Hollowford Centre, Peak District
Challenging and inspiring young people is being achieved holistically at a charitable trust’s centre of excellence, with help from the roofing membrane….
The Lindley Educational Trust delivers outdoor activity programmes for young people under the age of 25; growing demand for its resources at its 40+ years-old Hollowford Centre has prompted the Trust to invest in an upgrade and extension to the main building, that, even against the backdrop of the Peak District scenery, delivers a ‘wow factor’ for the 8000+ visitors each year.
The front façade has been extended, and a corridor converted and remodelled into a modern reception area featuring a new, curving flat roof and glass floor to ceiling. FCB Roofing, for main contractor TC Williams, constructed the new roof, turning to leading single ply membrane manufacturer Protan.
The new roof over both the entrance canopy and the new extension, linked with a gutter, comprises plywood decking, a vapour control layer loose laid and sealed, topped with insulation and covered with Protan SE1.2mm(?) dark grey membrane.
For the main roof areas, FCB mechanically secured the Protan membrane through 120mm thick insulation with thermally-broken fixings to achieve a U value of 0.18w/m2K to the main roof areas, further strapping and welding the perimeter to address wind uplift arising from the site’s exposed location. The gutter valley between the canopy and new extension was created by mechanically fixing Protan SE membrane over 70mm thick insulation.
“We needed more space, as more people than ever are accessing our provisin, and the old building was in need of repair,” explained Lindley Educational Trust’s head of centres Mark Williams. “We wanted to create a wow factor, a good first impression. The modern image and curved edge of the new roof look great!”
Protan SE single ply membrane, available in 1.2mm, 1.6mm and 1.8mm, is developed to cope with even the most extreme weather conditions without detriment: it is certified to ≤ -30°. Hot-air welded at joints and mechanically fixed to the roof, the membrane achieves durability in excess of 30 years, with air leakage controlled/minimised in line with latest Building Regulations.
Protan SE membrane is also certified to deliver, and potentially surpass, the energy efficiency requirements laid down in Approved Document L, and, under the Green Guide, achieve a A+ rating.
Established some 75 years ago, and still privately-owned, Protan is one of the top 3 membrane manufacturers in Europe. Manufactured at the company’s headquarters in Norway, Protan has roofs that have been in place for 30+ years without performance-affecting degradation. A full support service, from NBS specification and in-house CAD design through to technical advice is provided from Protan UK’s Warrington office.
