"It was a complicated project," recalls Andy Bacon, FFR's managing director. "The roof was curved in plan, comprising three linked domed areas, and curved in elevation also. It was a three-dimensional shape that needed a versatile, three-dimensional covering."
Sarnafil's single ply system was chosen as the ideal membrane. The sweeping curves of the 7,000m sq roof, however, required two slightly different roof build-ups. Areas of concrete structural deck feature a bituminous felt vapour control layer insulated with Kingspan Thermaroof TR27 Polyisocyanurate bonded with Sarnacol 2162 PU adhesive and finished with an adhered Sarnafil membrane in G410-12EL Light Grey.
The profiled metal structural deck areas, meanwhile, consist of a Sarnavap 1000E Polyethylene vapour control layer, Sarnafil SBT tube fastener-attached Kingspan insulation and, finally, an adhered Sarnafil G410-12ELF Light Grey membrane.
