Abstract

A heat and sound insulating panel is manufactured from a base comprising a flat sheet of expanded polystyrene having a density of between 14 and 45 kg/m<3> to which is applied a coating comprising a layer of wood chips or vulcanised rubber particles having a hardness of not more than shore 60 and a thickness of between 0.4 and 0.6 times the thickness of the base. The method of manufacture of the same comprises the following stages: - compression of a base comprising a flat sheet of expanded polystyrene having a density of between 14 and 45 kg/m<3> in such a way as to break at least part of the small internal cells in the polystyrene, - spraying a hot-melt adhesive based on a two-component polyurethane onto the surface of the sheet, - applying at least one coating of vulcanised rubber particles having a hardness of less than shore 60, - gauging and flattening with a roller, - covering the layer of rubber with a water-based lacquer, - evaporation with hot air. <IMAGE>
