Facing panel of composite material for producing a façade covering.

摘要

The cladding consists of an outer layer (2) of polyester which is polymerised at high pressure, is rot-proof and self-cleaning, and an inner layer (3) of expanded polystyrene which is stuck to the back of the outer layer. The upper and lower edges of the outer layer are shaped so that each successive row engages with the one below it, i.e. by having a recessed upper edge (8) which receives the offset lower edge (9) of the next row to ensure that the outer surface is flat, regardless of faults in the support. The upper edge of the outer layer is used to receive fixings (13) which are concealed by the next row. The channel also has water drainage channels and outlets. The polyester used for the outer layer of the cladding is pref. made from 18 - 23% polyester resin. 7-10% glass fibres and 60-70% mineral filling, with colouring or other additive to ease separation from the mould. <IMAGE>
