A large area wall element of lightweight sandwich design for prefabricated buildings has a weatherproof outer layer which is formed by facing panels which are fixed to a foamed plastic layer by means of an adhesive layer in which fiberglass matting is embedded, the foamed plastic layer being glued to the supporting structure of the wall element. This wall element can be fabricated completely at the factory and transported from there to the construction site. It offers good thermal insulation and good weatherproofing. Through selection of the facing panels, a wide variety of effects can be achieved. In particular, facing panels of stone or stoneware, including brick, are suitable. The impressing of a masonry wall can be achieved by means of bricks. However the facing panels can also be arranged in distinct areas defined by means of wooden elements arranged in the form of framework. In this connection, the wooden elements can either be fixed directly to the supporting structure of the wall element or to the foamed plastic layer by means of the adhesive layer.
A load-bearing, transportable outer wall of a prefabricated building comprising a panel-like supporting member having an outer continuous surface, and at least four outer layers, said supporting structure and said layers arranged in a sandwich design, the outermost layer comprising at least two weatherproof facing panels, a panel-like layer of foamed plastic, a first adhesive layer located between and adhering the outermost layer to the foamed plastic layer, and a continuous fiberglass matting embedded in said first adhesive layer, such that said matting is located within said first adhesive layer, said foamed plastic layer having its innermost surface glued to the outer continuous surface of the panel-like supporting member by a second adhesive layer, and its outermost surface joined to said continuous fiberglass matting by said first adhesive layer, thereby to locate said foamed plastic layer between said supporting member and said matting.
