Measuring tools specialist Stabila establishes sales subsidiary in England as a clear commitment to the UK market For more than 60 years, measuring tools from the German manufacturer Stabila have been available in the UK. Over the years, a loyal and rapidly growing fan base has contributed to the UK becoming the second largest export market for Stabila and its permanently precise and robust spirit levels, tapes and since the 1990s lasers and electronic measuring tools. Ulrich Dähne, Stabila CEO, says: "Our strategy is to be present in our most important markets with an owned entity. Thus the time is right to establish Stabila UK Ltd. Having our own team of sales and application specialists will allow us to provide intensified support to customers. Stabila UK will work hand-in-hand with our distribution partners to develop strong and sustainable sales through enhanced and focused support in sales, logistics and training.” The brand will further step up its marketing activities. “The last four years we invested heavily in digital marketing. This sharpened the perception of our brand among professional users," emphasises Stabila CMO Holger Binder. "We can hardly wait to present our innovations personally to customers in the UK. In the year of the Brexit, this is a strong signal to our partners in the UK: we are closer to you than ever." ▴ Ulrich Daehne, CEO, in the new production hall measuring 1,400 m2 of additional space for the spirit levels production in Germany

Willmott Dixon awards £3.5m bathroom pod contracts to Offsite Solutions for Birmingham regeneration scheme Willmott Dixon has awarded two contracts totalling £3.5m to Offsite Solutions to supply bathroom pods for a £78m regeneration scheme in Birmingham. This use of offsite manufacturing will increase time efficiency by 30% as well as maximise the cost, quality, and sustainability benefits. The development, commissioned by Lendlease on behalf of Birmingham City Council, will create 430 apartments for sale and rent on the site of the former Birmingham City University Campus. The project is part of the wider £500m Perry Barr Regeneration scheme and will provide much-needed homes for local people in two four- to six-storey blocks that are due for occupation by 2023. Offsite Solutions is manufacturing 692 steel-framed bathroom and ensuite shower pods for the two apartment buildings. 2

BuildingProducts.co.uk • May/June 2021

The development at Perry Barr was designed by Corstorphine & Wright, as part of a wider residential development that will create new activity and vibrancy for the area whilst providing much-needed housing. Steel-framed bathroom pods offer limitless design options for largescale residential projects, hotels, and student accommodation. The wet areas to the pod walls and floor are fully tanked for long-term durability, and a composite ceiling panel in a matt paint-effect finish combines low maintenance with an enhanced appearance. The benefits of factory-built bathrooms include greater

certainty of completion on time and on budget, less time on site, and consistently high quality with advanced production processes and a robust testing regime in the factory. In the current pandemic, it is also easier to meet social distancing requirements when fitting out a confined space such as a bathroom in a controlled factory environment.

LETTER TO THE EDITOR

Garden office goals

Dear Editor,

Re: The Government’s ‘botched’ Green Homes – don’t neglect the challenge to motivate homeowners Ben Hayman is Chief Client Officer at Given, the agency for purpose-driven brands. Aside from the issues of too few installers, delays in grant payments and the need for a longterm committed programme, the Government must also address how it will encourage behaviour change amongst homeowners. Unlike electric vehicles, there is no pull towards home energy efficiency, or at least not one that is being presented in an accessible or desirable way. Smart meters started to go there, but efficiency is only part of the challenge.

William Woods, MD of IDF Aluminium Ltd, has recently embarked on an exciting new enterprise, manufacturing and installing modular garden office buildings, using Alutech’s BF73 aluminium profile system for bifold doors. Their unique design allows for the rooms to be taken down and relocated. Sister company, Aliwoods, will be taking care of sales and logistics.

We are going to need to change our heating systems, the way we use energy and where it is sourced from. If anything, people who do have the means to make positive changes in their homes (like installing renewable energy sources) have been burnt by previous Government changes to policy on grants and subsidies, and, as a result, many are now sceptical about the value of doing this.

With his new range of aluminium garden rooms, William is targeting the growing trend for home offices that have really found a market since the start of the pandemic last year, when companies were forced to adapt their working practices to allow more staff to work from home. And although restrictions have begun to be lifted, some of the changes to the way we live will undoubtedly remain.

The Government faces a huge communication and behaviour change challenge - we are all going to need both to use less energy and to invest in our homes more to make them energy efficient over the next 20 years, but consumers are not aware of this. The Government and energy companies must incentivise and stimulate us to change. They must demonstrate the value of making our homes green – showing homeowners how much they can save both financially and in terms of their carbon footprint. They must look for ways to talk about this at key moments to make it feel relevant e.g.: a review during house moves. And, perhaps most importantly, they must make all of this feel easy for people. Put simply, for most of us our homes are the biggest contributor to our carbon footprint, and no one knows it, let alone what to do about it.

BuildingProducts.co.uk • May/June 2021

William commented: “I started developing this concept a few years ago but have invested heavily in it more recently in light of an increased demand. There are three size options available, and all come fitted with a set of Alutech bifolding doors as standard. We began by installing three show models but have already started selling them and are currently in the process of updating our website.” If you would like an aluminium garden office pod, please call Aliwoods on 01376 510320.

Premier Modular awarded £9.8m project for new unit at St Peter’s Hospital Premier Modular has been awarded a £9.8m project for Ashford and St Peter’s Hospitals NHS Foundation Trust to build a 62-bed Priority Assessment Unit at St Peter’s Hospital in Chertsey. Main contractor Premier will be supported by strategic delivery partner Claritas Group. Due for completion by summer 2021, this fast-track building project will reduce the programme by up to nine months compared to in-situ construction. The speed of offsite manufacturing and fitting out will allow earlier occupation to support the increased demand for emergency care. Designed by BDP and delivery architects P+HS, the two-storey scheme will provide a new Priority Assessment Unit. It will be linked to the Emergency Department and will accommodate 62 patient bays, nurse stations, staff rooms, seminar rooms, laundry, clean utilities, and kitchenettes. The new unit will be

fitted with medical gases, datacomms, security systems, CCTV, nurse call systems, and fully integrated with the main hospital. The offsite solution has been engineered to maintain patient flows between the existing facilities and the new unit, with continuous level floors throughout. Externally, the assessment unit will be finished in vertical rainscreen cladding in shades of grey and brickwork to complement adjacent buildings. The building envelope has been designed to be highly thermally efficient to reduce running costs and carbon emissions, and the picture

Compact Automatic Entrance for Hospice Refurbishment Nightingale House, a charitably run palliative care facility in Wrexham, has undertaken a significant programme of upgrade. Improving accessibility into the facility, the main entrance now benefits from a double set of automatic folding doors from TORMAX, helping maintain the ambient temperature of the reception area by creating an internal lobby. With limited available space, the TORMAX folding door was the ideal solution with the four-leaf folding principle reducing the swivel range to just half that of a conventional two-leaf swing door. Requiring a minimum built-in width of just 1060-2260mm, the doors still offer a generous opening width that is suitable for all pedestrians and wheelchair users visiting Nightingale House. Implemented by Read Construction, phase one of the refurbishment has seen a modernisation of one entire wing of the building, including accessible toilets and showers, energy-efficient systems throughout, as well as the new reception area. Ideal for retrofitting during renovations such as this, the space-saving TORMAX folding door is an entirely prefabricated system that has been designed for ease of specification and installation.

As with the complete range of TORMAX automatic doors, the folding door is fitted with both vertical and horizontal threshold sensors, as well as a sensitive auto-reverse feature, which comes into operation when any obstacle is encountered during opening or closing

St Barts Hospital restored to its former glory with the help of secondary glazing During a 10 year ambitious plan, St Barts Hospital has seen the refurbishment of many buildings bringing them back to their eighteenth century glory. Others have been demolished to make way for new state-of-the-art facilities. Working closely with main contractor Skanska, the initial task was to provide acoustic insulation to eradicate external site noise and prevent ingress of dust from the demolition works into neighbouring buildings. 66 Series 46 fixed lights were installed in the wards, which proved a challenge as they had to remain fully functional at all times. The second phase was providing secondary glazing in ten of the operating theatres, ensuring they maintained the highest standards of sterility and controlled conditions. Series 41 side hung casements were installed allowing the complex combination of specially developed power roller ‘privacy’ blinds, together with ‘blackout’ blinds, which were deemed essential in order to contain lasers used within the theatres. Selectaglaze is the leading specialist in secondary glazing, established in 1966 and Royal Warrant Holder since 2004. It boasts a wealth of knowledge and a range of extensive products to suit all projects from Listed properties, to new builds. The company offers a wide range of tested products covering acoustic and thermal performance as well as protection against intruder and blast mitigation. A free technical advisory service is offered and RIBA approved CPDs are available to architects and designers.

Government’s Residential Property Development Tax will reduce the number of build-to-rent schemes Investors building properties for rental may now pull out, say tax and advisory firm Blick Rothenberg Heather Powell, a partner at the firm and Head of Property said: “Governments plans to raise £2bn from residential developers to pay for the cladding crisis via a tax on their profits and will cause many investors to think again. “Funds will be raised in two ways, a tax on their profits, to be called Residential Property Development Tax (RPDT) and a levy charged to all developers building new high rise residential blocks. “The RPDT is to be payable on profits generated from residential development in excess of £25m, but no deduction will be allowed for any interest and finance charges when calculating the profit to be taxed. As interest is a major cost for many developers the tax could push a profitable development into a loss.” 12

DEBATE

A budget with no mention of Brexit?

Building Products looks at what the Spring Budget means for the sector

as there ever been a more anticipated Budget? Perhaps. But it is difficult to argue that this was not one of the most significant for the country following the annus horribilis that was 2020. We now look forward though and to review what the Budget means for those in the Building Products space, we spoke to four sector leads to gain their opinion and insight.

Brendan Sharkey, Head of Construction and Real Estate at MHA Although there was much hyperbole over what to expect from the budget, the reality was a generally positive outcome for the construction and real estate sector. The measures announced showed that the Government is serious about its wish to increase home ownership and the number of homes built each year. The phasing out of the Stamp Duty Land Tax reduction over 12 months maintains the momentum for new builds and the refurbishment or development of existing housing stock, as does the 95% Government-

backed mortgage. After the Budget enquiries went up on all online real estate portals and property websites. However, although demand has been stimulated, there may not be the enough stock on the market.

in six-and-half-years. This was not just house building, but commercial construction and civil engineering. The seeds for further good news in the months to come are set to bear even more fruit.

In addition, the super-deduction for capital expenditure should be a stimulus for further investment in the construction sector, including in offsite manufacture and modern methods of construction.

Looking further ahead at the proposed increase in Corporation Tax from 19% to 25% for profits over £50,000 in two years, some commentators already think this may not happen. In simplistic terms remuneration will be allowable as a deduction, but the tax rate payable by an individual is likely to be higher than the rate of Corporation Tax. Consequently, the retention of funds in a company will cost more but there will still be reliefs available for capital investment and research and development so maybe investing in one’s business is the order of the day.

The commitment to £27bn for infrastructure, the continued development of HS2 and the confirmation that this rail line will be extended from Birmingham to Crewe all contribute to creating a feeling of optimism in the sector. Likewise, freeports should involve additional spending on infrastructure and capital. There are clearly ‘green shoots’ appearing in the sector so now it is the opportunity to return to profitability and repair balance sheets. The IHS Markit Construction Purchasing Managers Index for March registered 61.7 from 53.3 in February (anything above 50 indicates growth), as construction output increased at the fastest rate

Paul Hamer, Chief Executive of Sir Robert McAlpine A National Infrastructure Bank, with an initial capitalisation of £12bn to invest in an array of public and private projects, is very good news indeed for construction and the

country. The Government has an intent for 'Build Back Better' to be much more than a slogan and to make good on the commitments they made last summer. What is more, in locating the Bank in Leeds, the Government has sent a powerful message that it appreciates the need to level up areas outside of London. Crucially, the Government has recognised that investment in upgrading or maintaining existing infrastructure is vitally important. For one, given the arterial importance of Britain's roadways, any investment intended to support the transport of

freight is to be welcomed. This was a vital component of last summer's spending plans, so hopefully we will see this continue. The planned 'super deductions' for businesses investing is further good news and could see innovation accelerate right across the sector as firms commit money to new technologies and sustainable construction solutions. The positive ripple effect could be significant, and we will be looking closely at how this may benefit our business and future projects. It is difficult to predict whether the Government's budget strategy

will create further private sector investment as hoped, but in the immediate term, today's budget alongside the revised OBR [Office for Budget Responsibility] economic forecasts is encouraging.

SPRING BUDGET

DEBATE A recovery built on investment is absolutely the right approach. When we look to investment in people, the doubling of incentives to support businesses taking on apprenticeships is welcome, but it does not fully reflect the value that business delivers through apprentice schemes. It would have been good to hear this go further and guarantee that the Apprenticeship Levy is ringfenced and adapted to support further investment in the infrastructure needed to deliver quality apprenticeships. The focus on additional support for traineeships is also encouraging and we will be looking to ensure this is targeted at creating jobs in our sector. It is crucial that we pull out all the stops to support businesses here as the immigration policy has the potential to hamstrung parts of economy if we do not effectively support the huge scaling up in training that is required to offset. Extending and adapting the stamp duty holidays should ensure that the recovery in the housebuilding sector does not come to a hard stop and combined with mortgage guarantees supports continued investment. It was encouraging for our sector to hear that the Chancellor used construction as the exemplar for investment in describing the new Super Deduction Scheme. This scheme, which goes beyond full expensing and allows businesses to reduce their tax bill by 130% of the cost, sounds like a positive move and we look forward to fully understanding the scope and type of investment that can be supported. Announcements around this, carrying back business

BuildingProducts.co.uk • May/June 2021

losses and the re-emphasis of the importance of R&D tax credits help, with the time lag soften the blow of what on the surface are steep increases in corporation tax. The National Infrastructure Bank and focus on Regional Growth and Free Port areas again should encourage investment and reconfirms that Government is committed to investing in vital infrastructure.

It is important to note however that given some of these may be ‘re-announcements’ of existing commitments or allocations of existing funding, the full interpretation of today’s announcements will take longer to analyse.

It was also good to hear the intrinsic link being made between economic and environmental development, signified most clearly by incorporating environmental sustainability and the transition to net zero within the remit of the Bank of England. One real disappointment is that the Budget was silent on Building Safety Aspects and we still seem to be floundering around this issue that is very much at the core of how we look after people within our society, but it was also a shame that we did not get recognition of the cash impact of Reverse Charge VAT, an extension to the deferral scheme would have helped many businesses keep their head above water. It is a shame too that, given the extended period of lockdown, the Chancellor did not extend the interest free period on some of the loan packages (e.g. CBILS) that have supported businesses through this difficult period. Peter Caplehorn, CPA Chief Executive The Government announced its Spring Budget, with a series of policy and funding announcements relevant to CPA members and industry.

We knew beforehand that the Budget would focus primarily on the recovery from the virus and job protection; therefore, we are not surprised that construction per se was not a major beneficiary today. Still, members will note the trial of ‘super deductions’ for business investment; extension of the stamp duty holiday; further detail on a UK infrastructure bank and commitment to boosting science and innovation, as well as a doubling of incentives for apprenticeships. We must also point out our disappointment that there was little in the Budget on energy-efficient retrofit of the existing housing stock, given the importance that Government has placed on Net Zero – particularly in the year of COP26 – and especially given the concern over Government’s delivery under the Green Homes Grant. 

INTERVIEW

MD In Focus:

DARREN WATERS Managing Director of Ibstock Concrete and Ibstock Kevington

or this feature, Building Products talks to an MD or CEO to find out about their working day and plans for the future.

CAN YOU TELL US ABOUT YOUR BACKGROUND? I recently joined Ibstock from Tyman plc, a leading supplier of components to the door and window industry, where I held the position of CEO for the UK trading division.

largest brickwork specialist shape and masonry fabrication company. HOW HAVE YOU SEEN THE SECTOR CHANGE OVER THE YEARS? Over the last year, the construction industry has undergone one of its most challenging periods to date, with COVID-19 and Brexit having a significant impact on manufacturing output, corresponding inventory levels and, as a result, project completion rates.

WHAT DOES YOUR ROLE AS MANAGING DIRECTOR ENTAIL?

To overcome these issues, manufacturers have had to look internally at the role they play within the supply chain, to ensure customers have access to the necessary products, when they require them.

As the new Managing Director of Ibstock Concrete, I will be responsible for the building products, flooring, and infrastructure businesses, which includes the Forticrete, Supreme, Anderton and Longley brands.

This created a requirement for closer collaboration throughout each stage of the supply chain, facilitating successful communication to aid Britain in getting back to building safely and efficiently.

Since joining the business in April, I have been working closely with each team to understand the complex needs of our extensive customer base and identify how Ibstock Concrete can support them in successfully fulfilling the most demanding project requirements.

Throughout this difficult period, Ibstock has explored how it can work smarter and harder to become an even easier company to do business with. Consistent and effective communication lies at the centre of this success.

Prior to that I worked for Tarmac and RMC in a number of senior leadership roles in concrete, mortar, and cement.

This includes the merchant, housebuilder, rail, and infrastructure sectors. With our products reaching every corner of the industry, it’s imperative that we consistently deliver the same standard of customer excellence and continue to set the pace for innovation and product development. I am also Managing Director of Ibstock Kevington, which is the UK’s

"FROM PRECAST CONCRETE ROOF TILES, TO FENCING POSTS AND FLOOR BEAMS, OUR COMPREHENSIVE BUILDING PRODUCT PORTFOLIOS ARE CONTINUOUSLY EVOLVING TO ENSURE THEY MEET THE LATEST DEMANDS."

Improving this even further and exploring alternative ways of working with our customers will be a key priority for myself and the team throughout 2021. WHAT TYPE OF PROJECTS ARE YOU TYPICALLY INVOLVED IN? Ibstock Concrete’s heartlands lies within the housebuilding and merchant sectors, having supplied these industries with the highest quality building products for over 90 years. From precast concrete roof tiles, to fencing posts and floor beams, our comprehensive building product portfolios are continuously evolving to ensure they meet the latest demands. This includes improving the design, manufacture, and supply of our products to support our customers in effectively increasing on-site productivity and performance, whilst simultaneously minimising associated cost, resources, and environmental implications. However, Ibstock Concrete is also experiencing rapid expansion throughout the infrastructure and rail markets, as Anderton Concrete continues to implement significant investment in its bespoke and standard concrete offering to support civil engineers and construction professionals in receiving large volumes of high-quality precast concrete, in the shortest lead times possible. Within Ibstock Kevington, we are also seeing increased demand for our Mech Slip solution, which is the most comprehensively tested and certified non-combustible rainscreen cladding. Cont.

INTERVIEW

DARREN WATERS

HOW IS TECHNOLOGY IMPACTING THE SECTOR? If we accurately harness technology, it has the ability to significantly improve the construction industry, by enabling manufacturers such as ourselves to make every step of the design, specification, and installation processes easier for our customers. For many years, the construction sector has played catch up when compared to many other industries, however, latest advancements in technology, such as visualisation software, are enabling us to effectively engage and connect with our customers like never before. By adopting and continuously improving these tools, we can support professionals in physically seeing how their project will look if they specify our products, from the convenience of their own office, whilst also offering the ability to instantly demonstrate the associated cost, time, and productivity benefits. HOW IMPORTANT IS SUSTAINABILITY TO YOUR BUSINESS? As a leading manufacturer situated at the heart of building, Ibstock is committed to driving sustainability through continued investment in its people and the planet. In January this year, Ibstock plc became the first building products manufacturer in the UK to procure 100% of its electricity from renewable sources. We have also just announced a £60m investment in a brand-new brick factory in the West Midlands, which will be the first net zero carbon brick-manufacturing facility in the UK. This achievement forms part of its Sustainability Roadmap 2025, which communicates clear targets for the business under four core objective areas: customers and suppliers, people, environment and communities. Ibstock is committed to the continuous development and enhancement of its precast concrete products to not only minimise their environmental impact, but support construction professionals in reducing the overall carbon output of the final build. For example, Forticrete, our roof tile business, has substantially reduced the embodied carbon within its popular Gemini® tile range, by using low carbon cement to provide a more durable and environmentally20

friendly tile, that delivers increased longevity and minimises product waste. Every aspect of Ibstock’s actions are considered from the perspective of sustainability, and to further support this, a number of specialists are currently being recruited to help Ibstock manufacture more sustainable products and solutions that support biodiversity. WHAT WOULD YOU SAY ARE THE BIGGEST CHALLENGES FACING YOU AS A LEADER? In the 10 years that I’ve been out of the sector, apart from the structural changes in ownership, heavy building materials hasn’t changed a great deal, while the world around us has. Successful B2C businesses like Amazon have set new benchmarks for customer service and changed the way that people buy. We need to think differently about how we engage with our customers to provide them with the information they need and reassess our service proposition. This will require a shift in mindset for traditional businesses, but I believe it’s an area where Ibstock can lead.

"WE HAVE ALSO JUST ANNOUNCED A £60M INVESTMENT IN A BRAND NEW BRICK FACTORY IN THE WEST MIDLANDS, WHICH WILL BE THE FIRST NET ZERO CARBON BRICKMANUFACTURING FACILITY IN THE UK."

ARE YOU OPTIMISTIC ABOUT THE FUTURE FOR THE SECTOR? The outlook for the UK construction industry over the next few years looks positive, with significant investment in infrastructure projects and the growth in demand for new housing set to continue. Whilst the last 18 months have been extremely challenging for the entire sector, the current mini housing boom, created as a result of the Government’s Stamp Duty Holiday and the Affordable Housing Programme, has positioned the industry as playing a core role in reestablishing the continued economic success of the nation. The infrastructure sector is also extremely buoyant, with the value of projects starting on site averaging at over £5.6m per month during the first quarter of 2021, a 16% increase against the preceding three months and 9% higher than a year ago, according to latest research conducted by Glenigan. The continued investment Ibstock has undertaken over the last 18 months places us in an extremely strong position to support this increased rate of building, and I look forward to working with my teams this year to accelerate this even further. 

DEBATE

2021 IS GOING TO BE A GOOD YEAR FOR CONSTRUCTION TECHNOLOGY

echnology is changing the way we construct residential and commercial buildings and think about urban spaces, with architects and specifiers now able to consider a much wider selection of products that can improve building efficiency and performance. To find out more about this space and to see how the pandemic has impacted innovation, we spoke to a group of leaders to get their views.

TO START OFF THE DEBATE, HOW WOULD YOU ACTUALLY DEFINE SMART BUILDINGS? Dan Grimshaw – CEO, Beam Development: "For me at the most basic level, smart buildings are about having the ability to manage your heating system for example, but with more control per floor, or per room. Systems like the Nest Thermostat allow you to program your thermostat’s schedule which can be controlled via your mobile and that can integrate with other smart devices in your property. "Next up are Building Management Systems (BMS) – computer-based control systems installed to control and monitor a building’s mechanical and electrical equipment. These can be programmed to be ‘smart’, depending on the factors you want to adapt to – whether it's the external temperature, the weather, or how many people are in the house, or the usage. "At the other end of the spectrum, smart buildings are being constructed off-site with renewable energy already in them to automatically control heating, ventilation, air conditioning, lighting, and security. Systems work by managing the electricity you generate with the electricity you take from the grid; that energy then goes into the ‘brain’ of the house which manages your devices. It could mean your washing machine comes on

when energy is at its cheapest, or when you've got a surplus, and once that’s done if there is energy left over, it feeds that electricity back into the grid. The aim of the system is to maximise user comfort while minimising energy consumption." Birgit Linnamäe – CEO, Kodasema:"First of all, a smart building needs to be smartly built. Today, this can mean a factory built house. It leaves a smaller footprint in terms of transport, CO2 emissions, pollution, builder injuries, construction waste and urban noise.

▴ Ian Marson

▴ Birgit Linnamäe

"With smart buildings and dynamic spaces, councils and developers can create smart cities. When cities take the lead in creating people-centric environments – for example simplifying permits for micro homes and communities, a greater number of people will be happier and healthier. Micro homes can be an integral solution to the severe housing shortage." WHAT TRENDS ARE YOU SEEING AROUND HOW TECHNOLOGY IS CHANGING THE WAYS BUILDINGS ARE MADE AND FUNCTION?

"Smart building design contains everything necessary in the space, and its function can be changed quickly, resulting in dynamic urban spaces. Buildings are smart if they can be moved or repurposed with ease to provide communities with more flexibility.

Dan Grimshaw: "The tech and the kit in the renewables sector are becoming more effective and more affordable. The trend is moving towards more modern methods with off-site construction which is likely to bring about a big change in the building process.

"From films to transport, people prefer on-demand today. Accommodation and office space is undergoing this same shift and a city moves where users want it to. I predict our future cities will be polycentric and neighbourhood-driven, with culture and services at your doorstep, resulting in less cross-city commuting.

"A factory environment like this is more likely to push ideas and innovation. However, such methods are not really being pushed on the traditional side by the big construction companies in the UK at the moment, though things are beginning to change.

"You might remember smart buildings from early sci-fi movies having flashing switchboards, but we see that our clients are drawn to minimalism. There is already too much data noise around us. To relax our minds, we prefer to have simple on/off buttons, not having to fuss around with complicated user interfaces (ULS). Hannes Tamjärv – Founder, Kodasema: "Kodasema’s starting point nearly seven years ago was to design spaces that allow to cut the energy consumption in housing whilst innovating the construction industry. Small living spaces often automatically mean less energy is required, leaving a smaller footprint.

"SMART BUILDING DESIGN CONTAINS EVERYTHING NECESSARY IN THE SPACE, AND ITS FUNCTION CAN BE CHANGED QUICKLY, RESULTING IN DYNAMIC URBAN SPACES." Birgit Linnamäe

"Mechanical Ventilation with Heat Recovery (MVHR) systems are becoming much more standard, especially in new houses. MVHRs extract warm, damp air from the home and draw in fresh air from the outside. The extracted air is passed through a heat exchanger to recover the heat before being expelled outside. Meanwhile, cool, fresh air from outside is passed through the exchanger where it is pre-warmed before being pumped into the property. "Meanwhile, NOx filters – metal boxes that house an activated carbon filter stage where the air that is drawn in by the MVHR unit passes through the activated carbon filter panel reduces contaminants such as traffic and exhaust fumes – are increasingly popular to create a fresh air environment inside the house. "There are also trends towards virtual, computergenerated intelligent personal assistants, like Amazon’s Alexa, where things can be turned on or turned off or programmed or set up to happen." Cont.

way back to the office, will be critical in retaining existing occupiers and attracting new ones. "Demand for truly innovative, technologically advanced workspaces, where people can interact with facilities management has increased and will go further to help future proof business environments. However, all important will be how businesses use the data capture of smart buildings as a tool for analysis and the development of new systems and processes. "This will also enable the implementation of a long-term intelligent building strategy that will far outlive the useful life of any specific technology. A successful strategy is one of communication, between the systems and the people monitoring them, and then using the data collected for its highest and best purpose. ▴ Hannes Tamjärv

▴ Roy Danon

Birgit Linnamäe: "Construction is the biggest industry in the world, and yet it has not been performing well. The ecosystem represents 13% of global GDP, but construction has seen a meagre productivity growth of 1% annually for the past two decades. In 2017, the McKinsey Global Institute highlighted that the construction industry needs to improve productivity by 50 to 60%. Using technological advances is the best way to achieve that. "Moving construction jobs to off-site prefabrication facilities is one step towards enhancing efficiency. In Scandinavia, 45% of housing is now being built using off-site manufacturing and the permanent modularconstruction market share of new North American real-estate construction projects grew by 50% from 2015 to 2018. "Further, BIM enables more precision during planning and implementation in construction. Building technologies today need to consider the overall sustainability of the building, planning, and permitting procedures as well as the carbon footprint. One of the aspects is using more lightweight materials, such as replacing concrete with timber or other modern methods of construction (MMC)."

"In the future this could give you the ability to ‘tell’ your smart office via an app that you’re on your way during your morning commute, enabling you to select the type of space you will need to effectively work that day and even order your coffee to be at your desk when you arrive. "Smart buildings should be viewed as a long-term strategy to better understand the relationship between the built environment and its occupants and is not exclusive to offices and other workspaces. Increasingly we are seeing technology used in domestic environments, such as retrofitting of systems for use on the Internet of Things (IoT), with sensors to control heating and lighting, through to smart appliances. "Investing in smart building construction from the initial design stage or, where this isn’t possible, retrofitting existing buildings with these new technologies, can help to save on operational costs, increase building efficiency and play an important role in supporting the reduction of harmful emissions." IS INNOVATION BEING ACCELERATED BECAUSE OF THE PANDEMIC?

Ian Marson – Head of Construction, EY: "Smart buildings provide a framework to allow companies to capitalise on digital innovation. They allow owners to better understand occupiers, their needs, and behaviours, with the goal of enhancing well-being and productivity. "The global pandemic has shone a light on the need for occupiers to be smarter in the way they utilise their working environment, creating a more flexible and engaging space in which people can operate. COVID-19 has accelerated innovation and continued development in these areas and, as workers make their

Dan Grimshaw: "The reality of the past year, with more and more of us working from home due to the pandemic, is focussing people’s minds on the environment they live in. We are seeing more people concerned about ventilation with a growing antipathy towards breathing in stale air – with more people in the house – or pollution from vehicles if you live near a busy road;

having a constant climate and environment has an impact on experience and well-being and helps lift the spirt and the mind." Birgit Linnamäe: "Kodasema has seen a growing interest in prefabricated housing during the pandemic. People look for houses with separate safe entrances, stand-alone ventilation, using less energy as well as space. Our long-term health, well-being, and performance are directly dependent on the quality of life that our buildings provide. "Quick and easy innovative developments with turnkey, plug-n-play micro housing solutions are important to make cities more liveable. A wonderful solution is in creating pocket neighbourhoods of small-footprint homes, arranged around a shared common area. This provides people with a feeling of safety and belonging, creating a higher sense of happiness. Kodasema created such a community in Tallinn Old City Harbour – KODA Park, recently sold to investors. "It is a challenge for the local Governments to find ways of simplifying permitting for temporary and micro housing concepts, but there is so much to gain rather than to lose. And there should be a broader debate and raising regulators’ awareness about the need for change." Roy Danon – CEO & Co-Founder, Buildots: "Without a doubt, the pandemic accelerated the use of technology in construction. We could say the industry was at a tipping point and the pandemic was the final nudge. Applications such as Teams and Zoom are household names. Tech has been hugely impactful, and because of this people have become more tech savvy.

GOING BEYOND BUILDINGS - DOES URBAN PLANNING NEED TO CHANGE? Birgit Linnamäe: "Urban planning also needs to be smart(er). In the UK, car parks in shopping centres and near railway stations can obtain dual purpose – allowing parking cars and yet enabling elevated KODA houses above. This could solve many problems the Councils are facing, the biggest being relieving the housing shortage, but also reducing commuting time to city centres. "When housing is transported volumetrically and installed within hours on-site, efficiency is automatically increased, with minimum disruption to the community. Speed of lead times as well as minimal work on-site of holiday and residential parks, are increasingly important criteria for homeowners, developers, and the public sector – for quick and easy housing solutions. "Regarding proposed redensification by councils in the UK, Homes England is doing a great job bringing different parties together to help bring such projects to life. An excellent example of an innovative municipal initiative has been set by the German City of Hanover, the Capital of Lower Saxony in northern Germany, who has taken the leading role among big European cities installing micro homes for rent after having arranged permitting, configuration and contracting all within six months only." 

"Construction has been regarded as second only to agriculture as the slowest adopter of tech, yet this is changing. A lot of heads have been turned. Key stakeholders who were once sceptical are now recognising the huge benefits, especially the difference tech is making to productivity and collaboration. "I predict that it will be a good year for construction tech. BIM adoption is growing year on year, and this is something that will continue in momentum during the coming months. "The biggest question marks will be in terms of the return to office working, particularly in big cities. So many buildings are vacant. Is that going to slow down commercial projects? Perhaps. This is a consideration we should be mindful of, whether it happens is a separate thing entirely."

Fixing innovation streamlines installation of flat roofs with tapered insulation

oofing and cladding fastening systems specialist EJOT UK has developed a new mechanical fastener solution to help installers save time and money when installing flat roofing with tapered insulation.

The JBS-R/EcoTek combination brings together a high performing concrete screw (JBS-R 7.5) with a high-quality telescopic tubewasher (EcoTek) to provide a fixing solution that is adjustable to fit the required depth of insulation. It is universally suitable too,

providing a solution for mineral fibre, EPS, XPS and PIR tapered insulation. As the illustration shows, this makes the fastener suitable for any insulation depth of between 70mm and 500mm, using fewer fastener/ washer combinations than current mechanical fixing approaches. This can easily reduce fastener use for a slope insulation of 120 to 260 millimetres by as much as 25%, subject to the application, a site survey and pull out test. Installation is easy as only one embedment depth is needed

whatever the insulation thickness and adjustability is achieved thanks to the innovative way that the EcoTek tubewasher is driven into place using a custom tool with the fastener already in place. And where the insulation is especially deep, installers can simply use EJOT’s flanged A-cone and extension – this helps to eliminate the awkwardness of drilling deep using standard SDS drills. Kevin Rackley, Product Manager for Flat Roofing Fastener Systems at EJOT UK said: "Cut to falls insulation is used in around a third of all the flat roofs installed in the UK today so it is important that we innovate and find ways to make this approach as easy and cost-effective as possible. “This is why the JBS-R/EcoTek fastening system offers huge potential to make a difference for installers. Given the need for only one set embedment, using JBS-R/EcoTek means installers don’t need to think about the usual variety of product combinations on site – the job can be done easier and quicker with an all-round better result. “And using this new EJOT product combination also simplifies ordering and stockholding for contractors with no need to source a variety of different concrete screws and stress plates.”

OPINION

WAS THE LIGHT BULB THE DEATH OF MODERN CONSTRUCTION?

he invention of the light bulb was one of the worst things to happen to the construction industry, says chartered engineer Lee Marshall, Managing Director of leading sustainable building services company, Viridis. Here, he explains why.

There is no disputing the economic and social impact that the arrival of the light bulb had on our lives. It allowed factories and businesses to run into the night, revolutionised our homes and social lives, and allowed us to travel safely in the dark. So much has been made possible with artificial light. 28

BuildingProducts.co.uk • May/June 2021

However, in my view, it was also one of the worst things that could have happened to the world of construction as it made everything smaller. It led to the death of large, airy windows that let natural light flood in. Before the light bulb was introduced in the nineteenth century, properties were built to let in as much daylight as possible, thanks to the astronomical cost of oil lamps and candles. In the post-war era, ceiling heights in properties really came down and windows became smaller as we could light our homes artificially. This continued into the housing boom of the 1950s and 60s and in the social housing growth of the 1970s and 80s. With the advent

creative. For example, there is a huge waste of space and volume with traditional triangular roof trusses - you are probably losing about 25%-30% of the building for nothing. We could push into that volume. By lifting the first floor a few hundred millimetres and raising the bedroom ceiling further into the loft, you could push up the space by about ten feet and put in bigger windows, create some nice features such as vaulting, and reduce the energy consumption.

We could also redefine our living spaces by changing the layout and geography of a house, which is normally dictated by the position of the stairs. If we put the stairs at the back of the property, then all the downstairs rooms could be at the front of the house. Would you even need windows at the back? It could be a north-facing wall that is timberframed and well-insulated. Then you could have bigger windows on the front. The bedrooms would be front or south-facing, making the property a more rectangular shape, and you would have a larger, southfacing front garden that is accessible from both the kitchen and living area. If an entire neighbourhood is organised in this way, it creates a sensitive layout that gives privacy but maximises daylight – reducing the reliance on artificial light. I’ve been working in this industry for 20 years and understand it takes time to turn things around. Many in the building industry have convinced themselves that people want a square house with a big roof and there is a reluctance to break the mould.

of LED lighting, our homes are more energy-efficient to run – not to mention warmer thanks to modern insulation and double glazing – but we haven’t updated our construction methods. This needs to change. We need to not only start building better but also change our approach to how we build. I firmly believe that if you have a good, sustainable housing offering that is scalable then there is an opportunity to transform the market, but designs need to be more

"I FIRMLY BELIEVE THAT IF YOU HAVE A GOOD, SUSTAINABLE HOUSING OFFERING THAT IS SCALABLE THEN THERE IS AN OPPORTUNITY TO TRANSFORM THE MARKET, BUT DESIGNS NEED TO BE MORE CREATIVE." Lee Marshall

Under current regulations, a window area must equate to approximately 20% of the floor area to allow a small amount of daylight. If we said it should be increased to 40%-50% and the minimum ceiling height should be three metres, it would transform how we live and improve health & wellbeing.

As a practice, we know that being sustainable and saving CO2 emissions is about spending as little as possible in order to save as much as possible. As a result, we offer a different perspective to our clients and the projects we are involved in and we have certainly seen a good response. In fact, we are currently working on a selection of social housing that gives properties bigger windows and a higher floor to ceiling height. So, while the invention of the lightbulb has led to building sizes being reduced unnecessarily, the energy revolution we are experiencing will allow people to live happily in homes that still have those important echoes of the past.  May/June 2021 • BuildingProducts.co.uk

CLADDING & INSULATION

Grenfell shadow still hanging over the cladding sector

f you talk about cladding people think of Grenfell; or even the thousands of homeowners having to pay money they cannot afford to manage the buildings they are living in, where poor cladding has previously been installed. But like any sector there is innovation happening and new products coming to the fore and Building Products spoke to Paul Richards, Managing Director of Aquarian Cladding Systems and Peter Johnson, Chairman of Vivalda Group Plc to find out more.

WHAT WOULD YOU SAY ARE KEY TRENDS AFFECTING THIS SPACE RIGHT NOW? Paul Richards: "The cladding industry is still learning lessons from the Grenfell Tower fire in 2017. Combustible cladding has been blamed as the contributory factor and though there is now a better understanding of how to use combustible materials safely, the whole industry has had to have a good look at itself. "The Grenfell Tower Inquiry continues to delve into practices of all sectors of the industry engaged in its refurbishment some five years ago and Phase 2 of Module 2 put the spotlight on the testing, certification, and marketing of cladding products. It identified a catalogue of misleading, ambiguous, and misrepresentative information provided by suppliers, as well as flaws in the testing and certification process. "The industry is already addressing some of these issues before the official findings are announced in 2022. "Of course, the other issue is in how to address the scandal of properties clad in materials deemed unsafe. I responded to the Hackitt Review in 2018, stating that we should be careful of a knee-jerk reaction leading to a ban on all combustible cladding materials and a subsequent pariah-like impact on the value of the nation’s estate. "It’s nigh on impossible to retrospectively identify if a building has been built correctly, using appropriately located and installed cavity firebreaks for example. So, consultants

err cautiously and condemn buildings which may be perfectly safe. "Our portfolio consists of a combustible cladding solution and we have been asked to supply very small quantities of replacement materials where a fire has occurred. It’s not common knowledge as there was no loss of life or asset. So not all combustible materials behave like those used on Grenfell Tower." Peter Johnson: "In the wake of the Grenfell tragedy in 2017, the cladding industry has undergone huge change, which has thankfully seen the less reputable cladding suppliers making a swift exit from the sector. In the light of the Hackitt Report and more recent enquiry led by Martin Moor-Bick, we’ve seen a significant shift in the industry, which has led to specifiers and architects quite rightly becoming much more aware of the safety and fire performance of the cladding that they are choosing. "For this reason, we’ve seen a big move to A-rated cladding products such as solid aluminium, glass reinforced concrete (GRC) and fibre cement. Let’s be clear – there is still a viable place in the market – typically on low level office block and non-residential buildings – for products made of high pressure laminates (HPL), but we’ve seen demand for this cladding type reduce in the last few years. "The widespread adoption of solid, often natural materials is definitely bringing back confidence to somewhat beleaguered facades market as it emerges from the challenges of Grenfell, the recession and of course the COVID-19 pandemic. "In terms of specification, we are also seeing architects taking a much more active role in the consideration of not just boards, but fixings, frames, insulation and other elements of the complete façade system."

Cont. May/June 2021 • BuildingProducts.co.uk

FEATURE WHAT PRODUCT INNOVATION IS HAPPENING IN THE CLADDING AND INSULATION SPACE? Paul Richards: "Due to the current focus on fire performance, new products coming to market are likely to be non-combustible. There seems little point in spending time and money on product development of a combustible solution, which will likely fail to provide the desired return on investment. "It seems the focus of technical performance questions is now on combustibility, whereas previously it was weathertightness, fatigue and thermal movement. There is a danger that there is too much focus on fire.

"Of course, the effect of fire can be devastating in a single incident and safety of the occupant should always be paramount during the design and construction process. We do not have an especially bad history of building fires in the UK and there are some in the industry who stand to make commercial gain from the hyperbole, leaving many building owners and occupiers who don’t fully understand the technicalities now living in fear needlessly, with their property deemed a high risk. I am sure building warranty providers will attest that buildings fail due to rain, wind and thermal movement on a far more regular basis. "It’s therefore important that whatever the innovation, it must have the right balance of risk. Costly, overengineered solutions are as unlikely to be used as cheap, under-engineered ones." WHAT ARE THE CORE PRODUCT OPTIONS AVAILABLE AND OF INTEREST TO ARCHITECTS AND SPECIFIERS? Paul Richards: "There is a noticeable drive towards brick cladding systems, which offer a robust solution with a facade appearance acceptable to most planning authorities.

▴ Paul Richards CEO Aquarian Cladding

"Not so long ago it was a hard sell to convince an architect that they weren’t cheating with a ‘fake solution’ which compromised their professional integrity. Nowadays there is a range of uncompromising solutions which

provide the designer and client with more options than traditional brickwork, due to their design flexibility, light weight, and efficiency of construction. And repeatedly they are proving to be more cost effective. "The cladding market has definitely stepped up to the challenge to meet the newfound demand for A-rated solutions." Peter Johnson: "Prior to Grenfell, there was not a huge amount of choice for architects looking for colourful, tactile facades. That has changed dramatically with the introduction of A2 paint finished boards such as those from Rockpanel. Similar levels of safety and product choice are also available from Etex Exteriors, through their range of coloured fibre cement panels. "More specifiers are also looking at other materials such as GRC (glass reinforced concrete) and brickslip for a higher grade aesthetic. Demand for Rieder’s lightweight GRC (which we supply via our Pura Facades brand) has increased markedly in the last three years and can be seen on stand out projects such as Symphony Hall in Birmingham and The Corniche in London. We’re also seeing a lot more interest in solid aluminium cladding, which still gains a powerful A-rating with a host of quality assured colours from tried and tested names such as Akzo Nobel and DuPont. " IS THERE A DOWNSIDE TO OVERSPECIFICATION WHERE CLADDING IS CONCERNED? Peter Johnson: "Façades and cladding specification used to be seen as a low risk, non-contentious decision, even an opportunity for the unscrupulous to cut costs. That mindset has now been turned on its head, with architects and developers opting for an ‘A1 or nothing’ approach to cladding. While this elevated view of safety must be welcomed, those involved in designing building envelopes need to bear in mind there is a delicate balance that needs to be achieved between cost (of the material and installation), aesthetic (look and longevity) and performance (U-value, fire safety and weatherproofing). "In recent months, we’ve seen a perfectly understandable, and yet somewhat needless, rise in overspecification of cladding – which adds cost and time to a project without any tangible benefit to the building owner or resident.

Let’s talk about cladding Vivalda Group launches Clad Master video series Vivalda Group, the UK’s largest independent supplier of nonflammable cladding, is producing a series of videos to improve the construction industry’s understanding of issues such as cladding materials, fixing systems and fire safety specifications. With contributions from GRC specialist Pura Façades, aluminium fabricator MSP (Scotland) and Vivalda itself, the first season of four short films aims to stimulate debate among specifiers and installers alike on a range of current cladding related topics. The first Clad Master video covers the topic of achieving A-rating fire safety with coated aluminium cladding. With contribution from MSP’s general manager Gillian Thomson, this film explores the recent ‘A1 or nothing’ trend among specifiers and the surprising rise of PVDF coatings in

PROJECT IN FOCUS

NEWTON WATERPROOFING

LONDON COMMUTER TUNNEL GETS COMPLETE PROTECTION THANKS TO NEWTON WATERPROOFING

he Limehouse Link Tunnel is a busy London commuter route which recently required protection from unwanted water ingress thanks to Newton Waterproofing, the leading independent UK supplier of structural waterproofing systems.

The 1.1-mile tunnel stretches beneath East London, connecting The Highway to Canary Wharf in London Docklands, and was experiencing a water leak near the roof of the structure at the tunnel’s entrance. Main contractor RMS (A13) Plc turned to Newton Specialist Contractor, and injection resin specialists, ASF Waterproofing to repair the structural cracks and concrete joints. Following an initial investigation, ASF worked alongside Newton to provide a suitable waterproofing solution and opted to inject the TRADECC PC Leakinject Uni 6816 E polyurethane resin into the structural cracks and joints. Part of TRADECC's high performance specialist injection resin range for water sealing, soil consolidation, and structural and concrete repair, the PC Leakinject Uni 6816 E resin is exclusively available in the UK from Newton Waterproofing.

When injected, the resin reacts to form a strong, hard seal in structural cracks and joints, stemming the flow of water and returning the structure to full working order. The project was particularly challenging due to both time and access restrictions. As the water ingress was located near the roof, the entire tunnel needed to close for the repairs to be carried out, which was only possible between 11pm and 4am to minimise disruption to the roads of London. Such a short timeframe meant that, after setting up a cherry picker and scissor lift to reach the area and clearing the site by early morning, ASF were left with just a four-hour window to carry out the works each night. However, despite the restrictive time windows, ASF completed the project in a timely manner, with both the tunnel and the vehicles that use it now protected from unwanted water. Shaun King, Director of ASF Waterproofing, commented: "Despite the challenges presented to us with this project, ASF managed to successfully waterproof the Limehouse Link Tunnel using the specialist injection resin, Newton 320-FP. This resin was ideal for this project due to its ability to react quickly with water to effectively seal the cracks in the concrete." The project is a perfect demonstration of the quality of Newton’s network of Specialist Contractors and their exclusive UK distribution partnership with Belgian construction chemicals specialist TRADECC. Newton Waterproofing’s MD Warren Muschialli said: “The Limehouse Link Tunnel project not only shows ASF Waterproofing’s outstanding quality when it comes to injection resins and structural repair work, it also shows how adaptable they are, with the restrictions not compromising the quality of the work carried out. “It also demonstrates the value of our partnership with TRADECC. Customers and partners of Newton Waterproofing can now profit from TRADECC’s 50 years’ experience in the manufacturing of products for waterproofing, water sealing, soil stabilisation, concrete repair and structural reinforcement.”  About Newton Waterproofing Waterproofing experts for over 170 years, Newton provide the best waterproofing and damp proofing systems for all structures, from new and existing domestic properties to large-scale commercial developments.

Air leakage. it doesn’t matter how low your U-values are if there are draughts

addy Leighton of Huntsman Building Solutions-Icynene, Spray applied insulation, explains why minimising air leakage must go hand-in-hand with better insulation.

Better insulation of domestic households is seen as one of the most important ways of reducing carbon emissions and slowing the effects of climate change. A recent environmental audit select committee report says that 19 million UK homes are poorly insulated that unless urgent action is taken to improve energy efficiency of homes, the UK will fail to meet its climate targets. Unfortunately, as over 60% of our current housing stock built pre-1960 when little thought was given to heat-loss prevention, the challenge is significant. Overall, roughly 20% of UK carbon emissions are generated through 36

BuildingProducts.co.uk • May/June 2021

heating, hot water and cooking in domestic properties. Even more troubling was the fact that in 2017, emissions from buildings actually rose by 1% over those of the previous year. Basic principles If we go back to basic principles; heat loss in a building occurs through a combination of four processes: conduction, convection, radiation and mass transfer. The colder the outside temperature, the warmer the inside, and the worse the thermal insulation of the building envelope, the greater the heat loss will be. In the UK, the construction industry focusses primarily on U-values - sometimes referred to as heat transfer coefficients- as a measure of conductive heat loss. These are used to measure how effective elements of a building's fabric are at insulating against heat loss. The lower the U-value of an element of a building's fabric, the more slowly heat is able to

transmit through it, and so the better it performs as an insulator. Very broadly, the lower the U-value, the less energy is required to maintain comfortable conditions inside the building. Unfortunately, measuring the thermal efficiency of a structure by U-value alone fails to consider heat loss through air leakage. If you spend any time in high mountain environments you quickly realise that it is the wind that strips the heat from your body, and it is the same in buildings. It doesn’t matter what your U-value is if there are draughts. Traditional forms of insulation are relatively inefficient in preventing air leakage through draughts. They can’t completely fill the complex voids in roof structures or seal the interface between the insulation and the building components. They can also struggle to cope with small structural movements which can lead to air gaps.

INSULATION

When 40% of a building’s heat loss is caused by air leakage, an insulation system that works to prevent air leakage – effectively creating a “sealed box” environment, is essential to minimise heat loss.

Spray applied, open cell insulation Breathable, open cell spray applied foams are highly efficient insulators against both conductive and convective heat loss as they control air movement and eliminate air leakage. Spray applied foam insulation is also extremely flexible; it moves with the structure, maintaining its insulative properties for the lifespan of the building. Spray applied foam insulations such as HBS-Icynene Foam Lite are open cell materials which have a soft, yielding texture. This not only provides outstanding insulation properties, but also allows the building to breath naturally, resisting internal condensation – particularly important when insulating heritagetype buildings. Control of air quality Heat loss through mass transfer is more complex and relates to how much moisture is held in the air (humidity). The more there is, the more energy it takes to heat it, so to feel warm, damp buildings need more energy than dryer ones. To control humidity, you need to be able to control the air movement and you can only do this if the

building is relatively airtight. Spray foam insulation does this effectively and quickly by sealing air gaps, enabling controlled ventilation and mechanical heat recovery systems to perform efficiently. A holistic approach to heat loss mitigation High performance insulation, effective control of air movement and air quality, in combination with low carbon heating are interconnected elements that need to be addressed as-one in the design of newbuild housing to ensure heat loss mitigation. Until Building Regulations take a holistic view of this complex picture, the industry will continue to build housing that perform well in one respect but fail in others From a wider perspective, bringing the UK’s legacy of pre-1960’s, poorly insulated housing stock up to a sufficiently high performance is a whole different ball-game, one that needs urgent attention at the highest level.

OPINION

When it comes to heating and ventilation, focus on the environmental cost

ar-sighted investment in quality ventilation systems is the only lasting way to tackle mould in social housing, argue Nick Gander and Rod Davies of Energy Carbon.

We’re willing to bet that very few people spend their evenings thinking about the state of heating and ventilation in Britain’s social housing. As a topic, it’s extremely niche - one where discussion is limited to a few thousand professionals, experts and politicians. Or at least that’s normally the case. Earlier this year, however, it was suddenly thrust into the mainstream when ITV uncovered the appalling condition of social housing in South Norwood, Croydon. Millions of people saw shocking images of walls and ceilings totally caked in black mould, and flats so damp that some tenants had been forced to unplug all electrical appliances. Residents explained how they’d made repeated complaints to Croydon Council, but received little or no help in return. At least one family was found to be living out of a single room – the only one on the property that was fit to live in. Not fit for human habitation In the days that followed, experts condemned what they’d seen. Dame Judith Hackitt, formerly Chair of the UK Health and Safety Executive, said "There isn’t really any possible way those properties are fit for human habitation." 38

BuildingProducts.co.uk • May/June 2021

She and Polly Neate, Chief Executive of housing charity Shelter, agreed: "These were the worst living conditions they’d ever come across in the UK." And there’s no question – the fact that anyone in Britain is living in accommodation like that is appalling, let alone social housing tenants. But given the attitude Governments and councils have taken to social housing in recent decades, it’s not especially surprising. In fact, it’s arguably the natural endpoint of an extremely short-term, short-sighted approach to heating, ventilation and social housing in general. The consequences of short-term thinking In this situation, it would be very easy to lay all the blame at the feet of Croydon Council. But according to the Institute of Fiscal Studies, council funding from central Government has been cut by 26% since 2010. In November last year, in fact, Croydon Council went bankrupt.

"A HIGH-TECH MODERN VENTILATION SYSTEM, LIKE OUR OWN AIRUNIT PRODUCT, CAN REPLACE STALE AIR FROM INSIDE A HOME TO FRESH AIR FROM OUTSIDE IT – ALL WHILE RETAINING UP TO 98% OF THE HEAT." Nick Gander

Local Governments have always had to watch the pennies. But over the last decade, those budget reductions have inevitably led to even more cornercutting and short-term thinking. Let’s take heating and ventilation – our own area of expertise – as an example. If, like many councils across the country, you’re very strapped for cash, but have housing stock with a mould problem, the most affordable response is to do nothing much at all. Maybe put in some dehumidifiers, or encourage residents to leave the windows open. But as we see in Croydon, those sorts of piecemeal measures don’t

work – they just delay a problem that, eventually, can make the properties you manage virtually unliveable. A more lasting solution – that’s more expensive at first but will prove much more cost-effective over time – is to invest in proper ventilation. A high-tech modern ventilation system, like our own AirUnit product, can replace stale air from inside a home to fresh air from outside it – all while retaining up to 98% of the heat. A heating revolution Both to prevent mould, and to reduce

the huge carbon footprint of home heating, we believe there needs to be a fundamental shift in how we heat properties, too. Mainstream convection heating works by heating the air – and when that warm air comes into contact with colder surfaces, like windows, it forms moisture. But infra-red heating, another Energy Carbon speciality, is different – it warms surfaces rather than the air. That means the air doesn’t get as hot, and there aren’t any cold surfaces on which condensation can form.

In our view, heat recovery air ventilation combined with infra-red heating provides the best way of beating mould – and making the built environment more sustainable, too. Better homes, greener planet Ultimately, when it comes to heating and ventilation, we believe that we need to focus on the long-term cost (financially and environmentally), not just the upfront cost – and that Government has to give councils the funding they need to make the most sensible long-term decisions.  May/June 2021 • BuildingProducts.co.uk

THE IDEAL WINDOW FOR THE MODULAR MARKET

n the face of it, Euramax’s 70mm uPVC window is not so different to any other. But as Nick Cowley, the company’s Managing Director explains, dig a little deeper and the reasons why it’s ideal for the modular market are obvious.

For uPVC window, door, and composite door manufacturer Euramax, moving into the modular sector was the next logical step. From making its name in the holiday home and leisure market before expanding into the construction sector, the 70-year-old company is now gaining a reputation as the UK’s leading manufacturer of fenestration products to modular and offsite thanks to its 70mm Eurocell Eurologik window. Which, on the surface, might seem like an idle boast. After all, according to Insight Data, the leading provider of marketing data in the UK fenestration and construction industries, around 1,200 fabricators are currently making uPVC windows.

“Just because you can fabricate a 70mm window system, it doesn’t mean that you have the logistics in place to deliver it in the way a modular construction firm wants,” says Nick Cowley, Euramax’s MD. “Our window performs perfectly on the technical side of things, by providing great energy efficiency and being made to measure, but what really sets us apart is our service levels and delivery systems.” As a result, Euramax is already working with some of the biggest names in the sector and, having been acquired by Modular Group Investments earlier this year, the company is set to become a big player in modular construction.

fix brackets to allow an entire holiday home to be installed in the time constraints. It’s this approach to lean manufacturing, influenced by highly efficient practices in the automotive sector, which has allowed Euramax to hit the ground running. “Companies may be offering a similar product, but it’s the service level and the manufacturing processes we’ve put in place over the last 70 years that set us apart,” says Nick. “That’s what has allowed us to help customers meet the challenges they continually face in the modular sector.”

A streamlined process Euramax’s history in the holiday home market has provided the company with both the tools and the expertise to move into modular.

“Our focus has always been on developing those systems to enable us to deliver better quality products, faster lead times, and an overall better customer experience.”

To cope with a production process that was making several holiday homes every hour on multiple production lines, Euramax manufactured windows and supplied them pre-glazed with quick

Once the windows have been manufactured at its 205,000 sq. ft. factory in Barnsley, they are delivered in dedicated stillages across the country. Meeting a demand Lots of companies will deliver products in bulk, split across multiple boxes. When it comes to installation, that means all the components may not be there, or some may be broken or damaged, creating hold ups that modular companies can ill afford. Euramax’s lineside delivery system means that everything is packaged together and in one place, making for an easy install. “By its very nature, modular construction requires precision, and smooth, well-rehearsed processes. Interruptions have to be avoided at all costs,” Nick explains. “As a result, modular construction firms are demanding when it comes to service. “They need products in a certain stillage, there has to be a certain number on the stillage, and the fixing

kit has to be packaged with all the individual components that marry to that window installation, so the two never get separated. “It takes a great deal of effort to package things reliably and accurately and deliver them in a uniform way – which is something not all window companies can do. “We see our role as a vital part of the modular process for our customers; from our production line to our delivery, we make the flow process smooth so when the time comes our windows can just be picked up and easily installed into modular buildings. “We know how important it is to keep their production lines as simple as possible.”

An easy fix Another thing that differentiates Euramax from many other window companies is the fixtures and fittings which enable their windows to be installed in modular buildings. Euramax’s fixing systems have been developed in house by the company’s R&D team. Nick says: “This combination of an innovative fixing system, quality window systems and quick, efficient installation methods is a very attractive package for the modular sector. “It’s what sets a Euramax window apart from a standard trade window – and what sets us apart from any other window producer.” 

JULIET BALCONIES: A SIMPLE SOLUTION FOR ACHIEVING LUXURY

y allowing homeowners to let more air and natural light into their living spaces without compromising on safety, Juliet balconies have many advantages. Here, F.H. Brundle’s Head of Marketing Paul Smith talks about the extensive range the company has to offer.

Juliet balconies, also known as ‘balconettes’ or ‘French balconies’, get their name from the famous balcony scene in Shakespeare’s Romeo and Juliet. Simply put, a Juliet balcony consists of a balustrade fixed to the external façade of a building to allow rooms on the first or higher floors to have inward-opening, full-height French doors, which means more light, a greater sense of space, more views, and more air – a simple solution to achieving the luxury feel of a balcony with relative simplicity. Juliet balconies are a great way to enjoy the many advantages of a

balcony, but without the structural complications. Vast range One company that installers can rely on to meet all their Juliet balcony requirements is F.H. Brundle, a leading supplier of handrails and balustrades in a wide range of materials and finishes. The company offers several glass Juliet Balcony systems. The first is the Sky Force Balcony, the first practically invisible system on the market. Cost-effective and simple to install thanks to its ‘slide & click’ design, it can be mounted directly onto the window frame or masonry. This system is aluminium anodised, covers widths of up to 3000mm with only one two-part balcony kit, and is suitable for 10 to 21.5mm glass. Next is the Elegance Juliet Balcony, where the glass sits 80mm off the wall, reducing its visual impact. Designed to suit a 40 x 30mm rectangular top rail system and 12 to

21.5mm glass, this system comes in a satin polish finish, and requires no welding. F.H. Brundle’s Elegance Romeo Balcony shares the same features as the Elegance Juliet Balcony, but is designed to suit a 60 x 30mm oval top rail system. A third option is the Verona Juliet Balcony, which comes as either a kit with glass clamps on the top and bottom rail, or as a kit with a split tube on the top rail and glass clamps on the bottom rail, both with an opening width of 2300mm and an overall width of 2650mm. For these glass systems, F.H. Brundle supplies a range of stocked glass panels – choose from either toughened monolithic clear float glass or PVB toughened laminated glass. Their custom sized glass panels are polished on all edges and come with docked corners for safety and aesthetic reasons. The glass can be supplied with a radius corner, shaped, with cut-outs and drilled, while a range of coloured glass, etched glass, and self-clean coatings are also available. Lastly, F.H. Brundle offers the Fortitude Traditional Juliet Balcony made from zinc plated steel with a black PPC finish and comes in three sizes to meet the needs of single and double door widths. F.H. Brundle’s Head of Marketing Paul Smith comments: “Juliet balconies enhance the way a home looks from the outside without the structural complications of a traditional balcony, and allow homeowners to let in a large amount of natural light without having to compromise on safety. “At F.H. Brundle, we’re keen to help our customers offer this appealing home improvement product and give them the edge over their competitors – our aim, as always, is to supply our customers with top quality products and first-class service.”  May/June 2021 • BuildingProducts.co.uk

FLOW REGULATORS

THE TOUCH-FREE DRINKING WATER RANGE FROM ZIP WATER

Flow regulators are devices that control the flow of water through our household appliances. They are manufacture here in the UK by Neoperl and are made in hundreds of sizes that can now be retro fitted to taps and showers throughout the home. No excuses, everyone can now do their bit to save water and the energy that heats it. Most taps will already include a flow control device at the end of the spout and it’s often only when in situ that one can identify whether the flow is too strong. We’ve all experienced a splashing cloakroom tap for instance where the flow is too fast for a smaller basin. Now the incumbent device can be easily removed and replaced with one that reduces the flow to a comfortable level. The same with showers, a valve shower often delivers far too much water and even a slight reduction adds up to a substantial water saving over the year. Regardless of the prevalent water pressure, a flow regulator maintains a consistent water stream at the chosen flow rate. A typical flow regulator consists of three components, a housing, a seating area and a precision-ring. The flow is determined by the interaction between the seating area and the o-ring. As water flows through the device at a higher or lower pressure, the shape of the o-ring changes to restrict or release the flow of water. Now is the time to look at our own homes and advise our clients on this easy water saving win. As our clients spend more time working from home and adding home improvements in abundance, why not take the opportunity to talk with them about saving water too? Especially as we are all spending so much more time washing our hands resulting in many thousands more litres of water being washed down the plug hole.

It can withstand deliberate attempts of forced entry using category C tools including an axe, hacksaw, drill, bolt cutters, and a wood chisel. Additionally, for higher risk premises it can be certified to F1 and G1, providing resistance to professional attempts at forced entry.

Rinato – the robust, stylish timber-alternative for decking

F.H. Brundle’s composite decking boards offer a robust, sustainable and easy-maintenance alternative to timber. Made from 60% recycled wood, 40% plastic, they look like wood but without the hassle, with an authentic colour and texture that mimics the look of timber.

Constructed from a double layer of 34mm kiln-dried and pressure treated timber boards, and hot-dipped galvanised steel posts, it is guaranteed for 25 years. The flat profile provides a secure anti-climb barrier with no hand or foot holds, and it can be topped with security spikes or alarm systems for increased protection.

They’re also splinter-free, UV resistant and anti-slip, with a workability similar to wood.

The interlocking timber boards with a deep V tongue and groove joint minimise gaps that sound could travel through, providing noise reduction of up to 28dB, making it ideal for data centres and other sites need to reduce their noise impact on surrounding areas. Jakoustic® Class 3 has a natural appearance not far from a more robust garden fence, which is welcome in many settings. Its solid design also provides privacy and concealment.

Victoria M board incorporates less composite material, making it lighter and more economical, and especially suited to gardens, patios or balconies.

It also offers fast installation times; built on steel I beam posts, the timber boards simply interlock to create the desired height, and have been tested to heights of 3250mm.

Virtually maintenance free

Rinato decking boards come in four different options. Natural features a 360-degree wraparound polymer Capstock shield, offering year-round protection against the elements.

Our robust classic solid boards are an excellent choice for areas with high footfall, making them a natural fit for both residential and commercial applications. FEATURES

Excellent UV resistance Easy to install Anti-slip resistance tested Made from recycled material

Jakoustic® Class 3 is far from an average security fence, but its combination of features offers great potential to many sites. Contact Jacksons Fencing today on 0800 408 4759. 46

Driving security forward with the complete package

f you were selecting a car for security reasons, would you be looking for one that just had four wheels, an engine, and a door you could lock? No, of course not! You would rightly be interested in its overall performance, verified roadworthy tests, the quality of its components, not to mention other safety features and naturally its appearance and stylish kerb appeal.

Selecting the right Secured By Design (SBD) Doorkit is not dissimilar. It’s not simply a case of meeting the minimum requirement, with a piece of paper that says SBD Tested, anything will do! After all there is so much more to consider in the modern build environment, from fire rating to life cycle expectations and installation to design flexibility. Portaro SBD Interior timber Entrance Doorkits from Vicaima provides just that scope, with ease of assembly, quality materials, outstanding performance, and design appeal as standard, all encased in one of the most comprehensively certificated products on the market. Of course, one of the first considerations for any project or development is how will it look and will it fit in with the project design theme. Here the Portaro SBD system provides a rarity in today’s somewhat limited market. With matching door, frame, and architrave in a myriad of veneered, foil, laminate, paint lacquered and even special finishes, the Portaro system offers complete design freedom, so that performance does not equate to compromising aesthetics. Beyond the finish itself, design configuration also offers flexibility, with a choice of either a conventional architrave or for a seamless face the Inverse system, where door sits flush with its surroundings. All door systems incorporate a three-Point locking system, handle, and security escutcheon, together with an automatic dropseal.

Returning to our choice of car for a moment, another prerequisite in any purchasing decision, would be to lift the bonnet for a peak at the engine. Obviously a little harder to do with doorkits, however it should be remembered that the important performance of any security door assembly is often not visible to the naked eye. Here again no ‘cutting corners’ or ‘good enough’ criteria are employed when manufacturing a Portaro SBD Doorkit. The doors themselves are constructed with heavy duty and high-density cores, surrounded by double timber rails on all sides, complete with hardwood lippings. Furthermore, the frames are made from hardwood and come pre-fitted with fire, smoke, and acoustic seals. From the installers perspective, the Portaro SBD System really is the complete package. Supplied as doorkits for ease of fitting on site, the carefully and separately wrapped doors come pre-machined with all primary components, alongside the boxed and matching frame/ architrave sections with simply connecting parts and screws. All designed for easy and rapid assembly.

There are so many reasons why Portaro SBD Doorkits offer the ideal entrance security solution, of which these are just a few: •

Certified Secured by Design with dual scope Fire and Security certification

•

Sound reduction performance with Acoustic AC35 and AC36 options

•

Completely matching door and frame surround

•

Ease and speed of assembly on site

•

Quality components and construction

•

FD30 to FD60 Fire Rating

•

SBD Inverse Model

For anyone looking to move out of first gear when it comes to security standards, then Portaro SBD Doorkits really are worth a test drive.

HYGIENE, ENERGY EFFICIENCY AND SAFETY DRIVING THE COMMERCIAL DOOR SECTOR

uilding Products looks at some of the trends driving the commercial door sector and asks – what products should architects, and specifiers, be looking at?

Security, energy efficiency and aesthetics have long been three of the most important factors when looking for a commercial door – alongside price of course. But the pandemic and the last year has also put a huge focus on hygiene and commercial doors that kill bacteria and reduce the risk of infection. Ken Price, who is Managing Director of ADSA - the Automatic Door Suppliers Association, tells us more. He says: “Our industry has been incredibly resilient and responsive throughout the pandemic. Now that

the situation is beginning to improve, the demand for ‘no touch’ and ‘clean touch’ solutions to allow society to operate with more normality while at the same time ensuring their safety, is increasing. “Initially, demand emanated from hospitals, care homes and key worker environments along with essential retail. But as the UK reopens for business, there is sure to be demand from other sectors, especially those involved in sports, leisure, recreation, and other public buildings where there is a need to maintain cleanliness, minimise contact and manage volume and foot traffic more efficiently around buildings.” In regard to what product innovation is happening in the Commercial Door space, Ken explains further.

He says: “Many of these solutions have used innovative materials, such as anti-bac surfaces, or new technologies to develop and deliver solutions. Others have used existing products which have been adapted or extended to produce a solution to address immediate problems. “Even before COVID-19, there was a growing interest in smart buildings and integrated solutions. However, applying these across large estates or retrofit to an existing building was sometimes seen as a bit of a luxury. Creating smart buildings does require investment but the efficiencies they provide are not only cost effective but are easier to manage and maintain long-term. “Realistically though, not all owner/ occupiers of commercial buildings have been able to afford to make their premises smart. What the pandemic has forced upon us, is the need to do thing differently and this has included using technology to apply solutions to specific problems and this is entering the door space.”

"EVEN BEFORE COVID-19, THERE WAS A GROWING INTEREST IN SMART BUILDINGS AND INTEGRATED SOLUTIONS. HOWEVER, APPLYING THESE ACROSS LARGE ESTATES OR RETROFIT TO AN EXISTING BUILDING WAS SOMETIMES SEEN AS A BIT OF A LUXURY. " Ken Price

Jeremy Phillips is Chairman at the CDW Systems Group, which is a business that manufacture and supply a range of commercial doors. On the trends he is seeing, he says: “Thermal efficiency is very much coming to the fore and we expect to see an increasing shift in thermally broken commercial doors rather than non-thermal ones. Although there is still good demand for the old fashioned non-thermal systems, that will perhaps start to wane a little in favour of products with good thermal efficiency. “We will also see more demand for acoustically efficient product as well as acoustic performance is being built into the spec more and more now. “There is more complexity in the different types of hardware that are asked for on commercial doors now too, such as different forms of security for fire escapes, and different entry systems. “This will make the whole manufacturing process much more complex, which is fine because that’s what we do, and we are currently manufacturing doors for various projects that are going to be fitted and then automated in various ways. “Shorter lead times are also now becoming the norm on commercial doors, and at CDW Systems we have invested in new machinery and production capacity so that we can offer lead times of three weeks on standard finishes.” When it comes to what are the core product options available and of interest to architects and specifiers, Ken says that with commercial doors being evaluated now is good to time offer new and innovation solutions. He says: “Because many of these adaptations have been made in isolation, we are now seeing many owners and managers of large estate looking to audit and revaluate the solutions that they have in place to optimise them for greater integration which will allow them to oversee diagnostics, maintenance and management of systems.

These have been ▴ Jeremy Phillips Chairman particularly CDW Systems Group prevalent within medical environments, such as laboratories, which are used for testing or the control of biohazards. “But again, the roll-out of these technologies will encourage their extended use which will provide convenience to the end user and an overview for facilities managers through the digital tracking and reporting mechanisms which accompany them.” Jeremy agrees that security is a major driver, when talking about what is interesting architect and specifiers. He explains: “There is more of a range of levels of security available for architects now, and DDA compliance is becoming almost essential in a lot of projects now and that is something our commercial doors can satisfy very well, including the actual width of the doors and the strength of the closers. “The strength of the closers is something that can be missed on commercial doors; having too strong a closer will not satisfy DDA, so that is certainly something that is being specified more specifically now. “There is also now a much better understanding of what is available out there and it does rely on architects knowing what the options are. “When projects are starting, we always encourage architects to get in touch as soon as possible because what often happens on projects is that we will get presented with a spec and it’s either not what it should be or may not even actually be possible. “So, if we’re involved a bit earlier, we can just make everyone aware of what is possible and make suggestions of what might be a good idea to satisfy the requirements of the projects.” 52

CASE STUDY

CDW SYSTEMS HELPS CLEARWAY DOORS & WINDOWS UPGRADE GOLF HOTEL AND SPA LOBBY CDW Systems helped Clearway Doors & Windows complete a successful installation at a golf hotel in Oxfordshire. Clearway Doors & Windows was tasked with replacing the hotel lobby doors at The Oxfordshire Golf Hotel and Spa and the team called on the expertise of sister company CDW Systems, who supplied the new frames from Technal’s 202 commercial system. Designed for commercial projects just like this, Clearway Doors & Windows installed two screens, each comprising a set of double automatic sliding doors. Fitted with ABS Ultimate cylinders, high security escutcheons and laminated double-glazed units, the doors provide the hotel with a functioning, secure and comfortable environment. The 202 Commercial Door is a non-thermally broken aluminium framing system which can incorporate single or double doors and automated sliding doors having been designed for entrance screens and shopfronts. Richard Smith, Technical Director at CDW Systems adds: “Technal’s 202 commercial system ticked all the boxes for the hotel lobby, and we take great pride in the fact that we can offer the right solution for any project, using our extensive aluminium range.”

Not all riser doors are fire tested equally. Ensure legal compliance with bi-directional testing Our renowned 4000 Series riser doors have always been specified by architects for delivering the highest standards in third party fire certification without compromising on architectural design. Unlike the rest of the industry, we fire test our riser doors from both sides to ensure legal compliance and still achieve 240 minutes certified fire rated performance. Given the choice, why would you specify anything less?

BuildingProducts.co.uk • May/June 2021

Commercial spaces have had to adapt to new challenges presented by COVID-19 over the last year, and consequently, specification requirements for access systems have also shifted. INFECTION CONTROL Reducing the spread of bacteria

and viruses has become increasingly important across every sector and minimising the number of common contact points at entrances and exits is a key step in bacteria control. This has generated greater demand for touchless door automation, with products such as a dormakaba touchless activation switch that utilise infrared technology, replacing traditional manual touch pads. A successful example has been the implementation of Safe Entry Flow in the essential retail market. Acting as an automatic door operator to control the flow of people into a store,

end-user experience. This innovative solution has been installed by dormakaba to help essential retail stores to comply with social distancing requirements, as outlined in the Government’s operating guidelines. ENERGY EFFICIENCY Energy-saving products for buildings are the trend of the future. With the ST FLEX Green sliding door, dormakaba underlines their contribution to increase energy efficiency and thus to improve the sustainability of buildings. In addition, energy efficiency of the doors themselves is being more widely considered such as dormakaba KTV revolving doors which now delivers energy savings of over 60% in operation and over 90% when on standby compared with a traditional revolving door. Tested to EN 16005 and tested and certified up to two million cycles, it allows an efficient and safe flow of people while saving energy with low consumption in use and reduction in temperature exchange and unwanted noise or dust.

Safe Entry Flow is a people counting system that uses 3D and Thermal Imagining to capture footfall data within a store. The counting system links to an automatic door operator, only allowing entry when the number of customers in the store is within a pre-set range (depending on the size of the retail unit), therefore creating a physical barrier to prevent overcrowding. A traffic light system and sound box are also linked to the system to provide visible and audible signals to customers at the store entrance, providing a simple and enhanced

MEETING COMPLIANCE Of course, meeting building legislation surrounding commercial spaces is also crucial, including compliance with the equalities act and with fire regulations. Approved Document B should always be consulted to ensure all areas of compliance are met; and this outlines that all fire door hardware must be CE Marked, have a Declaration of Performance (DoP) from the manufacturer, and that it must have been tested by a thirdparty scheme. All three of these must be present when specifying – if even one is missing, this invalidates other components, and the product should not be considered for installation.

As such, independent UKAS accredited fire certification schemes such as the Certifire scheme are increasingly being recognised as essential for automatic door operators, as it guarantees performance, quality and reliability of the product, as well as traceability. The risk of theft is also prevalent within commercial environments, and products that are proven to protect both staff and valuable items are far more likely to be specified to provide the utmost reassurance. Suppliers such as dormakaba have seen an increase in consideration for products that meet RC2 and PAS-24 attack standards, such as PAS-24 Compliant Sliding Doors, and recent upgrades to the dormakaba KTV Automatic Doors, that now include a RC2 certified Night Shield. Compliance with the Equalities Act must also be considered, and automatic doors are now more widely adopted throughout buildings to ensure employees and customers of all physical abilities are able to use the building successfully without compromising security. Such adoption goes beyond the minimum requirements of the Equalities Act and is seen as being increasingly important in order to improve the user experience, attract and retain staff, and encourage repeat customer usage. Commercial spaces are updating to meet new challenges, and this includes more careful consideration for entrance and exit systems. By working with suppliers such as dormakaba, owners of commercial premises are guaranteed unbeatable support from one trusted source; from site-visits and drawings, through to remote software updates and dedicated aftercare where possible. 

CREATING

THE UNTHINKABLE by John Osborne

ffice managers, designers of workspaces, architects, and developers have been forced to think the unthinkable during the pandemic – how to maintain a safe working environment that complies with constantly changing Government rules while preventing costs from going sky high. John Osborne talked to some experts and explains why so many are now considering the enormous issue of the very nature of office work.

BuildingProducts.co.uk • May/June 2021

It is an incredible challenge. Some buildings can be quickly put up. In a war field, hospitals can be quickly erected using tents. Field hospitals are workspaces, but then at the other end of the spectrum parliament buildings and prisons are also workspaces. However, it is impossible to change the fabric of those buildings in the timescales dictated by pandemics.

The pandemic has forced many experts to consider the unthinkable. That is how to maintain a motivated workforce with so many conflicting pressures. Developers like change because the more often a site is redeveloped the more opportunities there are to make money. However, office moves have to be planned to prevent a business losing revenue and some staff

leaving because they cannot cope with a new office.

Factories are also work environments but often humans work in them on production lines working closely with machines. An office is a much more varied environment. It usually has to be accessible to customers, but it also has to provide a space in which creative people such as architects, advertising copywriters; and lawyers can find creative solutions to often complicated and complex problems. The eureka moment may come in a corridor while waiting for a machine to dispense coffee or tea or it could come in a boardroom. Also, while many people have been talking about hybrid workspaces in which people work at home and connect with colleagues; directors; clients; customers; and suppliers using Zoom and go, less often than

they used to into an office the reality is that the hybrid model is new. It may not work for some businesses. Chief Executives and Office Managers are facing a colossal challenge. It means that suppliers of building materials and contractors are having to radically rethink how they work, what they supply, and perhaps more importantly when they will be allowed in to actually create more versatile offices. Jitesh Patel, Chief Executive Officer of Peldon Rose, a workspace design specialist said in the introduction to The Office of the Future, a report published in October 2020: “The future of the office is dead. This is the message we’re constantly fed when switching on the news or scrolling through social media, and it’s unsurprising, given the continually changing restrictions the COVID-19 pandemic is bringing to our lives. "However, although the future may be uncertain, it’s clear that the office still has a significant role to play long-term in the working world. To delve deeper into what the future of the office may look like, we teamed up with workplace strategy and employee engagement specialists, WKspace, to commission a report into current workplace trends. "The COVID-19 pandemic and subsequent lockdowns have changed our working ways for the foreseeable future, but in many ways, this makes the role of the physical

workplace more important than ever. The office does more than just facilitate work. "It brings people together and encourages collaboration which helps to foster a positive culture, teamwork, and learning. It’s a place where talent is nurtured, development happens and where friendships are made. Although the pandemic has proved that we have a hardworking and dynamic workforce, almost half (48%) of business leaders admit that employee motivation has proved the biggest challenge in lockdown.” Mr Patel said that the office is “The creative and emotional backbone of a business which cannot be replicated virtually. With many offices still lying empty, it also means our once thriving city centres have temporarily become ghost towns. When returning to the office, it’s crucial for businesses to create safe and reassuring spaces so teams feel happy and comfortable to return to the workplace, meaning life can resume to what was previously seen as normal, all while keeping hold of the benefits we have stumbled across during the work from home revolution.

Aitken Turnbull was selected from the UK Government framework to design its flagship hub for Scotland which now sits in Edinburgh and where the cabinet will sit on any meetings north of the border. Alasdair Rankin, Managing Director, Aitken Turnbull Architects said: “The realisation that a return to offices, while welcome for many, will also present challenges and in some cases heightened anxiety. Most people who are normally office based have established new patterns for working based on their home environment and circumstances. Varied working hours; more frequent breaks; working outdoors where possible; and listening to music have all been adopted to assist people in transitioning to home working.” He believes that “the return to offices will have to address these changes, as well as the increased reliance on technology and video conferencing. Workspaces will have to address the need for multiple people to be

"The requirement to ensure that surfaces are clean and sanitised has the potential to further accelerate the contactless environment and the use of apps to configure and manage workspace. This is something that has been happening at a low level for a number of years, but the ability to call a lift; book a meeting room; unlock doors; control your lighting levels as well as ordering lunch is likely to continue to increase as we move forward in the return to offices.” Cleanliness and cleaning regimes are now high on the office agenda, as John Williams pointed out. He founded SpaceInvader, an interior design consultancy. Mr Williams said that “Products with an antibacterial element are big news in office design, ranging from fabrics to finishes, and are set to become more of a standard as the immediate threat of coronavirus recedes, but the lessons don’t.” He added: “Other products on the rise in popularity right now are prefabricated phone booths or ‘Zoom rooms’ that are easy to install or move around, whilst innovations in acoustic products are also very important, given the uplift in collaborative spaces, so that they don’t impinge on quieter working areas.

"We’ll also see more LED lights that automatically adjust to emulate daylight levels. Light has a great wellbeing role to play, as well as announcing function and adding dynamism, ensuring the workplace gives people a sense of experience they wouldn’t have at home” Mr Williams believes that the office “will definitely survive! We may well have got through this period by interacting via Zoom or Microsoft Teams – and there are certainly those who report increased efficiency because everyone is present and focused – but the subtle advantages of face-to-face meetings cannot be underestimated. People need to be together to innovate and collaborate. Culture arises out of this and represents the competitive advantage businesses need. "Younger team members also need to be around mentors to learn by observation, whilst integrating a new staff member is almost unthinkable via a screen. The mass homeworking heralded by COVID-19 has shown it can be done and proved a lot of sceptics wrong. However, whilst for many older workers or more introverted personality types it’s been a positive, for a lot of younger people it’s been a mostly negative experience. "Home-working can mean a lack of boundaries, for example, with more anxious workers glued to their screens 12 hours a day. A strong element of flexibility in terms of hours and location of work will certainly survive into the new post-pandemic era workplace, meaning occupation densities are likely to change, with fewer workstations and more spaces that allow teams to work collaboratively.

FEATURE "The look and feel of the work environment will become as experientially designed and considered as a hospitality space to provide reasons for people not to work at home. There will also be a new need to create feelings of safety via the provision of physical comfort and the minimising of stress.“ Mr Williams continued:“Real estate operators are talking to us about how to make less space more special, so whilst businesses may rent smaller premises, there’s a desire to increase their quality to attract the best staff. In some senses, the changes office managers and business owners will need to implement are nothing new - agile workplaces have been ‘the new normal’ for quite some time. What will have to change is increased listening to individual. The future is ground-up rather than top-down. It’s all about empowerment – and reaching solutions both individuals and business owners are happy with. In the longer-term, the workspace will become a hang-out for people to come together for the more collaborative parts of their work, before dispersing either into smaller pockets of space or else returning to their homes to carry out specific tasks.” However, Petr Mitev, Head of AEC Technology at Enscape believes that it will take some time for changes in offices to take effect. Enscape software enables users to create high-quality 3D real-time visualisations based on existing planning data. “With many employees still working from home”, said Mr Mitev: “It will take time before the changes to these spaces play out fully. Today, the focus is around office furnishings and layout. Open plan offices have been growing in popularity for years. These days, to help prevent viruses spreading there is a shift towards closed plan layouts.

"We are also seeing a greater focus on ventilation. Such alterations can be expensive to implement. So, for some businesses, modifications may be limited to fixtures and fittings that can be swapped in and out more flexibly rather than the implementation of a completely new heating, ventilation, and air conditioning system, for example.” Sustainability is another main concern now according to Dan Roberts, office expert and head of workspace at international, independent real estate consultancy Hollis.“We have seen a real shift towards the use of sustainable products.

Roof Tiles fit for Future Homes Standard

s the Government’s Future Homes Standard continues to encourage construction professionals to adopt a more sustainable approach to the building materials they specify and the methods they utilise, Chris Piper, Sales Director for Housing Developers at Ibstock PLC, which includes the market leading Forticrete brand, shares his thoughts on the role concrete roof tiles play in supporting a more ecological, yet efficient, approach to construction.

Aiming to achieve an uplift in the thermal performance and overall sustainability of new build properties, the Future Homes Standard highlights the responsibility and opportunities that industry professionals have to create a new generation of residential dwellings that deliver the highest standards in energy efficiency. When specifying sustainable building materials for residential dwellings, professionals must first consider the environmental credentials of the products themselves. However, the proficiency of the installation method and ongoing maintenance requirements must also be addressed, to ensure the long term performance of the property. With regard to roofing products in particular, specifiers should choose roof tiles that have a reduced impact on

the environment through their material composition. This can be achieved by specifying lightweight and durable alternatives to natural slate roof tiles, such as concrete. As the amount of quarrier aggregate used is significantly reduced when compared with natural slate, the impact on the surrounding landscape is effectively minimised, whilst the manufacturing methods for concrete tiles also requires less energy throughout the production process. The result is a roofing tile that has much lower embodied carbon, but does not compromise on the quality, aesthetic or performance benefits associated with other materials. To support specifiers in taking the principles outlined within the Future Homes Standard one step further, Forticrete has substantially reduced the embodied carbon within its popular Gemini® concrete roof tiles by using Lafarge Cement’s SustainaCem. The result is the creation of a more durable and environmentally friendly tile that delivers superior longevity and minimises product waste. Due to Gemini’s® innovative ‘double cambered’ design, the interlocking roof tile also require fewer tiles to cover the same area, when compared to a conventional double lapped plain tile.

"THE FORTICRETE SL8 LARGE FORMAT ROOF TILE DELIVERS SUPERIOR COVERAGE BENEFITS WHEN COMPARED WITH TRADITIONAL LARGE FORMAT ROOF TILES, WITH A 20% REDUCTION IN THE NUMBER OF TILES HANDLED AND LAID." 62

BuildingProducts.co.uk • May/June 2021

ROOFING This further reduces the environmental impact of a new build development, whilst simultaneously minimising overall build costs, as the speed of installation is significantly increased, whilst the volume of materials required is subsequently decreased. The need for building products that accelerate the rate of building is another leading consideration that specifiers are addressing in relation to the construction of new build properties, as 2020 saw unprecedented disruptions to the industry. This was due to lockdown causing a significant backlog in the construction of new developments, which was swiftly followed by a rapid increase in demand caused by the extension of the Stamp Duty holiday and the confirmation of the Affordable Homes Programme. To support an amplified rate of building, without compromising on the sustainable credentials of the property, large format concrete roof tiles are rapidly growing in popularity.

Russell Roof tiles specified for unique development in the South

The Forticrete SL8 large format roof tile delivers superior coverage benefits when compared with traditional large format roof tiles, with a 20% reduction in the number of tiles handled and laid, significantly increasing the efficiency of installation.

Russell Roof Tiles, which is seeing significant growth in the south of England, has been specified for a unique £13.5m residential project in West Sussex.

However, aesthetics and durability also remain leading considerations throughout the initial design and specification stages, as specifiers are increasingly searching for new roofing materials that offer an enhanced or unique visual appeal, without compromising on quality and energy performance. This includes large format concrete roof tiles that feature a thin leading edge, to not only improve building processes and reduce the quantity of building materials required, but provide enhanced visual effect that supports the creation of unique yet cohesive properties across an entire development. Again, the Forticrete SL8 has considered this newly attractive feature, offering both large format and thin leading edge in a single package. As technology continues to advance, the ability to create a tile that replicates a natural aesthetic at a lower cost, combined with enhanced installation efficiencies, is paving the way for a new generation of concrete roof tiles that reflect the principles outlined within the Future Homes Standard, whilst helping to meet the rise in demand for new build properties. 

Leading British housebuilder Taylor Wimpey has joined forces with other housebuilders in the area, including Cala Homes to develop a collaborative community known as Shopwykes Lakes. A number of housebuilders have specified Russell Roof Tiles for the community scheme and once complete over 500 homes in the development will feature its Bute roof tiles. Shopwykes Lakes is unique in the fact it is the only lakeside development in Chichester – designed around two natural lakes which are the focal point of the residential area. The Bute has grown in popularity since it was launched in 2016 and Taylor Wimpey has specified Bute tiles on a number of developments in the south of England. Russell Roof Tiles is now the only manufacturer to produce this colour tile in the UK. The thinner leading edge tile is available in seven colours and offers the strong and long-lasting benefits of concrete, even in severe weather conditions. Bute has now been used across various developments in the South such as Berkshire, Essex, Oxfordshire, Hertfordshire, Surrey and Hampshire. Like all the firm’s Natural Range, Bute is manufactured using 15% less raw materials than a standard flat interlocking tile, meaning that environmentally a “greener” choice is delivered to site on fewer pallets and therefore reducing transport and packaging. James Pendleton, Regional Sales Director at Russell Roof Tiles, said:“The Shopwykes Lakes development demonstrates how popular the Bute is becoming in the South as it has been specified with several leading housebuilders, including Taylor Wimpey, Cala Homes and most recently Redrow Homes – as the aesthetically pleasing and affordable option.” May/June 2021 • BuildingProducts.co.uk

THREE THINGS TO CONSIDER WHEN SPECIFYING ROOF ACCESS HATCHES

hen choosing roof access hatches for commercial or residential projects, there are a number of factors that must be addressed at the initial design stages in order to not only achieve a successful specification, but also deliver safe and sufficient access for the entire lifecycle of the building. Here Tony Stevens, Technical Estimator at Bilco UK, discusses which factors should be taken into consideration when selecting Roof Access Hatches:

PURPOSE FOR ACCESS Whether for the education, healthcare, leisure or commercial sectors, roof access hatches are required to provide permanent and secure access to the roof area. In order to make sure you’re choosing the correct system to meet your project’s unique requirements; you must first identify the main reason for requiring access to the roof. Is it purely for maintenance reasons? Or will a safe means of access also be required for the regular installation or removal of equipment from the roof? Here, you should also identify what tools and equipment will need to be transferred through the access hatch, or whether it will just be the individual themselves that is conducting the necessary work.

FREQUENCY AND PRODUCT SPECIFICATION Once you have established your reason for requiring safe access to the roof, you will then be able to make an informed choice regarding which roof access hatch and corresponding ladder system is best suited to meet the needs of your project. It is important to specify the correct Roof Access Hatch and Ladder combination to ensure that access from the ladder, through the roof access hatch, is as safe as possible. For example, a small roof access hatch should be accessed via a fixed vertical ladder, which is also the most suitable option for projects where space is limited. Alternatively, if you use a companionway ladder, or a retractable ladder, the roof access hatch length must be extended to around 1500mm in order to provide for easy and safe access. However, here it should be noted that a minimum head clearance of 120mm is required and that the maximum single climb is no more than three metres, in accordance with BS4211-7.2. Regardless of the size of the roof access hatch, the system should be operated easily and safely with one hand, in accordance with the requirements outlined within the Manual Handling Regulations, enabling the individual to maintain three points of contact with the fixed ladder. During the installation process, the ladder must be positioned opposite the hinge to ensure safe and unobstructed access. If access to the roof is required on a regular basis for professionals that will have to transfer tools and equipment through the hatch, a Fixed Staircase Roof Access Hatch, also known as a Service Stair Roof Access Hatch, should be specified with a Companionway Ladder or a Fixed Staircase. It should here be noted that the roof

BuildingProducts.co.uk • May/June 2021

hatch must be sufficient to maintain a head clearance of 2000mm, as detailed in Building Regulations Part K.

BESPOKE REQUIREMENTS To ensure all the criteria are successfully met, you should also consider whether a custom made roof access hatch should be chosen to ensure each of these areas is adequately fulfilled. This includes options such as Bilco UK’s SKY Flatglass, which functions as both a Roof Access Hatch or a Smoke Ventilator, and is supplied with a clear, translucent lid to enable natural daylight into specific areas of the building, without impeding the functionality and accessibility of the hatch. Increased access opening sizes or double leaf configurations should also be explored where access is required for larger items of equipment or tools. Motorised options also allow the individual to safely maintain contact with the ladder when entering or exiting the hatch. By working closely with a manufacturer at the initial stages of a project, you can ensure that each of these important factors have been adequately considered and catered for. Regardless of the project type, all installations should be subject to individual Risk Assessments. Comprehensive training should also be provided for all professionals, supported by Method Statements regarding safe and correct use of the access solutions installed. 

A superior SIP panel for the 21st century

he idea of a structural insulated panel (SIP) began in the US in 1935 when engineers speculated that plywood and hardboard sheathing could take a portion of the structural load in wall applications.

exceptionally durable, lightweight, and adaptable sandwich panel provides a building system that delivers an affordable alternative form of construction.

By the 60s, rigid foam insulating products became readily available resulting in the production of structural insulated panels as we know them today.

The modular panel, comprising of two galvanised welded steel wire meshes joined by connectors and enclosing an expanded polystyrene sheet shaped as required, is assembled, and sprayed with shotcrete on site to complete the structure and provide weatherproof properties.

Fast forward to today, and SIPs are now made with a variety of structural skin materials, including oriented strand board (OSB), treated plywood, fibre-cement board, and metal and offer a high-tech solution for buildings.

With the technology, which was developed by EMMEDUE in Italy, being used to construct more than one million buildings worldwide, GLBs MD Chris Williams has seen first-hand how the system has been vital in enabling buildings to be built quickly and sustainably.

And with the drive to build faster, cheaper and, most importantly, greener, one SIP panel ticks all three boxes.

“Architects and developers being under pressure to reduce construction costs and build-time is nothing new,” said Chris.“But with the increasing pressure to consider climate change, and targets to hit for the Future Homes Standard and net-zero carbon emissions,

innovative construction methods like our system are being adopted.” An advanced system The material science behind the system, which is lightweight, but has a compression strength of at least 10 times that of a breezeblock, is what sets it apart. The panel is more than 90% air, providing the best carbon footprint per U value, while just 80mm of GLB’s low carbon concrete provides a structural wall with a carbon footprint of only 33kg/m2. When you consider a brick/block wall insulated to the same U-value with mineral wool would be 177kg/m2 then the difference is massive. “Each home built using the system can reduce energy expenditure and carbon emissions by at least 65% compared to traditional builds when built to passive house U-values but you notice the difference even with standard building regulation compliance,” said Chris, who for the last 16 years has had the benefit of living in a home built using the technology. “A zero-carbon economy will require energy-efficient manufacturing of building materials and energyefficient structures, which means the construction sector has opportunities over the short and long term to reduce carbon emissions through the choice of materials with a low environmental impact.” GLB can adapt its core material to other insulant systems, including EPS, mineral wool, cork, and foamed glass if required by client specification or building regs. Finished panels of rigid or mineral wool insulation both provide more than 120 minutes of fire protection (REI120). The versatile panel allows for many different design options, from curves to geometric shapes and balconies to roof top expansions, and can be used for external walls, any internal loadbearing walls, flooring and landing, roofing, and staircases. “The panels can be used for anything, meaning a whole house can be constructed using the same building system,” said Chris. “And thanks to our curved panel, which can be made to almost any size and is unique in the world of construction, there are no design restrictions – if it can be drawn, it can be made.”

"EACH HOME BUILT USING THE SYSTEM CAN REDUCE ENERGY EXPENDITURE AND CARBON EMISSIONS BY AT LEAST 65% COMPARED TO TRADITIONAL BUILDS WHEN BUILT TO PASSIVE HOUSE U VALUES BUT YOU NOTICE THE DIFFERENCE EVEN WITH STANDARD BUILDING REGULATION COMPLIANCE." Chris Williams

Simple to build The systems simplicity is its key when it comes to cutting costs and construction time. The lightweight panels, which weigh no more than 5kgs per square metre before concrete coating, can be carried on site by hand, eliminating the need for cranes and other external equipment, and they can be easily installed using on-site tools in all-weather conditions. A single truck can deliver all the materials needed for one house, Using the GBL system reduces construction times by as much as 50% compared to traditional building methods and a complete watertight house can be built in just five-six weeks. A raw structure made with the system can cost up to 40% less than a traditional structure of comparable market value and, as panels are machine made and assembly processes are optimised, there is also big savings on labour costs. Chris said:“Our system makes house building as easy as possible for contractors, installers and everyone else involved in the process. By building a whole house or houses using the same building system, it optimises the supply chain, shortens construction time and reduces labour requirements.” The perfect solution From its Corby-based factory, GLB can provide up to 4000m2 of kit per day and have the capacity to supply developers, housing associations and local authorities material to build 3,000 houses a year. Approved by the Government as a MMC, the system can be used in precast structures, onsite in-situ cast structures and on site in-situ spray concrete depending on the project and clients’ needs. “Convincing those in the decision-making process, such as heads of lending and quantity surveyors of the systems worth has been challenging but that is changing rapidly, and it has started gaining some real traction in the last six months,” said Chris. “We have doubled the number of projects we are quoting and providing input for and they range from larger projects such as high-rises and smaller developers to individual dwellings and the self-build market. “And with our digital manufacturing capability, we can adapt to regulation changes with ease, one example being the creation of our hybrid panel which removes the combustible element form external walls above 18m yet still provides an insitu build option which is important for us because it provides options to our contractors using techniques they already know.” The design capabilities, exceptional strength and energy saving capabilities make the GLB system a twenty-first century building material for high performance buildings.  May/June 2021 • BuildingProducts.co.uk
