EDITO NOTE R’S

Indian real estate is one of the biggest and world’s most recognised sectors, which is the second-highest employment generator in the country and contributes around 13% of the country’s GDP. As we come to the end of another financial year, the industry is looking forward to a profitable and better way ahead with a considerable increase in sales. Hopefully the year 2022-23 would be a year of recovery for the Indian real estate sector, especially the housing segment. According to the Knight Frank report titled 'Real Estate Outlook 2022', India's realty sector is showing signs of healthy growth in 2022. After a lacklustre pandemic period, the industry is on the path of recovery, driven by the large number of infrastructure projects announced by the government in the budget. The real estate sector is expected to reach a market size of $1 trillion by 2030 while contributing 18 to 20% to the GDP of the India's economy by 2025.

People are paying great attention towards the look and feel of the building facades and the builders are ready to spend a staggering amount to make the exterior look iconic and cozy. The cladding on a buildings give them shape and beauty, and the materials used on the facade help changing the paradigm of a building architecture.

The cladding of a building plays a very important role in projecting an iconic image, at the same time in protecting the building from all conditions like rains, wind, cyclones and fire. Cladding plays a key role in making a building sustainable. Right from aesthetics and durability to the life and installation method of the cladding material, everything has an impact on the sustainability quotient. A well-designed façade reduces the thermal bridges, and condensation of water vapour, and protects the building. Façade systems are expected to carry out several functions and perform in a variety of ways, such as structural integrity, durability, weather–resistance, acoustic insulation, thermal insulation, safety and security barriers, and more.

In this edition’s cover story, we have included insights from many experts on topics including trends in cladding designs, materials and installation. This edition also features interviews with a few experts who are pioneers in this field.

Other than the informative cover story and interesting interviews, this edition presents a gamut of new materials and technologies which would be of interest to the architects, builders and contractors. We hope you will enjoy reading this edition and will benefit from the industry insights. We look forward to your comments.

History of Cladding Materials

Alacquered wooden bowl dating back to 5000-4500 BC found at Hemudu, China is probably the oldest reference available on the origin of this modern-day technology.

The technique of combining fibre with resin was originally intended to provide waterproof protection to wood and bamboo. However, due to the extreme durability of such finishes, which is almost completely impervious to water and highly resistant to damage by acids or abrasion, numerous lacquered items have been unearthed in perfect conditions over the last many centuries. This shows the durability of the material. It is also fundamentally what is still done today in the production of wood/kraft paper based cladding materials like High-Pressure Laminates aka HPL.

But how these fibres are strengthened with resin has completely changed over this long period. Chemistry as well as the whole application process has changed. This is what makes one product different from another though all claim to be a combination of wood and resin. From Phenol-Formaldehyde to Melamine to Acrylic made the panels highly resistant to the UV radiation of the sun, a big plus to prevent colours from fading. These changes dramatically increased the design and colour possibilities for architects and made the material far more durable.

In 1969, a Dutch company called Trespa tested if its materials could be applied to the exterior of the building – and it worked! That’s how the journey of exterior cladding of buildings using laminated materials began and High-Pressure Laminate was borne.

In 2001, Westag introduced an acrylic-based solid surface that bends easily in the manufacturing process enabling it to fit on any surface seamlessly. The material provides a high level of colour consistency, is repairable and is non-porous.

In 2013, Fenix launched super matt laminates which are soft to touch, anti-fingerprint and make thermal healing of micro-scratches possible. Fenix has been launched in North America and Asia in 2020 by Formica.

Technology didn’t stop here. In 2020, new lignin-based resins that use 50% less phenol, making the materials more sustainable have been introduced.

Reducing our environmental footprint should be one of the key priorities of the cladding industry. Energy used as well as water consumed per square foot of cladding
