BRIGGSAMASCO has been shortlisted in this year’s SPRA Awards for a Passivhaus roof installation at Perth High School.
The awards celebrate excellence, innovation and sustainable ingenuity in the single-ply roofing sector.
The roofing and waterproofing contractor has been named a finalist in the Sustainability category for its work at the new £80 million Perth High. The facility is one of the first and largest Passivhaus schools in Scotland.
Tony Lawther, MD at BriggsAmasco, said, “Congratulations to the teams involved in the Perth High School Passivhaus roof delivery. A SPRA awards shortlisting is a fine achievement in itself.
“It’s particularly pleasing to be recognised in the Sustainability category. Our development of smarter, more energy-efficient products and practices is not only key to us achieving our long-term environmental goals; it’s our contribution to a less impactful built environment.”
BriggsAmasco was selected by main contractor Robertson to install Perth High’s main roof to a Passivhaus Classic requirement of 67kwH/㎡/annum. The £2 million project covered a circa 6,000㎡ roof area and installation comprised a Bauder Thermofol Single Ply Warm Roof system, steel decking, perimeter drip flashings, permanent edge protection, and a permanent walkway.
Managing the roof’s complex changes in level required accessing key plant areas, demanding a ‘rigorous’ approach to Passivhaus compliance. To prevent thermal bridging at these junctions, BriggsAmasco partnered with Robertson and NORR Architects to design a continuous, two-layer 320mm insulation system.
The intricate detailing was initially verified using a 50㎡ mock-up at BriggsAmasco’s Cumbernauld facility to ensure the stringent standards were achievable. The solution was described as ‘critical’ to securing the building’s high-performance, fully sealed thermal envelope.
Tony added, “The Perth High School project showcases our teams’ ingenuity in overcoming complex and challenging issues to fulfil a client’s precise waterproofing and thermal requirements. The teams are an asset to BriggsAmasco and the roofing profession as a whole.”
Winners will be announced at an awards lunch on July 1 in Birmingham.
