Latest innovations and products in the building fabric section of the construction industry.

Kingspan Kooltherm K7 and K107 Pitched Roof Board have been installed as part of a major refurbishment project, transforming a former Victorian mill into CAT B office space for Manchester Metropolitan University.

6 Great Marlborough Street forms part of Manchester’s rich industrial heritage and sits within Little Ireland, the earliest area of Irish settlement within the city. The sensitive restoration plans make a feature of the historic building fabric, exposing the original brickwork and beams internally, whilst incorporating more contemporary elements such as building services and modern windows.

The design team prepared the fit-out using the Royal Institute of Chartered Surveyor’s SKA Rating environmental assessment method – targeting a Silver rating certificate. As part of this process, they identified an opportunity to upgrade the thermal performance of the poorly insulated pitched roof. To minimise heat loss through the roof, a construction combining Kingspan Kooltherm K7 and K107 Pitched Roof Board was installed.

Kingspan Kooltherm K7 and K107 Pitched Roof Board can achieve thermal conductivities as low as 0.020 W/m·K and 0.018 W/m·K, respectively. In combination with their low emissivity foil facing, this makes them amongst the most thermally efficient pitched roof insulation materials in common use.

As the original roof slates have been retained, the boards were cut to size by hand and fitted between and below the existing roof rafters from inside the building. This premium specification allowed the target U-value to be met with the slimmest possible construction – maximising floor to ceiling heights in the top storey spaces in the 5-floor building.

Kingspan Kooltherm K7 and K107 Pitched Roof Board are produced under an integrated management system which is certified to the highest standards including ISO 9001: 2015 (Quality), ISO 14001: 2015 (Environmental), BS OHSAS 18001: 2007 (Health and Safety) and ISO 50001: 2011 (Energy). Their insulation core is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Among the many benefits of modular construction is the speed with which a project can be completed, due to the fact construction of modular buildings can occur simultaneously with site and foundation work. By carrying out typically linear tasks simultaneously projects can reach completion 30%-50% sooner than with traditional construction methods.

The value of simultaneity in construction is also one of the benefits delivered by Performance Technology Group. By bringing together expertise and manufacturing capabilities across a wide range of disciplines, PTG are able to reduce the amount of activity required in ensuring a construction project meets fire, thermal, acoustic and other challenges.

Saving Time, Reducing Complexity

Whereas ordinarily, an architect, contractor or installer will have to liaise with multiple contacts across multiple businesses in order to source solutions for their construction project, with PTG there is a single initial point of contact. In principle, a project’s fire, thermal and acoustic requirements can be addressed in a single meeting, with PTG bringing all the necessary expertise to the table. This obviously represents a time-saving for customers (one meeting, rather than several), but there is also a subtler time-saving due to the reduction in complexity.

Complexity, particularly in construction projects, creates numerous opportunities for problems to arise. According to Sven Bertelsen, Senior Research Advisor to Lean Construction (Denmark), “Construction projects are in general rich in plan failure, delays, cost overruns and grief. Construction – along with most phenomena in our living world – must be perceived as a complex system, operating on the edge of chaos.” By reducing this complexity, PTG are able to mitigate the kinds of problems that can undermine and jeopardise the construction schedule.

System Solutions

PTG is also able to use its interdisciplinary structure to produce system solutions that would normally involve an architect, contractor or installer having to interact with a number of separate suppliers.

For example, in rainscreen cladding applications, PTG can bring together sheathing panels, the innovative Chi-Gasket cold-bridging solution (both from the Euroform arm of PTG) with a range of Open State Cavity Barriers from their AIM business to create an effective means of achieving compliance in relation to thermal performance and resistance to fire. PTG can also source and supply thermal insulation and high-performance cladding through their established third-party relationships and robust supply chains.

From Foundations to Fit-Out

PTG are involved at almost every stage of construction. They provide site protection from the very outset of a construction project. They supply both vibration isolation and thermal insulation for foundations. They are involved in every stage of the building envelope’s development, contributing to through-wall solutions to offer resistance to air, water, heat and noise transfer. They’re involved in HVAC solutions for both acoustic and thermal performance. They contribute to the acoustic effectiveness of wall, floors and ceilings, ensuring Part E compliance. Wherever and whenever, for example, an architectural technician finds themselves facing a challenge relating to the material performance of a building project, PTG will have, or will have access to, a solution.

The PTG Roster

PTG currently consists of nine businesses: AIM, CMS Danskin, Euroform, Mayplas, Ockwells, Central Refractories, IMS, Innogain and Insulslab. AIM is a manufacturer of mineral fibre and foam products, specialising in fire stop blocks and cavity barriers. CMS Danskin are experts in soundproofing and acoustic insulation. Euroform specialise in building boards and in ensuring fire and thermal compliance in building facades. Mayplas fabricate and supply a wide range of insulation materials, and specialise in highly bespoke cutting, lamination and encapsulation. Ockwells are a leading supplier of temporary site protection. Central Refractories, as their name suggests, a premier supplier of refractory products and services. IMS are experts in high-temperature insulation. Innogain are the innovators behind a revolutionary solution for through, anchor and precision hole-making in concrete. And, finally, Insulslab offer a complete foundation system, particularly for housing sites with difficult ground conditions.

Mark Fyfe, Group Sales and Business Development Director for Performance Technology Group, said, “We offer an industry-leading portfolio of trusted products, the interdisciplinary expertise to supply with confidence, and with an emphasis on highly bespoke fabrication and ambitious product innovation.”

Market-leading single ply roofing manufacturer Sika Sarnafil and two of its Registered Contractors have triumphed at this year’s Single Ply Roofing Association (SPRA) Awards.

The awards, which recognise best practice within the single ply roofing industry, saw Exeter-based Progressive Systems Ltd take home the Best Safe Working award for their contribution to The Dunes development, while Harlow-based Contour Roofing (Essex) Ltd came out top in the Best Sustainability category for their work on the Temple Farm Development.

Announced at SPRA’s fifth annual conference and awards ceremony, held at Heythrop Park, Oxfordshire on Thursday 13 June, this year’s awards celebrated both people and projects, with prizes taken home across six project categories.

Progressive’s single ply installation at The Dunes, a stunning new beachfront development in Perranporth, Cornwall, was praised by SPRA for the safety measures taken amidst challenging weather conditions.

Progressive’s Levi Stephens, dedicated contracts manager for the project, comments on the win: “We’re over the moon to have been recognised for our strong commitment to workforce safety in this year’s SPRA Awards. Installing single ply on this job was challenging, not only due to having a large area to cover, but also due to disruption caused by the coastal climate. With strong winds and driving rain, we had to ensure our workers’ complete safety was taken into account. However, by combining a systematic and thorough coverage of each roof block, high quality products and the expertise of both our roofers and Sika Sarnafil’s technicians, the roofing installation was finished on time and within budget.”

Temple Farm Development, a huge multi-roof project that saw a 34-hectare scrapyard transformed into new national headquarters for the Watch Tower Bible and Tract Society of Britain, also impressed at the awards. SPRA said the project was a clear winner in its category for achieving a BREEAM ‘Outstanding’ rating upon completion and demonstrating a sustainable approach from the outset. Additional praise was given for the project’s biodiverse green roofing system, designed to boost the local flora and fauna above the Sarnafil membrane, while the contractor was also praised for ensuring the community and environment were respected during installation, which included designing work methods to minimise noise, dust and traffic.

Contour Roofing’s managing director Jonathan Woods says: “We’re delighted that our work on Temple Farm development was recognised at the SPRA Awards. Although challenging, it was a very enjoyable development to work on and we are all very proud of the finished result. Not only did the project result in outstanding sustainability credentials, but the use of Sarnafil products helped to create a durable roofing system, save on costs and secure an all-encompassing Sika Sarnafil guarantee.”

John O’Raw, Head of Sales – Single Ply Membrane at Sika, adds: “We’re thrilled to see these projects shine at the SPRA Awards. Both are a testament to the robustness and flexibility of the Sarnafil Single Ply Membrane, which is showcased by the fact that these projects won based on overcoming challenging aspects and providing excellent sustainability benefits. We are incredibly proud of both projects, not only for excelling at the SPRA Awards, but for the hard work and dedication paid by all those involved.”

A private development for contemporary urban living in Bristol is benefiting from the latest advancement in vacuum insulation technology and exceptional thermal performance with the Kingspan OPTIM-R E Roofing System.

The Old Library is an exclusive new-build featuring 36 spacious studios and apartments in the vibrant, North Bristol neighbourhood of Cotham. The classic exterior design complements the surrounding Victorian architecture, whilst the contemporary interior provides stylishly finished living spaces. Autograph Homes, the developer, designed the building in line with their commitment to building with ‘imagination and intelligence’, combining exciting architectural features with the latest smart and sustainable technologies.

The building includes several small roof-top balconies, which are above heated spaces and offer an extension to the living areas. Installers at Youngs Roofing noted that “the need to retain low threshold heights whilst meeting the demanding U-value of 0.14 W/m2.K provided a challenge” for this project. The Kingspan OPTIM-R E Roofing System offered the perfect solution.

Kingspan OPTIM-R E comprises a vacuum insulation panel, Kingspan OPTIM-R, completely encased within a high performance PIR insulation board. With an ultra-slim 80 mm thick design, it delivers an outstanding thermal conductivity of 0.009 W/m.K.

The encasing PIR insulation board provides complete protection for the vacuum insulation panel, allowing fast installation. Utilising Kingspan OPTIM-R flex infill strips, of the same thickness, enabled installers to easily infill awkward spaces and accommodate penetrations through the insulation layer.

Kingspan Insulation provided detailed information regarding the fitting of the Kingspan OPTIM-R E Roofing System, ensuring the ratio of Kingspan OPTIM-R E panels to OPTIM-R flex infill strips was optimised. This ensured that the U-value requirements were met with a minimal construction depth, without compromising on aesthetic design.

The Abbey Hill Academy in Stockton-on-Tees is an educational establishment for students aged 11-16 with learning difficulties and disabilities.

The learning environment is never more critical for such students and since the Horizons Specialist Academy Trust became custodians of the school in 2013 refurbishments have been taking place to restore the 1970’s building.

In addition, to heating and hot water upgrades and a new roof, the striking walkway that had a rooflight canopy was replaced and upgraded to enhance the exterior aesthetics of the building. The unusual shape of the building meant that the upgraded rooflights allowed a greater degree of light into the body of the school enhancing both the practical elements and also pupil and staff wellbeing due to the increased availability of natural light.

“The rooflight canopy had definitely seen better days and was no longer fit for purpose having been exposed to the elements for so many years,” said Jim Lowther Sales Director Xtralite. “We were able to specify the latest rooflight technologies to replace the existing ones to ensure a quality restoration was undertaken.”

Four 20m x 2.2m, one 9 x 2.2m and other elements were all fitted from the X-Span range of products, a thermally enhanced self-supporting rooflight. All were double glazed with a toughened outer and laminated internal glass.

“Glass is a good choice for atria, canopies and walkways and in this situation allowed the almost exact replacement of product albeit by those that are far superior,” said Jim. “Furthermore X-Span 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.”

An inspiring new sports facility, featuring a striking Sika Sarnafil single ply membrane roof, has just been completed at St. George’s Weybridge, a Roman Catholic co-educational nursery, private day school and 6th form college in Surrey.

The exciting new architectural development has been built as part of the establishment’s 150th anniversary celebrations and includes a premiership level hockey pitch and six-court sports hall, as well as a strength and conditioning suite, dance studio and flexible multi-use areas.

Transforming the existing, functionally simple sports hall, this now beautifully designed facility has a tree canopy-like roof structure draping over the building’s internal spaces.

Designed by global architectural practice Scott Brownrigg, the roof needed to achieve 30m clear spans across the main hall and the design needed to be clever and sensitive to the fact that the site’s location sits within the green belt. It also required a flexible and durable waterproofing solution to ensure the building leaves a lasting legacy for future generations of Georgians.

Felicity Meares, Architect at Scott Brownrigg, comments on how they approached the design and specification: “We designed a bespoke freeform glulam roof that curves in multiple directions. Computer modelling software allowed us to create and control this complex roof form in virtual reality, pushing and pulling it to blend into the landscape.

“In need of a roofing product elegant and pliable enough to accommodate the complex design, lightweight enough to minimise the impact on the roof’s structure and cost effective enough to cover such a large area, Sarnafil G410-ELF lead grey single ply membrane was specified, along with Sarnavap 5000, 120m SarnaTherm G insultation board and Sika SolarMount-1. Sarnafil adhered décor profiles were also built, allowing rainfall to be interrupted and guided across the roof.”

Sarnafil worked closely with the architects and contractors to develop a specification that not only had the correct U-value, but was also compatible with the Cross Laminated Timber roof build-up and ancillary roof mounted systems used, such as Photovoltaics, Latchways, a built-in gutter and upstands for roof openings.

Roofing contractor Malone Roofing was tasked with realising the architect’s roof design. With both Malone and Scott Brownrigg having specified Sarnafil in the past, the entire team were confident that Sarnafil single ply was the right fit for this unique roof form.

Paul Hughes, Managing Director at Malone Roofing, oversaw the project. He comments on the project: “We started work on the roof in October 2018 and spent a combined total of 12 weeks on the project. Despite being faced with a particularly rainy period and a challenging design, with curves sloping up to 30 degrees in some areas, we were able to complete the roof on time and to budget.”

The architect’s vision was to create a contemporary building that would inspire students to achieve their very best. Thanks to an exceptional design, impeccable installation and Sika Sarnafil’s robust guarantees, the team have been able to achieve just that, while also ensuring this timeless design will be protected and enjoyed for years to come.

Market-leading single ply roofing manufacturer Sika Sarnafil and leading South West roofing contractor Progressive Systems Ltd are celebrating following a win at the Roofing Awards 2019.

The roof of the Dunes – a stunning new beachfront development in Perranporth, Cornwall – came out on top in the Single Ply Roofing category, which was sponsored by EJOT UK.

Hosted by the National Federation of Roofing Contractors (NFRC), TV host Sarah Beeny announced winners at a ceremony on 10 May 2019 at the InterContinental London – The O2.

Sika Sarnafil

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.”
