURTAIN WALL ARRANGEMENTS THAT INFLUENCE THE PERIMETER FIRE BARRIER SYSTEMS’ PERFORMANCE IN FIRE:
Selecting the right system requires understanding key application details, including: • Exterior wall composition (e.g.,
steel studs, aluminum mullions) • Spandrel glass and backpan material • Curtain wall insulation • Gap width • Hourly rating (F-Rating) • Smoke rating (L-Rating) • Joint width • Movement requirements (static or dynamic)
NAVIGATING COMMON PITFALLS IN PERIMETER FIRE BARRIER SYSTEMS
Edge-of-Slab Joints: Deviations from tested construction specifications in curtain wall systems can compromise fire safety. It’s crucial to adhere strictly to firestop system requirements, ensuring the installation matches the tested system precisely. For example, transom heights—measured from the floor to the bottom of the vision glass—must conform to firestop system specifications. Transoms placed closer to the floor than allowed by the tested system can lead to failures. Low transom heights may cause higher temperatures, potentially igniting sealants and resulting in premature fire spread. Design choices that prioritise aesthetics over fire safety can create significant conflicts. To avoid these issues, effective coordination between design professionals and strict adherence to firestop requirements are essential.
Curtain Wall Insulation and Joints:
Continuous insulation between mullions is often essential. Vertical seams in the insulation must be firmly secured to prevent gaps that could allow fire or smoke to spread. Maintaining the integrity of mineral wool insulation is crucial for effective firestopping. This may require
Fire Safety
reinforcing components like welded pins or Z-clips, as specified in firestop systems. Poor securement can result in insulation failure, compromising the entire system’s effectiveness.
Reinforcing Steel: For systems using non-stone or non-concrete panels, 20–22 gauge steel angles are often crucial for maintaining stability, as fire can cause aluminum components to soften. These steel angles, when specified in firestop systems, must be installed during construction. Adding them after construction can be impractical and expensive, underscoring the importance
of early coordination in curtain wall design.
Impaling Pins and Z-Clips: Proper function of perimeter firestop systems hinges on keeping insulation in place. Mechanical fasteners—such as impaling pins or Z-clips—are crucial for preventing insulation shifts during fires. Neglecting these fasteners can lead to insulation falling out, compromising fire resistance. Past incidents of inadequate securement have resulted in increased fire spread, highlighting the critical need to follow installation requirements precisely.
Improper Mineral Wool Installation: Install mineral wool with fibers running parallel to the curtain wall studs. Horizontal installation can compromise the wool’s compressive properties and reduce fire resistance. Proper installation is crucial for maintaining the integrity of firestop systems.
Selecting the Right System: Choose the appropriate perimeter firestop system by consulting third-party certification laboratory directories. UL and Intertek listings offer comprehensive insights into fire containment systems. These directories employ specific nomenclature to identify various firestop systems, aiding in the selection of the right system for your project’s needs.
Engineering Judgments
(EJs): Informative Annex A of IS-18190 outlines detailed guidelines for Engineering Judgments (EJs). When on-site conditions deviate from the original design or unexpected construction challenges occur, EJs provide alternative methods to preserve the firestop system’s integrity. As redesigning may be impractical, these alternative recommendations must align with the original fire-tested designs. Skilled professionals should formulate EJs following International Firestop Council (IFC) standards and sound engineering principles.
Installation: Firestop manufacturers typically offer specific programs and qualification criteria for installers, providing education and training on trade-specific installation methods. As perimeter fire barrier systems are “Listed” systems, they must be installed in accordance with their listing and the manufacturer’s instructions. To ensure the effective functioning of the perimeter fire barrier system, follow this 5-step approach:
1. Rating compatibility: Verify that the perimeter fire barrier system’s rating meets or exceeds the adjacent floor’s rating.
2. Accredited testing and listing: Confirm that an accredited laboratory has tested and listed the Edge of Slab (EOS) joint system.
Zero Spandrel / Pseudo Spandrel
Spandrel with Backpan
Ensure the field installation aligns with listing specifications for gap width, curtain wall spandrel insulation (type, thickness, density), and safing insulation (type, depth, % compression).
3. Engineering judgments (EJs): If a tested system matching site conditions is unavailable, obtain an Engineering Judgment from the manufacturer.
4. Installer qualifications: Ensure a trained and qualified installer performs the installation.
5. Documentation: Thoroughly document the installed system to facilitate future inspections and maintenance.
By addressing these key aspects, you ensure proper installation and ongoing compliance with safety standards.
CONCLUSION
The effectiveness of the Fire Barrier System hinges on its correct design, installation, inspection, documentation, and maintenance. Each assembly must display a clearly visible design listing and approval label that matches the construction type, joint gap specifications, and required fire, smoke, and movement ratings.
Product manufacturers or suppliers are responsible for providing comprehensive submittals. These should include system design listings or test certifications from accredited laboratories, complete with illustrations and adherence to applicable standards for each system configuration.
Rigorous compliance with code requirements not only ensures safety but also instills confidence in builders, contractors, architects, inspectors, and occupants. This commitment creates a secure environment and supports firefighters in their rescue and firefighting efforts—ultimately saving lives and safeguarding valuable assets.

Fire Resistance Tests Across Various Standards - Similarities and Differences: An Experimental Study
Fire safety is a critical concern in the design and construction of buildings, influencing both the selection of materials and the engineering of structural and functional elements. Among the many strategies for mitigating fire risks, implementing rigorous fire test standards is paramount. These standards serve as benchmarks to evaluate the fire resistance of building components, ensuring that they can withstand fire for a designated period, thereby allowing safe evacuation and minimising structural damage.
However, the landscape of fire test standards is far from uniform. Different countries and regions have developed their own methodologies and criteria for assessing fire resistance, reflecting variations in building practices, regulatory environments, and fire safety philosophies. These differences can
have significant implications for global trade, construction practices, and safety regulations.
This article aims to explore the differences in fire resistance test standards across various jurisdictions. By examining the methodologies, criteria, and outcomes associated with these standards. We have compared ASTME119 to ISO834-1 in this article. UL standards and ASTM standards have almost the same resistance to fire test curves and instrumentation. ISO 8341 has the same instrumentation as per IS/ISO 834-1 and EN 1363-1 standards. BS 476-20 and AS 1530-4 standards have the same curve but different instruments.
DIFFERENCES IN THE TIME TEMPERATURE CURVE:
When planning for fire resistance testing using a cellulosic curve, it is important to note that the cellulosic curves in American standards differ from those in other international standards. In the ASTM E119 and UL standards, the cellulosic curve is not expressed as a formula; instead, it is presented in a tabular format with the temperature setpoints at 5-minute
Graph 1: Comparison of standard time temperature data in ASTM E119 and ISO 834 in its first 10 minutes
Graph 2: Comparison of standard time temperature data in ASTM E119 v/s ISO 834 in 4 hours
intervals. This allowed testing laboratories more flexibility in manually adjusting the temperature of the furnace. However, with the emergence of modern control systems, it is possible to accurately control the furnace temperature every second.
Standards like BS 476-20, EN 1363-1, ISO/ IS 834-1, and AS1530-4 provide the timetemperature curve using an equation: T=345 log10(8t+1)+20, where, T is the furnace temperature at the time t in °C, and t is time into the test, measured from the ignition of the furnace, in minutes. Because this curve is equation-based, it can generate data every second, enabling precise furnace control.
Upon analysing the time-temperature data, noticeable temperature variations between American standards and other international standards are evident. These differences are outlined in Table 1 and illustrated in the accompanying graph below.
DIFFERENCE IN INSTRUMENTATION:
When comparing ASTME119, BS47620, EN 1363-1, IS/ISO-834 part 1, and
AS1530-4 test standards, differences in instrumentation become apparent, particularly in the method of temperature measurement using K-type thermocouples. Each standard employs different practices for positioning the thermocouple junction in relation to the heat source. This variation in thermocouple assembly not only affects how the furnace is controlled but also significantly impacts the specimen’s exposure to heat, despite using the same time-temperature curve. This is due to the varying time constants of the different thermocouple assemblies. Refer to Figures 1, 2, and 3.
UL/ASTME119:
In ASTM E119/UL263 and other UL standards, K-type thermocouples with 16-to-18-gauge wire are enclosed within an Inconel tube. Temperature measurement involves the heat passing through a 2.79mm thick layer of steel alloy and an air gap, before reaching the measuring tip of the thermocouple. This setup results in a slower response time for the thermocouple, potentially increasing the sample’s exposure to heat. The time
Fire Safety
constant of this assembly typically ranges between 300 to 400 seconds. However, once equilibrium is achieved, this sensitivity may become less significant. Refer to Figure 1
ISO834-1:
The plate thermocouple assembly used in EN 1363-1 and ISO 834-1 consists of a mineral-insulated K-type thermocouple with a nominal diameter of 1.5 to 2mm, securely fixed to a 0.7mm thick Inconel plate. To prevent direct exposure, an insulation pad shields the thermocouple from the specimen side. This design ensures that temperature must first pass through the conductive Inconel sheet before reaching the sensing end of the thermocouple. The assembly is engineered to achieve a more uniform temperature reading, minimising fluctuations during the test.
Table 1: Comparison of standard time temperature data in ASTME119 Vs ISO834 in 4 hours
Figure 1:
Fire Safety
BS476-20:
In BS 476-20, either 0.75mm to 1.50mm bare wire K-type thermocouples or 1.5mm mineral-insulated K-type thermocouples are employed to control the furnace. These thermocouples exhibit the lowest time constants and therefore offer the quickest response times compared to other standards. This rapid response allows the furnace to be controlled more swiftly than with other thermocouple assemblies.
This quick response also results in reduced heat exposure on the specimen.
AS1530-4
Mineral-insulated K-type thermocouples with a nominal diameter of 3mm are utilised for furnace temperature control in this standard. These thermocouples boast a response time comparable to those specified in BS476-20.
EXPERIMENTAL RESULTS ON THE COMPARISON OF HEAT EXPOSURE USING DIFFERENT THERMOCOUPLES FOR RESISTANCE TO FIRE TESTS. We conducted an experiment to assess temperature variations across different
thermocouple assemblies during a fire resistance test.
For the study, we selected the following thermocouple assemblies:
1. ASTM E119/UL 263 thermocouple assembly
2. BS 476-20 thermocouple assembly
3. ISO 834-1 thermocouple assembly (same as in EN 1363-1)
4. AS 1530-4 thermocouple assembly
The furnace was operated using the BS 476-20 thermocouple assembly, known for its rapid response, while temperatures recorded by the other thermocouples were compared simultaneously. Data was logged at 1-second intervals throughout the experiment.
The furnace followed the ISO 834-1 curve (T=345 log10(8t+1) +20, where T represents temperature and t denotes time in minutes).
Results of the Experiment:
A significant temperature difference of up to 300°C was observed during the initial minutes of the test. This difference narrowed as the thermocouples became saturated. Refer to Graph 3 for details. The measured temperatures are also listed in Table 2.
Thermocouples with slower response times produced a smoother curve, as they did not capture the fluctuations in the gas temperature inside the test furnace. In contrast, fast-response thermocouples recorded the exact temperature fluctuations every second, allowing for precise control of the test furnace.

Fire Safety
Inference:
If the furnace is controlled by ASTM E119/UL 263 thermocouples, the actual temperature the specimen gets exposed to at the initial minutes of the test will be much higher than that of BS 476-20. This is to be coupled with the fact that there is a difference in the time-temperature curve too.
Similarly, specimens are exposed to higher temperatures when tested according to ISO 834/EN 1363-1. This is why a test conducted under one standard cannot be considered exactly equivalent to another, even if the time-temperature curves appear the same. The experiment also highlights why instrumentation used for one standard should not be used for another.
FURNACE PRESSURE CONDITIONS AND PRESSURE PROBES
One of the primary requirements for any test furnace is the ability to maintain a neutral pressure plane inside the furnace at the specified height according to the standard. However,
there are some key differences between the test standards.
For tests following the general requirements of ISO 834-1 and EN 1363-1, unless otherwise specified, for all vertical elements, a zero-pressure plane is maintained 500mm above the notional floor level. The height of the zero-pressure plane must be adjusted to ensure that the pressure at the top of the specimen does not exceed 20Pa.
For horizontal elements, according to ISO 834-1, a 20Pa pressure plane is to be established 100mm below the underside of the specimen or the notional ceiling level. In EN 1363-1, the pressure plane for horizontal elements is established relative to the notional floor level, ensuring that the pressure on the underside of the test specimen does not exceed 20Pa.
Additionally, when assessing furnace pressure conditions, ISO 834-1 assumes a pressure gradient of 8 Pa per meter,
whereas EN 1363-1 assumes a gradient of 8.5 Pa per meter height of the furnace.
Even though the difference in measured values may be insignificant, the probes used for pressure measurements vary across different standards. For instance, the tube-type probe used in ISO 834-1 has 3mm holes, while the same probe in EN 1363-1 has 1.2mm holes. Similarly, UL 10C specifies a probe similar to ISO 834-1, whereas UL 263 uses a different probe with 1.5mm holes.
COTTON PAD
The cotton pad test determines the specimen’s integrity during a fire resistance test. Although the cotton pad test procedure appears to be similar in various standards, there are some key differences in the equipment and the time of application.
For tests as per EN and ISO standards, the cotton pad holder is designed in such a way that the cotton pad is 30mm away from the surface of the specimen. In contrast, for ASTM and UL standards, the cotton pad is 25mm away from the sample.
Regarding the time of application, most standards specify a maximum of 30 seconds or until ignition, while BS 47620 limits the time of application to 15 seconds.
Guidelines on the application of cotton pad:
According to BS 476-20, the cotton pad should no longer be used if the temperature on the unexposed side near the gap reaches 300°C, as measured by a roving thermocouple. ISO 834-1 includes a comparable provision.
UL 10C specifies that cotton pads shouldn’t be used on door assemblies where the average temperature exceeds 250°C (450°F) above ambient temperature. Additionally, single-layer metal doors are exempt from the cotton pad test requirements.
Graph 3: Time temperature data as measured by different thermocouples, when the furnace is controlled using BS476-20 thermocouple assembly
GAP GAUGES
Most of the fire resistance test standards specify a 6 mm and 25 mm gap gauge for the evaluation of the integrity of the separating elements. Usually, an Integrity failure is deemed to occur when the specimen allows penetration of a 25 mm gap gauge or when the gap developed in a specimen is large enough for a 6mm gauge to travel a length of 150mm.
However certain standards like EN 1364-2 – Fire resistance test on non-load bearing ceilings exempt the use of gap gauges considering the safety of the laboratory personnel and instead, a visual assessment of the gaps is prescribed.
HOSE STREAM TESTS
The hose stream test, conducted immediately after the fire test, is a crucial requirement in ASTM and UL standards for most separating elements. If a specific standard lacks a procedure for this test, ASTM E2226 guidelines are followed.
The test employs a UL standard playpipe equipped with a 29mm discharge tip to deliver water. Water pressure at the playpipe’s base is set at 30 psi for tests lasting less than 3 hours and 45 psi for tests lasting 3 hours or longer.
The Indian standard for through penetration fire stops, IS 12458 specifies a hose stream test at similar pressure but with an IS903 nozzle instead of a UL playpipe.
In contrast to ASTM and UL standards, EN and ISO standards for fire resistance tests do not include hose stream tests as part of their compliance criteria.
CONCLUSION:
The diversity in fire resistance testing standards poses challenges for international building practices, particularly in regions like India where multiple standards may apply. For instance, a material deemed fire-resistant under one standard may not necessarily meet the criteria of another, complicating cross-border construction projects and the global trade of building materials. Understanding the differences in fire resistance testing across various standards is crucial for architects, engineers, and regulators to design and construct truly fire-safe buildings. By acknowledging these differences and working towards harmonization, the global construction industry can improve fire safety standards, ensuring better protection for people and property worldwide.

The Importance of Smoke Vents in Glass Facades: Design, Function and Maintenance
DOES SIZE MATTER?
Let us begin with two anecdotes, to set the stage.
Anecdote 1 - While visiting a premier company in the region of Mumbai, I spoke to the receptionist while waiting for my appointment and asked, do you know the reason these windows with handles are provided?
I do such awareness tests now and then to understand how much the occupant really knows about their safety in a premises.
Back to the story, she replied, no, I am not aware, is it for natural ventilation? I replied, we are in an Air-Conditioned building, so think again. She replied, is it to escape out of the building in some emergency? I said, you are on the 6th floor, would you make it if you escaped out of this? Then, explained to her the importance that the humble ‘SmokeVent’ plays in any Glass Façade Building, when no other form of
exhausting toxic gasses, and hot thick black smoke are present.
Below is a snippet of the ‘SmokeVent’ section, presently in the National Building Code published in 2016.
If you notice the last line, it drops the onus of opening these vents to the ‘Fire Personnel’ or the YOU - the ‘Building Occupant’.
Ask yourself, as a reader of this article, or if you work in a glass façade building in our region, would you open that window/ vent before you escape and make it to the ‘Assembly Area’ or would you just escape and run for your LIFE?
Anecdote 2 – While visiting a building in Ahmedabad, saw the vent was 2m x 2m, very large and openable with a handle, same awareness test was done, and similar replies came back, however, the vent here did not even budge beyond 10Degs as it was stuck and not maintained. Most of the vents are designed to not open more than 200-250mm.
This now becomes a ‘Very High Risk’ High Rise, where there is a lack of awareness or training for the occupants and/or systems that do not function as designed. In a residential project with a glass façade, the vents, top hung or parallel or sliders will be opened/closed frequently, so eventually they will be maintained by the owner, not the case in large IT/Commercial parks, it’s more fit, handover and forget here.
Also, when we speak to the concerned, their goal is to have very large panels, predominantly to provide fabulous views of the outside. As it’s said, bring the outside in. We are talking of openable with sizes of 1.5m wide x 2.2m and taller, humanly hard, or rather cumbersome to open, and the question is, why should we?
THE CHALLENGES
Large vents without automation bring about a lot of challenges,
1. The fabricators of these glass buildings need to deal with millimeter-level tolerances to make these large panels
Snippet of the ‘SmokeVent’ section, presently in the National Building Code published in 2016
function & pass Performance Mockups
2. Hardware supplies are usually expensive as the vents/windows get larger with a greater number of moving parts
3. We all are aware, that precision and workmanship that can be achieved in a factory condition cannot be achieved at the site. Alignment issues are a concern too
4. The interior fit-out team often opens the vents during their scope, and during rains, this causes flooding inside or even causes the vents or the hardware to get damaged, which is mind you, under warranties from the supplier
5. For this, provide interior contractors with fans or some cooling systems, as these vents/windows are for ‘SmokeVentilation’ only.
6. On handover, if you have a site with over 500 vents, imaging opening and closing each one of them 5 times to prove it works, there is no SOP for this today in the market when vents are manual
7. Handles are removed in some data secure projects owned/leased by large Global and/or Indian companies, this is as good as not having a system
8. Lastly, no awareness is given to the occupants of the system so they are not aware something like this even exists
THE SOLUTION - AND POINTS TO CONSIDER:
Modulation, Automation, Testing
1. Rather than provide a large vision openable, shift the openable slightly higher towards the false ceiling, the rest below becomes your vision
2. This helps to extract the smoke out, as smoke tends to rise due to its buoyancy
3. Vents are to be BHOO - Bottom Hung Open Out
4. Making the vent shorter allows for a greater angle of opening, as the taller the vents, shallow will be the opening & will not allow for effective smoke exhaust
5. Parallel is possible with automation, however, starts to add on costs onto the system, and opening is limited
6. Automation must be by Actuators which are to be of chain type tested to EN12101-02 CE/UKCA
7. Size, weight, Opening Angle, and Wind Loads play a crucial role and need to be taken care of. If wind loads cannot be sustained by just the Actuator, a suitable Multi-Point Locking (MPL) Actuator needs to be used here with Locking Points, should the performance standards be much higher
8. Keeping the vent shorter also allows for fewer moving parts internally thereby making the system less prone to failures
9. Wide vents like in airports or some cases IT/Commercial parks need to have multiple Actuators based on the width, to allow for the necessary clamping/holding with a minimum of 4000N / Actuator
10. To govern the weight, during its operations care to be taken to understand the forces applied, where Actuators must have a minimum of 400N / Actuator open/ close force
11. Calculations must be verified and certified by a project Consultant
12. Lastly, with glass façades tending to move towards fire rates systems, it is important to not only have a tested Actuator but to also test the entire ‘SmokeVent’ and its components to EN12101-02/IS21927-02, reach us to know more
THE SIDE LESS SPOKEN ABOUT
There is a notion that the ‘SmokeVent’ is a façade related hardware system, this is partially correct. However, the system is on the Glass Façade but forms part of the building’s ‘Fire Strategy’, ‘Active Fire Systems’, and ‘HVAC Designs’ as well. 80% of the work lies here, in system design, approvals, proper execution, commissioning with fire alarm systems, and the proper Handover to the End-User/CareTaker/Owner
1. Having smaller AMP controllers allows for shorter cable runs,
controllers and MCP are to be tested to EN12101-10 CE/UKCA.
2. The longer the cable runs, the thicker the diameter/size of the cables, eventually costing more
3. In large public space buildings we can proceed with larger panels of 30/60/90/120AMPS as space is less of a restriction here or cable draws
4. However, for offices and commercial buildings an 8AMP will take care of points 1 and 2 stated here
5. Voltage drop calculations are a must here to be provided by the vendor to the consultants for approvals
6. Locations of controllers play a crucial role too, can be placed at HVAC, ELV, or Fire Command Rooms and must be zonal/local and not centralised, due to cable runs with access to be provided
7. Manual Override or a Manual Control Point must be provided at all stair locations, create an awareness program for the occupants to not tamper with any fire systems, don’t change the norm, change the mindset
8. Now, since the system is installed and is automatic, the Owner/EndUser will and must maintain it via the manufacturer or authorised partners of the vendor providing the system
IN CONCLUSION “SIZE DOES MATTER”
1. Shallower the vent more the opening
2. The higher the placement of the vent, the better for smoke exhaust
3. Cable diameter/size goes up as distances increase, so propose smaller AMP controllers for Office/IT spaces placed zonally or floor-wise controls, do not centralise them and drag cables floor-floor
4. Bear in mind to receive all calculations and drawings on, wind loads, force, cable types, voltage drops, installation details, vent details, SLDs, and BOQ by break-up of systems proposed
5. It is recommended to have smaller vents spaced evenly rather than lesser large vents as they are easier to maintain and care for in the long run of the building life cycle and lesser moving parts internally
6. Stick to a maintenance schedule and do not sub-let maintenance to an untrained professional and later call the system manufacturer.

Rajiv Gandhi International Airport Hyderabad,
Telangana
BACKGROUND
Rajiv Gandhi International Airport (RGIA), located in Hyderabad, is India’s first greenfield airport developed under the Public-Private Partnership (PPP) model. Spanning 5,500 acres, it is one of the largest airports in the country. RGIA plays a vital role in handling over 21 million passengers annually and was the first airport in India to introduce both domestic and international e-boarding services, setting new standards for efficiency and innovation in air travel.
CHALLENGE
A key design challenge at RGIA was ensuring that the automatic smoke vents and make-up air vents met the required opening angles. Considering the large size and weight of the operable panels, achieving proper functionality and safety compliance was a complex task. Moreover, laying the extensive cables needed to connect window actuators and controllers across the vast airport infrastructure posed significant logistical hurdles. The integration of this system into the overall fire safety
framework required careful planning to ensure that the smoke extraction system would operate reliably during emergencies.
SOLUTION
To meet these challenges, bespoke chain actuators were developed and installed, tailored to the specific weight and dimensions of the smoke and make-up air vents. The system was also equipped with multi-point locking (MPL) actuators that work in conjunction with the chain actuators to meet weather performance standards. When the system is activated, the MPL actuators disengage the locking pins, allowing the chain actuators to open the vents. Upon resetting the fire alarm panel, the system operates in reverse, with the chain actuators closing the vents and the MPL actuators reengaging the locking pins.
The smoke vents, which are bottomhung and open outward, were designed to release smoke and heat from the building during the early stages of a fire. This early smoke extraction helps control its spread, enhances visibility,
and provides safer evacuation routes. The top-hung make-up air vents, which also open outward, allow fresh air to enter the building, improving the natural extraction of smoke through roof hatches and ensuring balanced airflow for more effective smoke removal.
The system was integrated with a robust controller network, ensuring reliable and seamless operation during fire emergencies. All components adhere to international safety standards, such as EN12101, ensuring that RGIA’s safety systems meet global benchmarks. Additionally, the system is fully integrated with the Building Management System (BMS), enabling the maintenance and operations team to monitor the health and status of the controllers in real-time. This proactive communication allows for early detection of potential issues, improving operational efficiency and ensuring the reliability of the system.
The implementation of this advanced system not only enhanced the overall safety of the airport but also demonstrated the innovative use of technology in large infrastructure projects, setting a new standard for both safety & operational efficiency.

Jio World Centre - A Place for Cultures and Communities
BKC, Mumbai
BACKGROUND
Spread over 18.5 acres, Jio World Centre is a multifaceted development where people will get together, to appreciate art, to exchange ideas, to celebrate culture, and to soak in the heritage and vibrancy of our great city.
JWC is a stunning new landmark for India, as well as a prime location for business, leisure, entertainment, and retail in the prestigious precinct of Bandra Kurla Complex.
CHALLENGE
Enabling client’s and architect’s vision to have state-of-the-art, perimeter façade smoke ventilation systems, using Automatic Opening Vents (AOV) along
with India’s first glass façade Automatic Fireman Access Doors (A.FMAD).
SOLUTION
The solution was to provide actuators that fit the purpose and design intent of perimeter façade smoke ventilation to the Free Area Requirements, with compatible control systems to enable the opening of these AOVs and Automatic Fire Man Access Doors on the building envelope.
All our actuators are tested to the stringent code of EN12101-02 and compatible OS2 Controls with up to 72 hours of battery back-up and Manual Control Points as per EN12101-10.
Though our region, at this stage, does not have a code of practice for this system, we ensured the system was designed, to the extent possible, to meet with BS7346-8 Code of Practice for planning, design, installation, commissioning, and maintenance of these Smoke Control Systems, for this, and other projects we are awarded in our Region.
As with all systems of this type, there are two key roles:
1. To protect escape routes, venting smoke away from them to allow occupants to evacuate the building, also keeping the perimeter of the fire floor relatively smoke-free, ensuring reduced chances of a flashover as well.
2. Provide greater access to the firemen, allowing them to tackle the fire more effectively.
BENEFITS OF THE SYSTEM
Fire safety is of major importance in any building but especially so in one
like JWC, which annually is visited by hundreds of thousands of visitors. The Smoke Clearance System is therefore seen as a life safety system and brings two key areas of benefit:
From a safety point of view:
• Keeps fire floor’s perimeter, public escape, and access routes relatively free from smoke.
• Improves visibility within the building allowing the fire service to facilitate operations, and occupants to be able to see better.
• Delays and /or prevent flashovers and full fire development. Thereby reducing property damages from a developer’s point of view.
• Reduce the effects of heat on structural components during a fire.

Design for Passive Fire Protection and Safety of Buildings
Passive fire protection is a critical aspect of building design, and recent fire events have underscored its importance. By understanding the main concerns, implementing effective passive fire protection measures, and adhering to current regulations, we can ensure the safety of buildings and their occupants. Additionally, careful consideration of curtain wall design and spandrel zones is crucial in preventing fire spread. Architects, engineers, and builders need to prioritise passive fire protection in their designs to create safer buildings for everyone.
The Dubai Address Downtown Hotel fire (2015) and the Grenfell Tower fire in London (2017), two of the most emblematic events from the last decade for global visibility impact the first and for the number of losses in lives the second, are stark reminders of the importance of fire-safe cladding, compartmentalisation, and fire-resistant materials. These fires have led to a renewed focus on passive fire protection, emphasising the need for effective building design and materials to prevent fire spread.
Compartmentalisation, fire stopping and sealing, material selection, and structural integrity are crucial aspects of passive
fire safety. By dividing buildings into fire-tight compartments, preventing fire spread through gaps and joints, selecting fire-resistant materials, and ensuring structural integrity, we can significantly reduce the risk of fire spread.
Passive fire protection of main structures is critical, and measures
include using fire-resistant materials, applying protective coatings or sprays, and designing structures to withstand fire exposure. Current regulations in different countries, set minimum requirements for fire safety; despite that, there is still a wide gap to cover, in regulations but also in understanding the real magnitude of the issue, especially

in the curtain wall construction which is widely used for wrapping buildings due to their aesthetic appeal and they are lightweight combined with the higher performances currently reachable in terms of energy saving and green economy.
Curtain walls and spandrel zones require special attention, as they can be vulnerable to fire spread. Testing and certification,
material selection, jointing and sealing, and ensuring proper insulation are essential to maintain fire resistance.
THE FIRE SAFETY OF CURTAIN WALLS: A CRITICAL DISCOURSE
As we gaze upon the sleek and modern façades of contemporary buildings, it’s easy to overlook the intricate details that ensure the safety of their occupants. One such crucial aspect is the fire safety of curtain walls – a topic that warrants rigorous examination. In this discussion, we’ll delve into the complexities of curtain wall fire safety, navigating the nuances of testing and certification, material selection, jointing and sealing, spandrel zones, insulation, fire-stopping, and maintenance and inspection.
TESTING AND CERTIFICATION: THE BEDROCK OF FIRE SAFETY
The importance of testing and certification cannot be overstated. It’s the foundation upon which fire safety is built. Without rigorous testing, we’re left with a curtain wall system that may appear aesthetically pleasing but potentially harbours hidden dangers. Certification bodies must simulate various fire scenarios to assess the curtain wall’s performance, providing a safety net for occupants.
MATERIAL SELECTION: A DELICATE BALANCING ACT
The selection of materials for curtain wall construction is a precarious balancing act. On one hand, we desire materials that provide structural integrity and aesthetic appeal; on the other, we must

prioritise fire resistance. The dichotomy between form and function is palpable. Fire-resistant materials like fire-resistant glass, ceramic or stone veneers, and fire-treated wood or aluminium frames are the obvious choices, but what about the less conspicuous materials like insulation and sealants? Their impact on fire safety should not be underestimated.
JOINTING AND SEALING: THE ACHILLES’ HEEL OF CURTAIN WALLS
Jointing and sealing are often the most vulnerable aspects of curtain wall construction. Gaps and joints provide a conduit for fire to spread, compromising the integrity of the entire system. The importance of proper jointing and sealing cannot be overstated. Fireresistant sealants and gaskets should
be employed to prevent fire from penetrating the curtain wall, and joints must be meticulously aligned and sealed to prevent fire spread.
SPANDREL ZONES: THE HIDDEN VULNERABILITY
Spandrel zones, nestled between floor slabs and curtain walls, are a frequently overlooked vulnerability. These areas require special attention, as they can provide a conduit for fire spread. Fireresistant materials and fire-stopping measures must be employed to protect these areas, ensuring that fire cannot spread through the curtain wall.
INSULATION: A HIDDEN HAZARD
Insulation, often an afterthought in curtain wall construction, can pose a significant fire hazard if not properly
selected and installed. Fire-resistant insulation materials like mineral wool or ceramic blankets are essential, and proper installation and sealing are critical to prevent fire spread.
FIRE-STOPPING: THE FINAL LINE OF DEFENCE
Fire-stopping measures are the last bastion of defense against fire spread. Fire-stopping is a critical component of passive fire protection, and it refers to the measures taken to prevent fire from spreading through gaps and joints in the curtain wall. These gaps and joints can be vulnerable to fire spread, as they can provide a pathway for flames and hot gases to travel through the building. This final line of defense is crucial in preventing the fire from spreading through the curtain wall.

Fire-stopping measures typically involve the use of fire-resistant materials, such as fire-resistant caulk or spray, to seal joints and fire-stopping elements to fill the gaps between the façade and floor slabs. These materials are designed to maintain their integrity even when exposed to high temperatures, and they can help to prevent fire from spreading through the curtain wall.
Some common fire-stopping measures include:
1. Fire-resistant caulk: This is a type of sealant that is specifically designed to resist fire. It can be used to seal joints in the curtain wall.
2. Fire-resistant spray: This is a type of spray that is applied to the curtain wall to provide a fire-resistant barrier. It can be used to seal joints.
3. Fire-stopping systems: These are pre-engineered systems that are designed to provide a comprehensive fire-stopping solution. They typically include a combination of fire-resistant materials and other components.
4. Penetration seals: These are used to seal joints around penetrations, such as pipes and ducts, that pass through the curtain wall. They can help to prevent fire from spreading through the building by sealing these vulnerable areas.
5. Joint seals: These are used to seal joints in the curtain wall.
Overall, fire-stopping measures are a critical component of passive fire protection, and they can help prevent fire from spreading through the curtain wall. By using fire-resistant materials and installing fire-stopping systems, building owners and managers can help protect people and property from the dangers of fire.
MAINTENANCE AND INSPECTION: THE ONGOING VIGILANCE
Regular maintenance and inspection are the unsung heroes of curtain wall fire safety. Curtain walls must be inspected regularly for damage or deterioration, and maintenance tasks like cleaning and repairing sealants must be performed to ensure the curtain wall remains fire-resistant. This ongoing vigilance is essential in ensuring the fire safety of curtain walls.
In conclusion, passive fire protection is a critical aspect of building design, and recent fire events have underscored its importance. By understanding the main concerns, implementing effective passive fire protection measures, and adhering to current regulations, we can ensure the safety of buildings and their occupants. Architects, consultants, and builders must prioritise passive fire protection in their designs to create safer buildings for everyone.

The Crucial Role of Perimeter Firestops in Fire Containment
Drawing from extensive expertise in façade assessment and inspections, there is a need to understand the paramount significance of perimeter firestops as a critical element of fire containment.
Perimeter firestops act as a barrier to prevent flames from entering a room above via the void created at the intersection of a floor slab and the interior face of the exterior wall assembly. This crucial aspect of fire containment is often overlooked but remains essential in mitigating the rapid spread of fires within a building.
International codes such as the International Building Code (IBC) comprise specific requirements for perimeter fire stops. In India, the Fire Safety Sectional Committee took a serious interest in this particular building element and issued IS 18190 : 2023 Fire Resistance of Perimeter Fire Barrier Joint System — Method of Tests which signifies the importance of this test as a full assembly.
Throughout various project phases, the following processes should be addressed, encompassing design considerations, certification and testing procedures, as well as installation and inspection processes. There are several overarching procedures
these systems can undertake to ensure compliance and increase building safety, spanning from manufacturing to meticulous installation:
System Design:
Designing the perimeter fire barrier involves creating an integrated system placed in the void between the interior surface of the external façade or curtain wall spandrel, and the slab edge or floor assembly. This system primarily comprises two elements: a firestop material and a smoke barrier. Despite its apparent simplicity, ensuring effective design involves critical steps in integrating these longitudinal joints with the curtain wall and the slab sides. Below are crucial considerations to account for when crafting such systems.
The initial aspect pertains to the design of the curtain wall spandrel and its interaction with the system. Spandrels, part of the curtain wall, conceal slab elements such as bracket fixations and floor-to-floor separations. Various codes mandate specific spandrel heights and fire ratings. The composition of spandrels— whether back pans, insulation boards, or other materials—significantly influences the overall performance of the containment system. These elements constitute the system’s outer side and must be accurately represented in a test assembly to ensure
seamless integration and continuous support for the firestop system during testing.
On the opposite side of the system attachment lies the concrete slab or floor assembly. Considerations include the fixation method, spacing between supports, primer application, and the design of the smoke seal.
Another crucial factor in the design of the perimeter fire barrier is the joint width and tolerance. Each system has a specified maximum gap allowance. Construction sites involve multiple packages managed by different parties, resulting in built elements possessing allowable deviations in alignment, known as tolerances. While slab edges may have tolerances of ±25mm, external façade systems often adhere to a tolerance of ±3mm. A successful firestop system must flexibly accommodate such tolerances while functioning optimally.
The joint movement stands as another critical consideration. External façades and curtain walls endure external forces like wind loads and building movements, rendering perimeter gaps between slabs and façades as active joints. Therefore, perimeter fire stops necessitate design considerations that accommodate these cyclic movements effectively throughout the project’s life.

Figure 2: the ASTM E2307 Test
Fire Safety
A sample representing the system should be consciously chosen, considering all the aforementioned factors, to demonstrate its performance effectively.
Manufacturing and Certification:
The certification process ensures that the materials and components of the system are produced under a quality control framework, ensuring uniformity and consistency in the final product. Within this process, components undergo controlled sampling and subsequent testing using representative assemblies to showcase their capability as a complete system. Following successful test completion, the system attains listing as an assembly in a certification directory. Ongoing surveillance audits are carried out to ensure manufacturing is conducted in a consistent manner. An instance of this is featured on WWW.TBWCERT.COM, showcasing its performance and specifications to assist architects and façade consultants in selecting suitable systems. Ratings enumerated in certificates are derived from test outcomes.
When tested as per ASTM E2307 or its Indian equivalent Standard, IS 18190, the F rating and T rating are critical measurements used to evaluate the performance of perimeter fire stop systems. These ratings assess the system’s ability to resist the passage of flames and limit the transfer of excessive heat during a fire.
These ratings are determined through specific testing procedures outlined in ASTM E2307 or its Indian equivalent Standard, IS 18190. The test involves subjecting the perimeter fire barrier system and the adjacent curtain wall system to fire conditions that simulate a real-world scenario, evaluating its ability to contain flames and restrict heat transmission across the barrier.
Understanding these ratings is crucial for builders, designers, and regulatory authorities to ensure that perimeter firestop systems comply with safety standards. It helps in selecting and installing systems that effectively contain fires, safeguard occupants, and minimise property damage during fire incidents.
Installation: The installation of these systems must adhere to regulations that mandate certified contractors to perform the task. Moreover, prudent companies with certified and listed systems exclusively permit licensed contractors for installation, ensuring they undergo extensive comprehensive training to understand the crucial steps involved in the installation process.
The contractor must closely follow the manufacturer’s guidelines regarding cutting, fitting, compression ratio, anchoring, and maintaining smoke seal integrity. This strict adherence is crucial to have a proper perimeter firestop system at the intersection between the façade and the slab.
Moreover, details specified in the certification report, encompassing the description of curtain wall design, spandrel design, mullion protection cover, as well as dimensions and materials, necessitate thorough scrutiny by the consultant to ensure compliance.
Inspection by a Third Party:
Inspection by a Third Party accredited to ISO 17020 plays a pivotal role in the procedure. It involves documenting the installation of these pivotal joints and serves as evidence of rigorous quality control throughout all phases. ASTM E 2393, titled “Standard Practice for OnSite Inspection of Installed Fire Resistive Joint Systems and Perimeter Fire Barriers,” Scheduling inspections from the onset, considering these hold points are deemed significant in construction, occurring before concealment by finishes.
Every project involves a collaboration among numerous stakeholders. The dedication of all involved parties— including the manufacturer, consultant, contractor, and inspection team—to quality assurance and effective collaboration is pivotal for successful outcomes.

The Demand for Fire Rated Doors, Partitions and Curtain Walls in India
The fire-rated door, curtain wall and partitions market in India is estimated to grow at a significant CAGR of 5.1% over the forecast period and is poised for growth with a promising outlook fuelled by urban development, regulatory requirements, and increased safety awareness. Cities are becoming congested worldwide. Our constructions are reshaping the skyline and making it more challenging to navigate between each building. It is now essential that we plan our structures to be self-sufficient in the event of a fire for this reason. The very least we can do is make sure the supplies we utilise will aid in human rescue—either by a clear, organised route to safety or by allowing them adequate time to assemble in a secure location. Await the arrival of the fire department. Only with appropriate measures can people’s lives and property be safeguarded.
Architects who wish to maximise benefits like natural light, space, and practicality are increasingly specifying fire-resistant curtain wall to meet architectural criteria and add crucial services like fire safety, especially for commercial buildings.
Fire protection systems divide the building’s floor plate into compartments using fire-resistant partitions, doors, and curtain wall systems to stop the fire from spreading. These systems rely on actions performed during the building process, such as planning escape routes and comprehending the fire behaviour of building materials. They also rely on compartmentalisation to contain the fire as much as feasible.
When fire partition and curtain wall products with visibility are required under normal circumstances, fire-rated curtain walls, partitions, and doors are utilized. A fire-rated glass divider and fire-rated completely glazed systems accomplish this. Clear visibility is maintained under normal circumstances and a fire barrier is formed during a fire thanks to the specifically developed glazing system that holds the fire-rated glass in place. Although other firerated materials are capable of offering this level of protection, only fire-rated glass and systems can do so without compromising the complete vision for aesthetic, daylighting, and security reasons.
Fire-rated glass, curtain walls and partitions enhance light transmission and visibility while offering vital fire safety. Non-fire spreading (NRO) is the classification given to the systems. The most exacting standards for life safety in commercial and industrial settings are met by the construction of fire partitions and windows, which compartmentalise and restrict the spread of fire. The walls provide maximum human safety in addition to enhancing the current passive firefighting systems.

The architects spoke about the beginning of their firm and major milestones, most interesting projects, façade designs and much more. Here are the excerpts from the interview.
Face to Face
When was the design firm Venkataramanan Associates established? Please tell us about your journey so far Naresh Narasimhan (NN): Venkataramanan Associates (VA) was founded on the first of November 1969 – Karnataka Rajyotsava day, by my father, fondly called PKV by all. He had trained as an architect at Delhi Polytechnic, which went on to become the School of Planning and Architecture (SPA), Delhi. My father had begun his career at a time when no one knew what architecture was. Buildings were designed by Maistri’s, Sthapatis and engineers. He never entertained the hubris of a star designer and preferred to dedicate his energies to his craft. Working at a time when everything was scarce - money, materials and choices, his architecture was driven by the necessity to detail rather than its conceit. Driven by his passion for architecture and honest ambition, in its early days the firm built a series of houses, apartments, commercial buildings, cinema theatres, and institutional buildings amongst many other typologies, particularly in Bengaluru.
VA has grown from strength to strength over the years and is one of the very few large, indigenously grown full-service architecture firms in India. Having completed fifty years in 2019, the firm has successfully pre-empted the economic shifts of the last five decades in the country and positioned itself as a driver of change. Today, with offices in Bengaluru and Pune, the firm has inbuilt expertise to deliver across various market domains and categories, but the core philosophy is rooted firmly in the belief that design is implicitly about human experience across all scales and hence needs to be outcome-based. Very early, we learned that to be resilient to external influences, the firm would need to diversify its competence across various domains, project typologies, and geographies. Today, the office continues to push
the boundaries of design and detailing in the traditional domains, while also pioneering novel typologies. Having delivered over 2000+ projects in diverse sectors, totaling over 160 million sq ft, VA’s association with Fortune 500 giants or the government in urban design and large-scale infrastructure projects, is reinforced by an informed, collaborative and iterative process used by the teams of over two hundred professionals,
across the offices. Organised across diverse practice areas and a broad spectrum of industry sectors, science & technology (S&T), corporate, industrial & manufacturing, logistics & warehousing, institutional, residential, commercial & retail sectors, at VA we have developed the capability to deliver a range of project types for clients from around the world. Our interdisciplinary staff has proved time and time again that intelligent, evocative design can be realised within real-world constraints. The firm has also developed comprehensive capabilities in setting up facilities for both Indian and International best practices and codes.

Please tell us about a few of your milestone projects
NN: Prior to economic liberalisation in the eighties and nineties, VA, under the leadership of PKV, built a lot of residential and institutional projects for some of the premier institutes in Bengaluru like Raman Research Institute, Indian Institute of Science and simultaneously the firm was also strengthening its portfolio by adding new real estate clients all the time. Some of the breakthrough projects that VA did in the residential real estate industry include projects like The Embassy, Adarsh Palace, Purva Park. Alongside, VA was also breaking ground in newer typologies that were emerging in commercial real estate in Bengaluru with the boom in the outsourcing and IT industry with projects like Embassy Point , a series of projects for Prestige developers like Copper Arch, Westminster, Ozone and others. We were very exposed to the real estate crisis of the 90s when it happened, post which we actively decided to pivot our attention to other sectors.
I remember a chance introduction to ABB (ASEA Brown Boveri) was our first
breakthrough in doing architecture projects for corporate clients. We had made some utilitarian adjustments at their factory in Peenya, which led to a corporate office for them in Bombay. We also had an opportunity to pitch for a corporate office for a company called SmithKline Beecham which resulted in a model office building with

very early intelligent building controls. Simultaneously we also won a project for Pharmacia, who produced intra-ocular lenses and needed very specialised cleanroom technologies in their building. At that time the knowledge and availability of such technology was scarce, but we persevered. That building had the first ice-tank-based air conditioning system in India, and it had some of the earliest building control systems using Johnson Controls.
We continued making a foray into sectors that were not only new to us but also to India. The late 90s and early 2000s saw a steep incline in the growth and fortunes of VA. The master plan for the first Infosys Software Park was developed and designed by VA. We eventually got offered their campuses in Pune, which led to the establishment of the Pune office. The John F Welch Tech Centre for GE was another research and laboratory facility that we designed which presented a huge learning curve for us, but we ended up establishing the world-class standard in research labs for GE worldwide. This was a big breakthrough project that really

crystallised our expertise and leadership in designing buildings that needed specialised environments. While the project demanded very high technical standards in environment separation, our innovative design thinking not only achieved this but also broke existing stereotypes by achieving “boundaryless, open office” spaces. Other projects in which we continued pushing boundaries were the Astra Zeneca labs, Reliance Life Sciences and Reliance Technology Center in Patalganga. Gradually we also designed facilities for Biocon, Dupont and almost every other top name in the Indian industry.
While the interior environments of these projects were crucial, in designing them we were also focused on how the buildings interfaced with the outside. From the beginning and continuing with projects like the Infosys master plan, our endeavour has always been to create buildings that are performative through their architecture and envelope. The façade is not merely a boundary to be dressed up but it’s the crucial membrane that can be used to express identity, control interior environments, and connect the interiors with the
landscape. We have been focusing on employee wellness, experimenting with new technology and sustainability paradigms long before they became de rigeur
Even while we were actively diversifying our design expertise and experience, we were introducing new technology in our real estate projects which continue to be our strongholdEmbassy Heights , the first building in Bengaluru with structural glazing, was the result of a lot of research. Projects like the Nirlon Knowledge Park and the Wipro Kodathi campus demonstrate that our designs are unmatched in how meticulously we can incorporate climate-appropriate, technology-first solutions in diverse locations. In mixeduse real estate projects at the scale of Brigade Gateway and Prestige Falcon City we can deliver at the same levels because, over time, our diverse, interdisciplinary, and multi-dimensional teams have nurtured the necessary talent and expertise.
Throughout this journey, we have always believed in giving back and making a difference to the city and our immediate urban environment. Today projects like the K100 Citizen’s Waterway, conceptualised by the Mod Foundation, which is VA’s notfor-profit sister concern, have had their beginnings in early projects like NGMA that we did in the early 2000s. I had begun getting engaged with civic activism with the O’Shaughnessy Road Park which is right next to our office. I had also served on the Bengaluru Action Task Force (BATF) and always had an interest in urban design since college. We started proposing small interventions in the city, like Church Street , which we did pro bono. We brought all our experience in the private sector to public projects with the intent to deliver high-quality public space for Bengaluru. Today I can confidently say that at VA we know how to design, design for effective construction and all kinds of complexities when it comes to buildings. Our new challenge and unexplored frontiers are the urban and the city.

Ar. Dhiraj Chilakapaty, tell us about yourself, your education, and your career so far
Dhiraj Chilakapaty (DC): I earned my master’s degree in architecture from Universitat Pompeu Fabra, Spain (Barcelona Institute of Architecture), where I developed a focused interest in energy and outcome-based design across scales. My graduate project, The Gold of Tordera , received the highest honors; it presented strategies to optimise Delta Tordera’s (Spain) productive and energetic capacities for economic and social sustainability. I completed my bachelor’s in landscape architecture at Jawaharlal Nehru Architecture and Fine Arts University, where my thesis addressed “Urban Voids,” exploring ways to activate neglected urban spaces with programs that rejuvenate public spaces.
With over 14 years of experience in architecture and urban design— primarily with Venkataramanan Associates—I’ve developed a perspective that champions inclusive, functional public spaces. My work includes designing large campuses and streetscapes, which has deepened
my commitment to user-centric and participatory design principles. I’m passionate about challenging traditional development models, promoting public spaces as integral elements of urban life, and exploring innovative concepts for future housing and workspaces. By creating spaces that serve functional needs and connect with their communities, I aim to craft environments that are not only livable but also meaningful and resilient.
How do you define “resilient façades” in the context of building safety, and what key principles do you believe are essential for achieving this resilience?
DC: The notion of resiliency in buildings needs to be looked at holistically and using a bottom-up approach, which means every aspect of the building design should be guided by principles of building performance. Façades present the threshold where the internal environment of the building interfaces with the external environment, and like the human skin, it helps regulate the internal environment while simultaneously responding to external stimuli. Hence, like in an organism, the façade must be part of a resilient building system. Façade design must be evidencebased and driven by the building’s energy performance targets. The performance parameters of the façade need to be evolved through data-driven design and at the same time through its design, establish an identity for the building, and allow it to communicate with the urban environment through place-making.
In the Earth Center for Vista Spaces , we conducted extensive studies on

the façade, gathering data on solar exposure and heat gain to arrive at empirically driven design decisions. The way the façade uses massing and integrates shading is a direct result of mitigating the solar exposure on the building faces. This also results in programmable landscaped terraces adjacent to indoor workspaces, promoting employee well-being in
the built environment. The material choices of the façade conceptually invoke returning to earth, emphasising the symbiotic relationship between the building and nature. Terracotta tiles used as cladding not only speak to the above need but are recyclable and reinforce the sustainability aspects of the project.
What role do innovative materials and technologies play in ensuring the resilience of façades, particularly in the face of climate change and extreme weather events?
DC: Materiality isn’t about aesthetics alone; it is a language that speaks of tactile experience, durability and sustainability. Every material choice tells a story, shaping our built environment and our relationship with it. Material choices are also evaluated based on their embodied energy even before they are used on site as that determines the carbon footprint of the building. One must strike a very fine balance between the aesthetic needs of a project but also how materials contribute to the performance and life of the building envelope. Technology and material innovation need not always be hightech, and often ground-up innovation can be equally sustainable and resilient in the long run.
In the 3D technology center for Peekay Steels , we have extensively used zinc as a material in the façade. Zinc is 100% recyclable and can be recycled indefinitely. One needs less

energy to produce zinc than the other principal metals in the building industry and hence it has a very low embodied carbon footprint. It also has exceptional longevity - rolled zinc can easily weather 70 to 100 years depending on the environment.
In the Nirlon Knowledge Park , which is situated in Mumbai where buildings must withstand fierce monsoons, we have used terracotta cladding in ventilated façade screens which creates an additional breathable layer of insulation to protect while at the same time positively influencing the building’s energy balance. The terracotta’s uniqueness and adaptability helped maintain a coherent identity over the project’s long and phased development.
How do you approach the integration of sustainable practices into façade design to enhance both resilience and environmental performance?
DC: Before one looks at active design, a lot can be done with passive design. Factors such as orientation, location of the core, and a climate-responsive façade
help bring down the impact of solar exposure and radiation on buildings. The performance of buildings needs to be looked at from every detail and not just as a retrofit or top-down solution. The envelope should be designed in coordination with eVAC systems to reduce the long-term operational and energy costs of a building. Today, one can leverage available technology to quantify and gather data and make informed design decisions. Even in sectors such as real estate, the approach to sustainability is changing and is being looked at holistically with a greater focus on user well-being and comfort.
In the Earth Centre, simulation studies helped understand the impact of aspect, orientation, and radiation. Passive design strategies were incorporated to develop the form with recessed balconies and lobbies for shading and comfort. The design was able to reduce overall heat gains to 30%, due to the climate-responsive building form and low window-to-wall ratios on the lower floors, as against 50% in an all-glass building. Shaded and landscaped terraces resulting from the inherent geometry of the building helped reduce incident solar gains by almost 12%.
How do you navigate the balance between aesthetic considerations and safety requirements when designing façades for different types of buildings and contexts?
DC: Safety is paramount and nonnegotiable. Making a building climate responsive without compromising on safety is just a basic functional need. Given increasing incidences of inclement weather in urban habitats due to worsening climate change, safety and resilience have gone beyond just structural and fire safety. Buildings need to withstand the vagaries of nature and not just basic wear and tear over time to be resilient. Materials need to consider context, program, stability, longevity, and performance. Metrics such as embodied carbon and operational carbon also need to become part of the design conversation to make an impact. Simultaneously the aesthetic and visual impact of a building is the paramount requirement for architecture. Finding the right balance between all of these is critical. The best way to achieve this is to look at design holistically and engage in collaborative conversations with the various experts who bring diverse expertise to building design today.

Face to Face
What strategies do you employ to ensure that façade designs comply with relevant building codes and regulations?
DC: Compliance with the relevant statutory codes is mandatory for envelope design. Apart from the actual design of the façade, these codes also dictate the construction and fabrication, and assembly of façades. Today at VA we can competitively negotiate various diverse codes as required by the project, from the NBC (National Building Code) 2016, ASTM/EN (American Society for Testing and Materials), CWCT (Centre for Window & Cladding Technology) amongst others.
We also consider green building standard compliances such as IGBC and USGBC when designing our buildings. With many corporate clients demanding certifications to ensure they meet their Environmental, Social, and Governance (ESG) goals and opportunities with respect to sustainability, it has become a standard practice in design. With Earth Center, we have targeted LEED platinum certification, and we are on track to receive it. Today, increasingly even in real estate developments, compliance
with green building standards results in favourable marketability and finance avenues for clients.
How do you collaborate with other professionals, such as engineers and sustainability experts, to optimise the resilience and safety of façades throughout the design and construction process?
DC: Architectural design is increasingly becoming more collaborative and needs timely multidisciplinary inputs from various subject matter experts. Architectural designers can no longer follow hierarchical processes with consultant input being restricted to retrofitted solutions to an existing design. In fact, the process has become completely iterative with different consultants giving input in the design as early as site analysis. We engage façade and sustainability consultants at a very early stage in the design of buildings for their input in achieving building form that can optimise for site orientation, solar exposure, structural and functionality needs. The design of building envelopes is measured against performance, beyond just aesthetics. As architects and design leads, we
are constantly trying to find the balance between aesthetic ambitions, constructability and sustainability targets in collaboration with the other experts.
In the Prestige Shrihari Khoday auditorium , the façade and envelope were a result of pushing the functional possibilities of the project with the rooftop terrace. This resulted in a façade that had to be structural and load-bearing as well as provide optimal comfort in the internal spaces. This was achieved through the necessary inputs of the structural and façade consultants. Fine-tuning the structural solutions through design helped us achieve the visually stunning façade.
With the increasing frequency and severity of natural disasters, how do you future-proof façade designs to adapt to evolving climate-related risks and ensure the long-term safety and durability of buildings?
DC: It is well known that the construction industry has been one of the biggest contributors to climate change. Traditional ideas of envelope design had to factor in seismic conditions and wind only, but today with increasingly incremental weather conditions one must look beyond the standard needs. Urban flooding has become very prevalent in all our cities and unpredictable rain and ingress of water is also concerning. A watertight envelope is critical for building performance and longevity. An airtight envelope is very important to support the performance of HVAC systems. For Nirlon Knowledge Park , the façade was designed as a ventilated screen , which allowed the envelope to breathe in the extremely humid conditions of Mumbai and to weather its severe monsoon. This would mitigate the weathering of the building, making the maintenance of the façade easier and countering solar gain by shading the glazed expanses.
The Prestige Srihari Khoday Center for Performing Arts
Prestige Srihari Khoday Center for Performing Arts (PKCPA) Bengaluru
Prestige Falcon City, Konanakunte, Bengaluru
The Prestige Srihari Khoday Center for Performing Arts was built as an amenity for a mixed -use development for Prestige Group at Falcon City master plan alongside a series of residential towers and a commercial mall. The project includes a full auditorium and performance venue, a large banquet space, and an accessible rooftop space.
The section derived from the auditorium’s functional requirements accommodates green rooms, rehearsal spaces, lobbies, and exhibition spaces below the concourse. A large banquet facility for communal events and a kitchen sit under the auditorium on the lower ground level and adequate parking has been accommodated in two basements. The rooftop extends the recreational space of the park, which is
located just behind the auditorium, in a sectional sweep.
In section, the building’s roof begins in a steep incline beginning from the
park behind extending to a peak in the front, creating a massive arrival portico. This inviting gesture is also articulated by the structural supports that hold the roof up at its highest point. The long and slender crisscrossing pylons form a four-storey truss that holds up the roof while shading and protecting the glazed faces of the building’s public spaces. The roof’s incline is derived from the incline of the auditorium and results in a form that could double as an openair amphitheater that overlooks the park beyond. Functionally, the façade is a three-storey structural frame

Entrances for the banquet and parking, peeling up from the hardscape in the front are also rendered in granite as part of the plinth. While the project was intended to have a very specific and specialised function, the interpretation of the form resulted in additional
usable spaces like the banquet and the rooftop which is often used for sunset time outdoor movie screenings. The ease with which the roof becomes accessible also helps activate and connect the various other programs of the masterplan.

The Earth Centre
Whitefield, Bengaluru
The Earth Centre by Vista Spaces was designed to reimagine the idea of workplaces, particularly in the techrelated industry. Core principles of biophilia, promoting a strong connection between nature and the built environment, strongly inform the design fostering employee wellbeing and productivity. The goal was to not just design a benchmark workspace that is sustainable and harmonised with nature but also to reimagine ideals of spatial luxury in workspaces.
To create a high-performance, energyefficient facility, the design process incorporated several simulation studies to understand the impact of aspect, orientation, and radiation. Volumetrically the program requirements are contained within two linear blocks set perpendicular to one another. Passive design strategies
incorporated in the design resulted in the articulation of the very long façades, integrating landscaped terraces all along its length. These outdoor terraces get staggered across the floors ascending gradually and enable breakout spaces for users and visual connections across multiple floors.
The composition of the façade also results in three distinct climate and material strategies to mitigate solar gains. At the base level, contiguous with the street, the building mass is clad in terracotta tiles, visually humanising its large scale and invoking the idea of ‘earthiness’. Above this base the fenestrations at the mid-levels are recessed, with laminated clear glass windows that allow for the interior spaces to visually access and blend into the landscaped terraces. The uppermost levels are glazed using high-performance curtain walls to
take advantage of the surrounding views and maximising daylighting. Terracotta-clad screens in front of this glazing shade the glass to prevent glare inside the workspaces. The formal strategy to manipulate the building mass and the materiality allows for optimal energy and lighting performance in the building.
The project was intended as a multi-tenant development and hence rentable space floorplates would need to be configured incrementally, depending on need. In addition to the office floorplates the project also had to provide for well-defined vehicular and pedestrian access, with segregated drop-off lobbies, and access to other forms of mobility. Urban amenities like gyms, cafes, retail spaces and others made up the rest of the real estate requirement to service the building’s users. Envisioned as a workspace of the future, the Earth Centre by Vista Spaces aims to be a green building that would comply with the highest possible green building rating system with a focus on wellness.

FACTORS CONSIDERED WHILE DESIGNING FAÇADES TO ENSURE STRUCTURAL SAFETY
The structural safety of façades is essential, particularly under varying environmental loads like wind, seismic forces, and temperature fluctuations. As façades protect buildings from external elements, their resilience ensures long-term durability and safety. Here, industry experts share insights on key considerations for façade safety.
Ar. Gurpreet S Shah, Principal Architect & Urban Designer, Creative Group LLP says that in our façade designs, structural safety against wind pressure, seismic forces, and temperature changes is a top priority. We employ high-performance materials and systems that withstand intense wind pressures, especially in exposed environments like railway stations and airports. Reinforced steel and concrete enhance stability in these settings. For seismic protection, flexible joints and reinforced structural elements are incorporated to absorb and dissipate seismic energy, reducing earthquake damage. This approach has proven crucial in seismic-prone projects such as the Kartarpur Corridor and Naya Raipur Railway Station. Temperature variations are managed by using materials like aluminum composite panels and glass, which expand and contract without compromising structural integrity, ensuring longevity.”
Ar. Jaideep Thareja, Founder and Principal Architect at Jaideep Thareja Architects emphasises the need for ensuring façade safety, and it requires accounting for the structure’s weight and external loads. He adds that this involves assessing material properties, thickness, and support systems. “Engineers use structural analysis to calculate stresses and strains, verifying that the façade can withstand them. Advanced software such as BIM and Revit aids in checking safety factors early
on, incorporating region-specific and design-specific data to guide decisions”, says Ar. Thareja.
According to Ar. Vineeth Kumar, Founder and Managing Director, Blitz Mind Studio, designing façades to handle environmental loads demands careful material selection and system design. For wind resistance, materials like reinforced glass, aluminium and steel are essential, while lightweight and flexible composite panels offer better performance in seismic-prone areas. Thermal expansion is managed by choosing materials with similar thermal coefficients and incorporating expansion joints to prevent cracking under temperature changes. A robust structural system with flexible connections absorbs wind and seismic forces, maintaining stability.
To validate load-bearing capacity, wind tunnel tests and simulations are performed. Anchoring systems must be designed to allow movement without compromising security, observes Ar. Vineeth Kumar. Insulated and ventilated double-skin façades help regulate thermal stress, minimising heat transfer. “Compliance with building codes ensures safety standards, while redundancy in design offers extra layers of protection. Optimising façade geometry and orientation reduces wind loads and thermal stress, enhancing the façade’s overall resilience,” adds Ar. Vineeth Kumar.

To ensure structural safety against environmental loads like wind and seismic forces, Ar. Anuj Sharma and Ar. Purva Saksena, Principal Architects and CoFounders, 656a Studio advises analysing wind pressure, selecting stiff materials, and designing proper anchorage. For seismic resilience, façades must accommodate building movements through flexible connections that prevent structural damage. Temperature variations demand materials with high thermal tolerance and sufficient expansion joints. Controlling deflection, ensuring material durability, and refining connection detailing are also essential for structural integrity. “Compliance with building codes and rigorous testing guarantee façade performance. Maintenance access is another crucial factor, supporting long-term safety and functionality”, points out Ar. Sharma.
Safety in façade design begins with analysing the building’s load-bearing
capacity and the façade’s integration with it, avows Ar. Prashant Kochhar, Founder & Principal Architect of LTDF Architecture + Interior Design. Material properties, thickness, and support systems are considered for stress management. In high-wind areas, adds Ar. Kochhar, façades must be designed to withstand strong forces, which involves considering building shape, orientation, and the surrounding environment. Wind tunnel testing evaluates wind impact, ensuring the façade’s resilience under extreme weather conditions.
In summary, façade structural safety is a complex, multi-faceted process that includes material selection, structural support, and strategic design for wind and seismic resistance, thermal control, and rigorous testing. By focusing on these aspects, architects ensure that façades are both visually appealing and resilient against environmental challenges, fulfilling their protective role effectively and safely over the long term.
INCORPORATING FIRE-RATED MATERIALS AND COMPARTMENTALISATION IN FAÇADE SYSTEMS
Ensuring fire safety across building façades involves the strategic use of firerated materials and compartmentalisation to prevent fire spread and meet stringent safety standards. Here, architects discuss key elements in enhancing façade fire safety, focusing on material choices, compartmentalisation, and code compliance.
“Designing fire-safe façades involves several key elements,” says Kumar. He points out the importance of using fire-
rated materials such as non-combustible cladding like aluminum composite panels and fire-resistant glass. “Insulation materials like mineral wool are often preferred over combustible options,” he adds. Kumar further explains that fire stops and cavity barriers are essential in multi-layer systems to seal voids and prevent fire spread. “Compartmentalisation is achieved by using fire-rated spandrel panels and creating both vertical and horizontal fire compartments to contain fire within specific areas,” he notes. He also emphasises the need for fireresistant detailing, with intumescent strips protecting joints and mullions and transoms constructed from fire-rated materials. “Smoke vents and fire dampers help control smoke, while compliance with regulations like NFPA 285 or BS 8414 is crucial,” Kumar concludes, adding that active systems such as sprinklers and water curtains provide added protection.
“To meet fire safety codes and limit fire spread, fire-rated materials like noncombustible cladding and fire-stopping

components are essential,” asserts Ar. Sharma and Ar. Saksena. They explain that compartmentalisation is achieved by installing fire breaks or barriers at intervals, particularly around windows, floors, and vertical spaces. “These barriers help contain the fire and prevent it from spreading across the façade,” they say. They emphasise that façade design must comply with local fire codes, ensuring that materials and systems are rigorously tested for fire resistance while maintaining necessary ventilation and drainage to support both functionality and safety.
“Fire-rated materials and compartmentalisation are critical to controlling fire spread across façades,” avers Ar. Shah. “At Creative Group, we use fire-resistant materials such as gypsum board, fire-rated glass, and concrete in our façade designs to slow the spread of fire, allowing more time for evacuation and firefighting.” He explains that compartmentalisation divides buildings into fire-resistant zones, which contain fires within designated sections and prevent their spread across the façade. “This approach, implemented in our large-scale projects, ensures compliance with stringent fire safety codes,” Ar. Shah adds, highlighting how this enhances both structural protection and occupant safety.
“It’s essential to select fire-resistant materials, such as cladding and insulation, to prevent the fire from spreading into the structure,” says Ar. Thareja. He notes that fire-resistant coatings and treatments applied to these materials further enhance their fire performance. “Effective compartmentalisation is also crucial,” he continues, explaining that fire breaks like barriers resistant to fire are installed within walls to control the movement of heat and smoke. “By limiting fire spread, these components provide additional time for safe evacuation,” he says, underscoring the importance of sealants and fire stoppers in containing fires across building envelopes.
“Fire-resistant components, including flooring, fire-stopping systems, and
compartmentation walls, are essential for containing fire,” explains Ar. Kochhar. “These elements are designed to withstand fire for specified periods, preventing spread and ensuring occupant safety.” He points out that façade systems and interior finishes are evaluated based on their response to fire, which determines their role in fire spread. “Perimeter fire barriers are crucial for stopping vertical fire spread between floors,” he adds. These barriers are positioned where floor slabs meet external walls, providing critical containment.
In conclusion, designing fire-safe façades relies on careful selection of fire-resistant materials, effective compartmentalisation, and adherence to fire safety codes. Together, these elements provide vital protection, safeguarding occupants and contributing to the resilience of building structures.
DESIGN STRATEGIES AND MATERIAL SPECIFICATIONS TO PREVENT WATER INFILTRATION
To prevent water infiltration and ensure effective drainage within façade assemblies, architects share key strategies focused on design elements, material specifications, and integrated drainage solutions. Maintaining the structural integrity and durability of buildings depends heavily on these approaches.
“Preventing water infiltration and ensuring effective drainage in façades are crucial for a building’s longevity,” says Ar. Kumar. He advocates for a layered water management approach, incorporating a primary weather barrier, a secondary drainage plane with waterproof membranes, and a ventilated cavity to manage water flow effectively. Material specifications play a significant role in this process; Ar. Kumar highlights the use of waterproof membranes, highperformance sealants, water-resistant insulation, and strategic flashing at transition points. Façade detailing is designed to direct water away from the

building, incorporating sloped surfaces, drip edges, and recessed joints. “Effective drainage systems, including weep holes, continuous drainage pathways, and subsill drainage, are essential components,” he adds. For joint and connection design, Kumar emphasises expansion joints and caulking, while thermal and moisture control is achieved through thermal breaks and vapor barriers to prevent condensation. Regular testing and performance verification ensures that the façade meets water-tightness standards.
To prevent water infiltration, Ar. Sharma and Ar. Saksena uses a rain-screen façade design with a ventilated cavity that allows moisture to escape, reducing the risk of buildup. “Weather-resistant barriers, sealants, and gaskets are crucial in sealing joints and penetrations,” they explain. Flashing is strategically integrated at critical points such as windows and doors, ensuring water is directed away from the building. Effective drainage systems, like weep holes and sloped surfaces, are incorporated to channel trapped moisture outwards, preserving the façade’s structural integrity and longevity.
At Creative Group LLP, Ar. Shah emphasises the use of overhangs, drip edges, and flashing to redirect water from building surfaces, which reduces the likelihood of water penetration. “We employ waterproof membranes and sealants at critical joints and vulnerable areas to create a robust barrier against moisture,” he says. Durable, weather-resistant materials like aluminum composite panels (ACP) and glass are integral to the design, chosen for their low water absorption and
resilience under extreme weather. Shah further mentions, “Proper grading and advanced drainage systems within the façade assembly manage water flow and prevent accumulation, ensuring structural integrity and façade longevity.” Notable examples of this approach include projects like the Prayagraj Railway Station and Kartarpur Corridor, where these strategies enhance durability.
Ar. Thareja points out that wall systems should be constructed to have a higher drying potential, which is essential for moisture control. When installing cladding, he recommends placing a water-resistant barrier behind it, especially when the siding material is installed over substrates like concrete or concrete masonry units, which can endure higher water exposure. “Water can be directed off surfaces by incorporating features like soffits, overhangs, and projecting elements,” he says. The durability of the structure also relies on long-lasting sealants and the integration of flashings in vulnerable areas to keep rainwater from entering façade joints.
Ar. Kochhar advises incorporating proper flashing around windows and penetrations to deflect water and prevent infiltration. “Waterproofing membranes behind the façade create an additional moisture barrier,” he notes, underscoring the importance of these elements. Ar.
Kochhar also suggests adding drainage channels or weep holes to allow water to escape from the façade, a key measure in ensuring efficient drainage in the façade assembly.
These design strategies and material choices collectively prevent water infiltration, safeguard building façades, and maintain the structural integrity of buildings. Proper detailing, durable materials, and effective drainage solutions are essential components in creating façades that stand the test of time.
ACHIEVING THERMAL AND ACOUSTIC INSULATION IN FAÇADE SYSTEMS
Effective façade design balances thermal and acoustic insulation while ensuring safety and compliance with building regulations. Achieving these properties requires a strategic mix of advanced materials and design elements that enhance energy efficiency, comfort, and overall performance.
According to Ar. Kumar, successful façade design for thermal and acoustic insulation hinges on using high-performance materials, careful detailing, and regulatory adherence. For thermal insulation, materials like mineral wool, extruded polystyrene (XPS), and low-emissivity insulated glass units (IGUs) are favored. Adding thermal breaks in metal frames and continuous insulation layers optimises insulation,

while ventilated façades help manage temperature changes and cut energy use. “Standards like ASHRAE 90.1 or EPBD are essential for ensuring efficiency,” he says. For acoustic insulation, Ar. Kumar suggests using mineral wool, acoustic boards, and laminated glass with sound-dampening interlayers, which help meet standards like STC or Rw. Safety is maintained with non-combustible insulation, fire barriers, and resilient designs that prevent moisture issues and withstand wind and seismic forces.
“To achieve thermal and acoustic insulation in façades, I use highperformance insulating materials like mineral wool or foam boards, paired with thermal breaks to reduce heat transfer,” says Ar. Sharma and Ar. Saksena. Acoustic barriers and double-glazing systems add soundproofing, while the materials are integrated to maintain structural integrity and comply with safety codes.
Ar. Shah emphasises that double-skin façades and insulated panels are highly effective for thermal insulation, as they reduce heat transfer and stabilise indoor temperatures, enhancing energy efficiency. “High-performance glass and composite panels are our preferred choices due to their insulating properties, especially important in areas with significant temperature fluctuations,” he says. For acoustic insulation, Ar. Shah recommends materials with sound absorption properties, such as acoustic panels and insulated glazing, to minimise external noise—a priority in environments like airports and railway stations.
Ar. Thareja highlights that materials such as mineral wool and natural cork are versatile for thermal and acoustic insulation. “Mineral wool is widely used for thermal insulation, known for its adaptability, sustainability, and contribution to structural performance,” he notes. Natural cork, a low-porosity
material, is another eco-friendly insulator used in buildings. Expanded polystyrene (EPS) is also common for façades due to its thermal properties and waterproof nature, making it suitable for floors, walls, and roofs.
Ar. Kochhar underscores the importance of air barriers in optimising thermal and acoustic insulation. “An effective air barrier prevents air leakage, significantly improving both thermal and acoustic performance,” he observes. Cavity wall construction filled with insulation material is another technique that enhances insulation. High-performance windows and doors with low U-values (indicating reduced heat transfer) and appropriate acoustic ratings are essential components of an insulated façade system.
Through innovative material use, thoughtful detailing, and compliance with safety codes, these strategies effectively prevent heat and noise transfer, ensuring façades contribute to comfortable, energy-efficient buildings.

Managing Risks and Enhancing Safety in Façade Projects
Expert Insights into Challenges and Solutions
IDENTIFYING RISKS IN FAÇADE PROJECTS
Façade projects face numerous risks due to complex interactions between materials, structure, and environmental factors. Dasun Siriwardena, DGM –Design & Engineering at Aparna-Craft Exteriors Pvt Ltd., notes that improper integration of materials and inadequate thermal or acoustic performance may lead to issues that only become apparent post-installation. Structural failures, often resulting from incorrect wind load calculations, can pose severe safety threats. Other issues like inadequate fire resistance and poor drainage can lead to water infiltration, while poor material choices may result in thermal expansion or visible deformation.
Façade projects play a critical role in both the aesthetic appeal and functional integrity of buildings, but they come with a range of challenges and risks. From material selection and structural integrity to environmental factors and safety compliance, façade systems must be meticulously designed and maintained to ensure long-term durability and occupant safety. Advanced technologies like AI-driven predictive tools, BIM, and simulation models are transforming risk management practices, making façade design and maintenance more effective and reliable.
In this article, industry experts provide insights into the complex challenges, especially in material choice, structural calculations, and adherence to safety standards, associated with façade projects, highlighting key risks and indicators of issues.
To mitigate these risks, advanced AI-driven Building Information Modelling (BIM) tools offer predictive insights by identifying potential weak points in the façade design before construction begins. Additionally, early-stage machine learning models help evaluate material performance, allowing design teams to suggest optimised alternatives. Siriwardena points out, common signs of façade problems, such as visible deformation, condensation, and discolouration from material degradation. These issues can be detected early using drone-based inspections, combined with AI image analysis for real-time diagnostics, reducing the risk of costly repairs or replacements in the future.
Façade projects come with inherent risks affecting performance, safety and durability
According to Mohit Sehgal, Head of Façade (North) at Rysn Infra LLP, façade projects face risks across several areas:
• Onsite delays can often occur due to various reasons such as bad weather or the availability of materials.
• Health and safety is vital at all stages of a project but especially onsite when the risk of an incident is often the greatest.
• Communication during the design process is key to avoid wastage.
• Risks post-installation are also present, such as corrosion.
• Replacement parts can prove difficult to find if the company no longer supplies them.
• If Building regulations are not met, companies risk prosecution.
THE ROLE OF EXPERT OVERSIGHT
Vishal Chawhan, Architect and Town Planner, emphasises the importance of engaging experienced façade consultants and contractors, noting that façade projects with specialised elements are
at high risk if expert oversight is lacking. According to Chawhan, having a façade consultant on board ensures the façade aligns with the architect’s vision and meets the intended specifications. An experienced contractor further reinforces this by executing the façade with precision, adhering to both design and safety standards.
INDICATORS OF FAÇADE ISSUES AT DIFFERENT STAGES
Façade-related issues typically emerge during two key stages:
1. Pre-Construction Stage includes design, detailing, and selecting an execution agency. At this stage, architects, structural consultants, and façade consultants must work in close collaboration to achieve a flawless design. However, challenges often arise when selecting the execution agency. In the Indian market, for instance, the emphasis on competitive pricing sometimes leads to performance compromises. The specifications are diluted, and critical elements such as fire stops and moisture barriers are sometimes sacrificed to cut costs. A team approach is necessary to ensure performance standards are maintained without bowing to price pressures.
2. Post-Construction Stage: Any compromises made during the preconstruction phase become apparent at this stage. Structural failures, leaks,
and visible cracks in the façade are primary indicators of underlying problems. By this point, the original team, including architects, structural consultants, and façade specialists, is usually no longer involved, leaving occupants to address these issues. Repairs often result in further erosion of quality, as pricing considerations dominate the repair process, and the involvement of expert teams is rare.
CRITERIA FOR SELECTING FAÇADE MATERIALS
Choosing materials for façades involves considerations for fire resistance, structural stability, and durability. Siriwardena highlights the role of advanced simulations and AI-driven analytics in predicting material behaviour under environmental stresses, helping teams select optimal materials.

Compliance with fire safety standards, such as EN 13501 and NFPA 285, is also essential.
Sehgal advocates for materials tested for fire resistance, with fire safety considerations extending beyond façades to include evacuation, detection, and suppression systems for a comprehensive safety approach.
Chawhan emphasises context-specific material selection based on factors like climate, occupancy, and seismic risks, requiring close collaboration between architects, structural engineers, façade consultants, and contractors to create a balanced and appropriate selection of materials tailored to the project’s unique demands. While there is no universally perfect choice, this teamwork approach enables the selection of materials that meet safety, performance, and aesthetic goals for each façade project.
ENSURING SAFETY IN HIGH-RISE FAÇADES
For high-rise buildings, façade systems must withstand wind pressures, heavy rains, and seismic forces. Siriwardena notes that computational fluid dynamics (CFD) simulations, supported by AI, help predict wind pressure distribution in urban settings. Virtual wind tunnel tests, incorporating real-time weather data, refine these models to ensure structural stability. For water and air penetration, parametric tests simulate rainfall and wind-driven water ingress to evaluate system resilience. Seismic stability is assessed through dynamic structural analysis software, which uses AI to simulate the performance of flexible joints and façade systems under varying earthquake scenarios based on regional seismic activity.
Sehgal stresses that façades in highrise structures must prioritise wind load considerations to avoid structural failures. Sehgal adds that façade engineering must prioritise wind load considerations, as high winds impose significant stress on a building’s exterior, potentially leading to damage or structural failure if inadequately designed.
Chawhan outlines a three-stage testing process for façade safety: virtual simulations, on-site mock-up testing, and post-installation evaluations. This rigorous approach ensures compliance with safety standards and long-term durability.
SECURE ANCHOR DESIGN IN FAÇADE SYSTEMS
Designing anchor systems for façades involves precision to manage environmental loads. Siriwardena explains that finite element analysis (FEA) helps visualise stress distribution across anchor points, while AI-driven predictive maintenance software tracks anchor
performance over time. During load testing, robotic arms simulate conditions like wind gusts and thermal expansion, enabling proactive maintenance and strengthening system resilience.
Load testing applies various force levels to test anchor reliability under different conditions. AI-enhanced robotic systems facilitate precise testing, while fatigue testing under extreme conditions forecasts the lifespan of façade anchors.
Real-time sensor data is used postinstallation for monitoring, with AI-driven predictive maintenance software that flags potential issues based on performance changes over time. During load testing, AIdriven robotic arms simulate environmental stresses like wind gusts, thermal expansion, and seismic activity. Fatigue testing under extreme conditions, supported by AI algorithms, predicts long-term wear and enables proactive maintenance.
FIRE-STOP SYSTEMS AND COMPARTMENTALISATION FOR SAFETY

buildings. Siriwardena shares that AIdriven fire simulation models are used to predict fire spread in different façade configurations, allowing for optimal firestop placement. Horizontal and vertical compartmentalisation, using fire-resistant materials like intumescent coatings, prevents fire from spreading across floors. Real-time sensors embedded in façades can detect early signs of fire, allowing for immediate response.
Sehgal explains that effective compartmentalisation minimises the “chimney effect,” where air pressure can push fire and smoke through a building. Building codes, such as India’s National Building Code (NBC) and Bureau of Indian Standards (BIS), mandate compartmentalisation to control fire spread. Following these standards, firestopping materials are strategically placed on separate floors, enhancing safety.
ENHANCED FIRE SAFETY THROUGH COMPARTMENTALISATION
Fire-stop systems & compartmentalisation are essential for fire safety in high-rise façades. Siriwardena notes that using fire-resistant materials and intumescent coatings within façades helps contain fire spread between floors. Real-time sensors in the façade detect signs of fire, allowing for prompt intervention and fire-stopping adjustments.
MAINTENANCE ACCESS AND SAFETY IN HIGH-RISE FAÇADES
For high-rise façades, safe access for cleaning, maintenance, and repairs is essential. Dasun Siriwardena highlights the use of Building Maintenance Units
(BMUs) equipped with AI features, which optimise cleaning schedules based on environmental conditions and wear patterns. IoT sensors embedded in façades monitor wear, reducing the need for manual inspections. Drones with AIpowered vision systems inspect façades, identifying areas needing maintenance without requiring workers to access dangerous spots.
MAINTENANCE PROTOCOLS FOR FAÇADE SAFETY
Mohit Sehgal emphasises that façade maintenance requires a detailed manual outlining cleaning protocols and safety procedures, tailored to each building’s unique requirements.
Key safety practices include:
1. Safety Harnesses and Anchors: Workers use safety harnesses connected to secure lines, regularly inspected for integrity.
2. Ascenders and Descenders: These devices allow safe vertical navigation and are used with safety lines.
3. Personal Protective Equipment (PPE): Essential PPE, such as helmets and gloves, shields workers from hazards like falling debris.
4. Weather Considerations: Maintenance activities are scheduled based on weather conditions to maximise safety.
5. Training: Proper training in equipment handling and safety protocols reduces risks.
6. Routine Equipment Inspections: Regular checks ensure that safety lines and harnesses remain in good condition.
7. Emergency Response Plans: Every operation includes an emergency
plan, ensuring quick responses to potential incidents.
8. Risk Assessments: Thorough risk evaluations are conducted before any maintenance work.
CUSTOMISED ACCESS SOLUTIONS
Architects and façade consultants work together to design access systems suited to each building’s specific requirements. Chawhan emphasises that while standard systems are available, custom solutions may be necessary to balance aesthetics, functionality, and maintenance needs. This collaborative approach ensures the façade is both attractive and accessible for routine upkeep.
MOVING TOWARDS SAFER FAÇADE DESIGN
Chawhan advocates for incorporating life-saving systems tailored for highrise façades, especially in areas prone to extreme weather or seismic activity. He suggests collaboration between regulatory bodies, designers, and technology providers to enhance façade safety standards, ensuring resilience against environmental and structural risks.

HeatCure’s nanotechnology-based solution, applied as a transparent layer, forms a protective barrier that insulates buildings year-round—keeping interiors
cool in the summer and retaining heat in winter.
Sanjay Mendiratta, Managing Director of HeatCure, expressed his enthusiasm about the expansion: “We are delighted to introduce HeatCure’s innovative nanotechnology glass coating to the B2C market, expanding our reach to consumers across India in major cities. HeatCure invites glass dealers, distributors, UPVC/Aluminium doors and window fabricators, and glass processors to join us on this revolutionary journey to protect the nation from scorching heat and to enable energy savings of 15 to 20%, thereby reducing our carbon footprint.”
He added: “With its remarkable ability to block heat and harmful rays while maintaining optimal visible light transmission, HeatCure offers a reliable and cost-effective solution for a cool and comfortable living environment.”
HeatCure’s nanotechnology solution is an efficient alternative to traditional heat-blocking methods like drapes, blinds, and tinted windows. The ultra-
thin insulation coating, which performs up to 15 years without maintenance, is ideal for a wide range of applications and does not compromise on visible light transmission. In addition to reducing UV damage to furnishings and interiors, it prevents heat loss during winter, making it a comprehensive, allseason solution.
Moreover, the energy-saving capabilities of HeatCure are a major draw. By controlling heat transfer, HeatCure can reduce energy usage by 15% to 20% during peak summer months. Customers have reported noticeable temperature drops of 2 to 9 degrees, depending on the amount of glass in their buildings, making it an attractive investment in both comfort and cost savings.

elZinc India: The Enduring Choice for Roofing and Cladding Solutions
Zinc has long been recognised as a dependable, corrosion-resistant, and visually appealing metal for roofing and cladding applications. When alloyed with titanium, zinc-titanium emerges as a prime choice for complex architectural projects, whether for new constructions or building renovations. Its exceptional strength, durability, and aesthetic appeal make it suitable for both roofs and façades, with a façade lifespan exceeding 150 years and roofs expected to last between 80 to 100 years.
One of the notable advantages of zinctitanium is its natural aging process, which varies based on environmental conditions. This metal can be successfully installed in diverse settings, including coastal areas, where traditional materials might struggle. Many examples of zinc roofing from over a century ago still exist, demonstrating minimal colour changes and requiring no special maintenance.
Zinc-titanium is available in a variety of sheet formats, such as width 1000mm, 1200mm, 1250mm, and the exclusive 1340mm offered by elZinc®. These sheets can be customized in length and thickness, ranging from 0.3mm to 3.00mm, with thicker materials often used for large-format façade panels. The ease of processing and remarkable malleability of zinc-titanium enable its application on various surfaces, from simple pitched roofs to intricately curved designs.
Architects can employ various techniques - such as split tiles, angular seaming, slats, and double seaming - to create distinctive textures and architectural identities with zinc-titanium laminates. This versatility allows for the shaping of architectural volumes using a single material, or utilizing different joining methods to emphasize specific building elements.
Zinc-titanium has a natural grey colour, enhanced by zinc carbonate patination that provides a warm hue without artificial colouring. This neutral tone
NIKHIL K JOSHI General Manager, elZinc
seamlessly integrates with both modern and traditional materials, making it ideal for use in historical districts. The elZinc® brand offers a Rainbow (Organic Pigment Finish) range, featuring pre-weathered substrates with natural mineral pigments. This unique finish not only enhances aesthetic appeal with colors like maroon, blue, green, black, and red but also boasts exceptional corrosion resistance.
Sustainable development is one of elZinc’s priorities; it is part of the philosophy that leads them to implementing innovative processes and products that respect the environment.
elZinc also provides customise option of organic pigment matching to nearest RAL shades which give advantage to Architect to use zinc in theme of the project.
For this reason, they have completed the Environmental Product Declaration (EPD) for elZinc Natural and the EPD for our entire range of elZinc Alkimi® pre-patinated products as part of the GlobalEPD program carried out by AENOR, an independent organisation of international prestige.

Transforming Fabrication with the Power of 5-Axis CNC Machines
As industries like aerospace, automotive, and architectural fabrication evolve, the demand for precise, complex, and customised parts is higher than ever. Enter the 5-axis CNC machine - a technological marvel that is redefining fabrication and manufacturing standards. Unlike traditional 3-axis machines, which can only move along three linear axes (X, Y, and Z), 5-axis CNC machines offer two additional rotational axes, allowing more intricate cuts and complex shapes to be machined in a single setup.
Key Advantages of 5-Axis CNC Machines
1. Enhanced Precision and Detail
The additional two axes allow for incredibly detailed and precise machining, achieving tolerances that were previously unattainable. In applications like aerospace or automotive, where exact measurements and smooth finishes are essential, 5-axis machines offer an edge. Their ability to maneuver around parts in multiple directions ensures consistent quality, even with intricate geometries.
2. Reduced Setup Time and Increased Efficiency
With a 5-axis machine, complex parts can be machined in a single setup, eliminating the need for re-positioning. This streamlines production, cutting down on both setup time and errors that arise from multiple fixture changes. For industries with high-demand production schedules, this results in faster turnaround times and optimised workflow.
3. Innovative Applications in Architectural Fabrication
In the realm of architectural hardware and facade systems, 5-axis CNC machines allow for the creation of bespoke elements that add unique character to fabrication. From complex joint connections to custom facade components, the possibilities are endless, enabling architects to push design boundaries without compromising structural integrity.
4.
Less Idle Time
A standout benefit of 5-axis CNC machines is their ability to perform multiple processes - such as cutting and machining - in a
single setup. This means there is no need to transport profiles from one machine to another, significantly reducing idle time, labour requirements, and worker fatigue. By combining processes, 5-axis CNC machines create a seamless and time-efficient production environment.
Realising the Future of Manufacturing
The advancements in 5-axis CNC technology are empowering manufacturers to meet today’s complex design demands with efficiency and innovation. As more industries adopt these machines, we are witnessing a transformative shift toward precision-driven, cost-effective, and sustainable manufacturing. For companies invested in remaining competitive, adopting 5-axis CNC technology could very well be the key to unlocking their full potential.

An Innovative Glass Façade Concept
Incorporating
Renson’s Integrated Sun Protection Screens
In the design of Hannibal (Belgium) new office, one principle stood out: the need for ample natural light. A glass façade emerged as the ideal solution; however, the challenge of managing sunlight’s heat and glare soon became apparent.
Sander Verhanneman, an architect at Rohm, highlights the importance of collaboration in architectural design. “Design is never the product of an architect alone,” he states. “For this new office, the glass façades on the first and second floors, conceived as a duplex landscape office with significant visibility to the outside, allow you to look straight into the treetops. Indoors and outdoors thus literally blend together here.” He continues, “With a glass front and rear façade, you can even see right through the building. That creates a vast openness and bathes the interior in light.”
To maintain a comfortable indoor climate, Verhanneman emphasises the need for effective sun protection. “For a curtain wall, external blinds are the most efficient way to keep it pleasantly fresh inside,” he notes.
Given the abundance of glass, the risk of overheating on sunny days is considerable. “For a glass façade like this — and by extension, for all windows — outdoor sun protection screens are the most efficient way to prevent it from quickly becoming unbearably hot inside on hot days,” Verhanneman explains, clarifying the decision to incorporate Renson screens. “This choice has consistently proven necessary in previous office projects. We often opt for dark screens in these cases because they offer more transparency. Even with the screens down, the view to the outside is thus fully maintained. What also played a part in the choice of Renson sun protection screens was that this would
also eliminate annoying reflections on computer screens.”
The integration of these screens was a significant undertaking. Jan Lein, the project manager, shares, “This project was quite a challenge. Visually, the front and rear façades are the same, but at the back, the Renson screens are nicely integrated with the façade. Architectural glass façades like these are never simple, and they require close monitoring from design to finishing.”
Verhanneman adds, “Our main concern was to be able to integrate those screens neatly and tightly into the curtain wall. We worked with Renson to find the most suitable elaboration. The new combination solution from Renson proved to be a hit for the parameters we had set. Whereas for curtain walls you used to have to make do with sun protection screens that were not fully compatible and whose coupling guides were simply screwed to the curtain wall profiles, here we were able to achieve a much tighter result that does not detract from the design in any way.”
Through innovative design and collaboration, Hannibal (Belgium) new office showcases a unique glass façade concept that seamlessly integrates aesthetics with functionality.

Rugged Metal Series from Aludecor
Merging Eras with Aludecor’s Newest Palette of Rugged Beauty with Solid Safety
Long before modern tools, metalsmiths shaped raw metal into functional works of art, leaving behind marks that told stories of craftsmanship and resilience. It’s this melding of raw beauty and durability that inspired Aludecor’s Rugged Metal series, where every surface reflects the timeless art created by the metalsmiths.
There are stories in those flickering lights, the calloused hands that knew the rhythm of fire and metal intimately; and with each strike, how he added to a legacy that spans centuries. Aludecor’s Rugged Metal series embodies the transformation of raw materials into timeless beauty, celebrating the craftsmanship of ancient artisans. Today’s architects are inspired to create enduring structures in both form and function. Each shade in the series, like Hammered Bronze and Oceanic Copper, reflects resilience and strength shaped by nature’s elements. Desert Bronze, with its weathered appearance, echoes the durability of materials that endure harsh conditions. These finishes impart a tactile quality to building facades, making them appear shaped by centuries of natural forces rather than modern manufacturing techniques.
The Unseen Guardian: Fire Retardant Technology
As much as the Rugged Metal series captivates with its artistic allure, it is also a hallmark of new-age facade design that is an ode to the metalsmiths. Beneath the surface lies a sophisticated layer of fire retardant technology, ensuring that these stunning panels do more than just elevate a building’s appearance—they actively protect it.
Aludecor’s Rugged Metal panels are available with FireWall A2 and FireWall B fire retardant cores, engineered to slow the spread of flames and offer vital extra minutes in the event of a fire. This technology is a commitment to creating facades that aren’t just visually compelling, but inherently safe. These panels, with their non-halogenated mineral cores, are designed to withstand
extreme heat, significantly reducing the risk of fire propagation, especially in high-rise buildings where the stakes are highest.
Beauty Forged in Resilience
In this series artistry meets engineering, which means the beauty of ancient craftsmanship is fused with modern safety standards. Just as metalsmiths of old shaped history with their hands, today’s architects can shape the future with these panels—crafting buildings that stand as symbols of both resilience and sophistication.
Redefining Urban Landscapes
As cities grow denser and buildings stretch higher, architects are tasked with balancing beauty and safety like never before. The Rugged Metal series provides a solution that does both—offering facades that are ruggedly beautiful, yet inherently durable. With the Quad Fusion Coating Technology, these panels offer a lead-free, environmentally conscious option that maintains its integrity in the face of wear and tear, guaranteeing a lifespan as enduring as their design.
Shape your next project with the legacy of the past and the innovation of the future. Shape it with Rugged Metal!
