Sacred Heart School, Hammersmith
completed in 2015, proved to be a challenging project.
Access hatches cut into the steel. Next the whole would be laid with a fleece underlay over which the insulation would be fixed to the decking using fixings with Trocal covered washers. The Trocal membrane would then be rolled out and solvent welded to washers giving a superior, smooth finish with a long life with low maintenance.
The insulation stacked in the background was laid out and mechanically fixed to steel deck suing trocal metal discs and self tapping screws, over which the single ply membrane was solvent welded to the washers, at laps and perimeter for a seamless, waterproof roofing solution. All seams were heat checked and a seamsealant applied to all laps.
