Daren Drage of Exedra d.s Drage has designed an innovative speculatively built 'Eco' house at Redland in Bristol, illustrating that green houses can be profitable for the developer as well as environmentally friendly. Built using mainly renewable or recyclable materials, Drage chose pmf's Seam-Loc roof panels produced from Colorcoat hp200 steel - a combination more commonly found on commercial and industrial buildings. 'Steel is one of the world's most recycled materials - it was an obvious choice,' says Drage. Seam-Loc's clever clip fixing design eliminates through-fixings in the cladding sheets, making leaks virtually impossible. It can be installed on roofs as shallow as 1.5degrees pitch. The performance of the roof covering is guaranteed under the Confidex warranty which is fully transferable if building ownership changes.
