Synthetic foam composite panel and process and apparatus for its production
The invention discloses a synthetic foam composite panel having different layers of synthetic foam for heat insulation and for sound insulation and also a skin arrangement, adhering on the synthetic foam, for water conduction and as a vapour diffusion barrier. In this case, the following features are provided in particular: The composite panel has three separate synthetic foam layers; the two outer layers (1, 3) are of the heat-insulating synthetic foam and adhesively bear on their outside, on one side in each case, a skin (7, 9); the skin arranged on the weathering side is in this case of a material suitable for water drainage and the skin arranged on the building interior side is of a material acting as a diffusion barrier; the sound-insulating synthetic-foam layer (5) is in this case located with adhesive foam-to-foam contact between the two heat-insulating synthetic-foam layers (Fig. 1). Further features provide in particular that the heat-insulating synthetic-foam layers are of polyurethane foam and that the sound-insulating synthetic-foam layer consists of an expanded polyurethane/rubber composition. <IMAGE>
