The awards celebrate the very best in the industry across all roofing disciplines, recognising outstanding workmanship, problem solving, environmental qualities and contribution to the built environment.

Progressive’s impressive work on The Dunes, which was completed in August 2018, secured their place as one of 13 category winners.

The Dunes project also triumphed at the annual RICS Awards 2019: South West, supported by headline sponsor Sika. Coming out top in the Residential Property category, winners were announced at a ceremony on 22 May 2019 at Bristol Marriott Hotel. The development was labelled exceptional by judges, who were impressed by the project’s innovative design, high quality construction and consideration for sustainability.

Working on a site just 10 short metres from the beach, Progressive was tasked with installing a long-lasting roofing system robust enough to withstand the South coast’s often extreme wind and rain, while matching the luxury aesthetic of the build.

Having suggested Sika Sarnafil’s single ply membrane to the architect Stride Treglown, the team worked closely with Sika Sarnafil and the main contractor Acorn Blue to ensure a high-quality and cost-effective finish.

Wind uplift calculations were provided by Sika Sarnafil to the contractors, which suggested the product be mechanically fixed to ensure the roof was able to resist the formidable weather. With a combination of Sarnafil’s S327 18 EL Lead Grey single ply membrane, plus Sarnavap vapour control and SarnaTherm insulation, the outcome was a robust roof that met the requirements of the project.

The skilled workmanship and clever design saw the roof secure a 20-year guarantee, which covered all Sika Sarnafil products used in the installation.

Progressive’s Levi Stephens, dedicated contracts manager for the project, comments on the Roofing Awards win: “One of the most prominent design features on the roof were Sarnafil Decor Profiles, which were used on the steeper pitched roofs and the beach houses in order to mimic a standing seam roof. These were a challenge to execute both in terms of the roof being pitched and the windy coastal conditions. However, having used Sika Sarnafil single ply many times before, we were confident in the product specified and are over the moon to see the end result recognised with such a prestigious award.”

Alistair Speirs, Area Technical Manager at Sika, added: “We’re thrilled to see this build excel in the Roofing Awards’ Single Ply Roofing category. The Dunes was a 14-month project challenged with unforgiving coastal weather and high expectations in terms of quality workmanship. However, the combination of Sika products along with the expertise of both the contractors and our technicians involved in the installation resulted in a stunning finish that will keep the residents of The Dunes warm and dry for many years to come.”

The Pines Primary School in Red Lodge has been constructed to provide a flexible, adaptable and sustainable space for education, with the help of Kingspan Kooltherm K15 Rainscreen Board.

The purpose-built structure, designed by Concertus Design & Property Consultants, has been carefully planned to meet today’s educational demands, cope with changes in the future and reduce the environmental impact of the school. The new building has been constructed by contractors, Morgan Sindall Construction, and offers specialist classrooms, practical areas and administration facilities, with the flexibility for growth as the school’s pupil intake increases. To ensure the new building achieved a premium level of thermal performance, 1600 m2 of Kingspan Kooltherm K15 Rainscreen Board was installed in a 50 mm thickness, helping to create a more comfortable learning environment, which can inspire and stimulate.

All new school developments in Suffolk require adoption of a sustainable building approach and, to this end, building materials were carefully chosen to both meet the design requirements and ensure maximum efficiency for the building’s life cycle. The school was designed to target a wall U-value of 0.19 W/m.2K, meeting best practice requirements. Concertus Design & Property Consultants commented:

“Sustainability needed to be considered early in the design so best practice could be embraced before, during and beyond the construction phases to reduce the immediate and long-term environmental impact of the new school.”

Utilising Kingspan Kooltherm K15 Rainscreen Board within the façade system allowed flexibility in the design process, as it is suitable for use behind a range of cladding options, including the timber façades chosen for the school, whilst maintaining the high levels of insulation required for the project.

The Kingspan Kooltherm K15 Rainscreen Board features a fibre-free rigid thermoset phenolic core and offers thermal conductivities as low as 0.020 W/m·K. This allowed the U-value to be met with a slim external wall construction.

In addition, all Kooltherm, Therma and KoolDuct insulation products and cavity closers manufactured at Kingspan Insulation’s facilities in Pembridge and Selby are certified to BES 6001 (Framework Standard for the Responsible Sourcing of Construction Products) ‘Excellent’. They are also manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Recent redevelopment of the food court at Kings Mall Shopping centre, on a five-acre site in London’s Hammersmith area, exposed up some interesting and complex challenges.

As part of the ongoing development, the new residential apartments above the shopping centre were being adversely affected by light pollution and lack of privacy from visitors looking through the food court atrium.

To solve this problem, owners and developers Schroders decided to install Kalwall translucent cladding around the whole of the atrium. This screened the external courtyard above, thereby mitigating the issues around privacy, while maintaining the maximum levels of interior daylight.

Installed in a Verti-Kal pattern, the Kalwall panels complement the industrial feel of the redevelopment and its hard concrete and stone surfaces, while providing several benefits for shoppers and residents alike.

This project perfectly illustrates the advantages of Kalwall over traditional glazing. Here it offers complete line-of-sight protection, maintaining privacy for the residents and controlling light pollution, while bathing the interior with diffused daylighting, regardless of the weather. The panels are lightweight but very durable with excellent resistance to impact and scratching. They are also vandal resistant with good protection against windborne debris.

In addition, Kalwall’s insulating properties mean that U-values down to 0.28 can be achieved while daylight is driven deeper into the interior space below, thereby reducing energy costs for both artificial lighting and temperature control.

The exterior face is colour stable and includes a UV resistant, self-cleaning surface. This means that normal rainfall helps to keep the surface free of dust and dirt while at the same time retaining the original colour during the weathering process. All this helps to reduce the costs of maintenance and cleaning.

The Kingspan TEK Building System is providing a precise offsite building solution for one of the country’s largest Passivhaus developments in Bowthorpe, Norwich.

Rayne Park is the first development by Norwich Regeneration Company, wholly owned by Norwich City Council, and will include a mixture of private and affordable housing. RG Carter are constructing 112 of the 172 properties on the development to the Passivhaus Standard. The internationally renowned energy efficiency standard requires buildings to be both highly insulated and airtight.

After reviewing the market offering to achieve the demanding fabric requirements of the Passivhaus Standard, it was concluded that the Kingspan TEK Building System was the best solution for the project on the basis of technical specification and value offered.

Kingspan TEK structural insulated panels (SIPs) feature a high-performance insulation core sandwiched between two layers of OSB/3. The panels were fabricated to the site’s requirements by Kingspan TEK Delivery Partner, Kingspan Timber Solutions. This offsite fabrication process allowed the panels to be factory cut to the specific design requirements, minimising waste and allowing an accurate, fast-track erection process on site.

Kingspan TEK Building System panels can achieve U-values of 0.20 – 0.17 W/m2.K, or better ‘out of the box’. With the addition of an additional layer of insulation, the site team were able to further improve the thermal performance of the external walls – achieving a final external wall U-value as low as 0.09 W/m2.K.

The panels’ proprietary jointing system not only allows continuity of insulation at junctions but, in combination with the OSB/3 facings, also helps to create highly airtight buildings. Once the outer shell was erected, RG Carter installed an additional internal membrane and applied airtight tape to all joints, resulting in a final air leakage rate of from 0.37 to 0.56 air changes per hour @ 50 Pa. This highly airtight design necessitates the use of a mechanical ventilation heat recovery system (MVHR) to maintain a constant supply of fresh air within the properties. MVHR units use the heat from outgoing stale air to warm incoming fresh air, further reducing the property’s heating demand and creating a fresh and comfortable indoor environment.

It is expected that the properties will have a heating demand of just 11 kWh/m2a and a primary energy requirement pf 77 kWh/m2a. This heating demand is around 10% of that of an average home (estimated to be 140 kWh/m2/yr ), making them both cheap to run and comfortable to live in.

Sika supplied the corrosion-resistant repair solution as part of a huge refurbishment involving six social housing tower blocks.

The Brentford Towers in west London form an imposing cluster in an estate within the capital’s Hounslow district. Built between 1968 and 1978, the towers contain 88 homes in each of 6 twenty four storey point blocks with exciting views over the Thames and West London. Over time, the structures’ concrete façade had become cracked and spalled in areas, leading to Hounslow Council implementing a repairs programme as part of a major overhaul of the buildings.

UK Gunite was selected to apply the Sika repair system on behalf of the project’s main contractor, Engie UK. With work starting in 2017, it initially involved applying Sika® FerroGard®-903+, a surface-applied mixed corrosion inhibitor. This ingenious solution, which is based on organic compounds, is designed for use as an impregnation of steel- reinforced concrete. It is spray-applied and penetrates concrete to form a protective monomolecular layer on the surface of the reinforcing steel, thus delaying the corrosive process and the rate it progresses.

Surface cracks and spalling were then repaired using Sikagard®-545 W Elastofill. This quality product provides a crack-bridging intermediate coat, which closes pores, cavities and blowholes. It also offers excellent resistance to water ingress and damp. Sikagard®-550 W Elastic provided the concrete surface’s crack-bridging protective coating. Class ‘O’ fire-rated, Sikagard®-550 W Elastic the product is particularly ideal for exposed concrete structures susceptible to cracks and openings and the like. For the Brentford Towers refurbishment, Sika’s repair and corrosion protection solution was used across a surface area covering 25,000m².

John Dorling at Engie, said: “This was a huge project to undertake. Therefore, we required a concrete repair and protection system that was proven to be effective over large areas. The spray-applied Sika® FerroGard®-903+ was not only the best solution in terms of the protection it offered, it was also the most time and cost-effective, as its penetrative properties negated the need to break-out large areas of concrete. The Sikagard®-545 W Elastofill was also a revelation in terms of its crack-bridging ability and the light-grey finish it provided.”

Cllr Lily Bath, Cabinet Member for Housing and Social Inclusion, Hounslow Council, said “We are excited to be working with Sika, Engie and other suppliers to repair and return these iconic buildings to the landmark status that they have in West London, and to a condition that our residents deserve.”

By specifying Sika’s concrete repair and corrosion protection system, the project’s clients, Hounslow Council, have a 15-year guarantee on work involving large areas of concrete with carbonation beyond the depth of the reinforcement. Therefore, the structural integrity of these striking tower blocks has been future-proofed for the reassurance of client and occupants.

Kingspan TEK Cladding Panels have provided an offsite wall solution for a unique school and leisure campus in Littleport, helping the project to achieve excellent thermal performance within a tight construction deadline.

The £37.5 million development, designed by SNC-Lavalin’s Atkins business, co-locates a pre-school, Littleport and East Cambridgeshire Academy (LECA), Highfield Littleport Academy Special Education Needs (SEN) school and a public leisure centre. It has helped to create an inclusive community where children of all ages and abilities can develop together. To ensure the ambitious plan would be delivered in time for the new school year without compromising on the facilities’ energy performance, 142 mm-thick Kingspan TEK Cladding Panels were specified for many of the external walls.

Kingspan TEK Structural Insulated Panels (SIPs) were designed and factory cut to the project’s unique specifications by Kingspan Timber Solutions. This offsite production process minimised site waste and enabled the panels to be quickly installed onto the steel frame, ready for main contractors, Morgan Sindall Construction, to apply the final external finishes.

The highly-insulated core of the Kingspan TEK Cladding Panels allowed the project to meet its thermal performance targets. Meanwhile, the OSB/3 facing and unique jointing system minimised air-leakage through the building envelope, helping the scheme achieve a BREEAM ‘Very Good’ rating. In addition to supporting a fabric first approach and limiting the heating demand, the product’s excellent thermal performance also helped to keep wall constructions to a minimum depth, maximising the useable space within.

This was Morgan Sindall Construction’s first project implementing BIM design methods up to level 2 compliance. Utilising BIM can help with project planning, clash detection, wastage reduction, and costings. Both the 142 mm and 172 mm Kingspan TEK Cladding panels are available as BIM objects in Revit and IFC formats. Please visit for more information.

A stunning new retirement village which is due to open in the summer of 2019 has benefitted from a series of rooflight solutions from leading manufacturer Xtralite.

Wixams Retirement Village near Bedford, is owned and operated by Extracare the same company who’s Lark Hill Retirement Village was featured in the 2018 Channel 4 series of ‘Old People’s Homes for 4 year old’. The purpose built village will provide 230, one and two bedroom apartments for the over 55’s in its six acre green field setting.

“This is an exciting project that we were delighted to work on as it provides alternative lifestyles for those approaching or nearing retirement age whilst encouraging community and social engagement,” said Jim Lowther sales director Xtralite. “Great thought has gone into the design of the building and the inclusion of extensive rooflights ensures areas of the building are flooded with natural light which has been proven to improve wellbeing, especially during the darker months.”

Three sections of the construction project benefitted from Xtralite roofing solutions and its X-Span range of product. One area being the Winter Garden residential area which is a single glazed atrium over a five storey building and includes louvered ventilation.

The Village Centre roof itself benefitted from argon filled double glazed panels and was thermally enhanced to elevate the comfort of users in the central atrium of the village, the location of health spa, bar, gym and other communal facilities. Its design is visually striking creating a focal point merging visual aesthetics and practicality. This area also had smoke vents fitted to meet smoke ventilation building regulations.

Both were sizeable installations measuring over 40m in length and up to 12m in width highlighting how X-Span is entirely versatile and can encompass varieties of style, design and ventilation to fulfil both aesthetic, safety and ventilation demands and legal requirements.

Finally, the self-supporting trapezium styled entrance canopy had single glazed panels from the X-Span range creating a striking visual effect upon arrival at the village.

Mark Jarman Senior Project Manager at Galliford Try commented; “Xtralite has a good reputation in the industry for quality products and reliability and this was important to us when choosing our structural glazing specialist . Pleasingly, the process concerning Xtralite was seamless and we are very pleased with the finished elements of the project.”

X-Span remains a popular choice of glazing system. Capable of utilising glass, or lightweight lumira and polycarbonate. In the case of Wixams, glass was used for its clarity and far superior sound attenuation.

“X-Span is a great looking and very practical choice for atria, canopies and entrance ways and was ideally suited to the situations in this particular project,” said Jim. “In addition to practicality and the visual aspect it also complies with BS6399 system Part 1 (Code of Practice for dead and imposed loads), Part 2 (Code of Practice for wind loads) and Part 3 (Code of Practice for imposed/snow loads) delivering a premium solution of aesthetics and practicality.”
