PROCESS FOR MANUFACTURING INSULATING PANELS WITH POLIMERIC FOAM AND MINERAL WOOL

摘要

The invention relates to a process for manufacturing insulating panels using a layer of polymer foam (10) and a layer of mineral wool (12). In order to obtain uniform expansion of the resin forming the insulating foam, an interface (15) is applied onto the fibrous layer of mineral wool so as to reduce the frictional resistance to the resin as it expands. Advantageously this interface may be obtained by spraying a film of the same resin as the foam.
