A polymer membrane building skin is assembled from prefabricated panel assemblies 101-108, resulting in an appearance similar to a traditional lead roof. Each panel comprises a flexible membrane having a weather surface and a rear surface, the membrane rear surface being bonded along at least one edge to a strip 140/142 relatively rigid material, such as polymer-coated steel. The panel has an un-bonded portion 254 which can be exposed temporarily to allow fixing onto a supporting structure, the un-bonded portion and fixing 170 being re-covered by the membrane in the finished assembly. Side edges of membrane panels overlap and may be welded. Sealing strips 324 are provided at the lower edges for welding to the panel below. Various fixings incorporating weldable membrane material are described for attaching accessories such as capping strips 812 and other accessories to the completed skin, for cosmetic or other purposes. |
