A three-layer laminated panel comprising a polyurethane foam sheet having outer sheets bonded thereto with adhesive as well as a method for the production of such a panel. ABSTRACT A three-layer laminated panel comprising a mainly closed-cell structured polyurethane foam sheet of a density of at least 40 kg/m and having two metal sheets, at least one of which being a metal sheet which is glass enamelled on both sides, bonded thereto with polychloroprene rubber-based contact ad- hesive is produced by applying the contact adhesive to two opposite sides of the polyurethane foam sheet, drying the contact adhesive, then placing the two metal sheets both be- ing coated on one side with contact adhesive and subsequently dried, on each side of the contact adhesive coated polyureth- ane foam sheet with the contact adhesive layers facing the contact adhesive layers of the polyurethane foam sheet to form a three-layer laminated panel, then placing said panel in a suitable press under a pressure of at least 5 kg/cm2, and thereafter, if necessary, cooling the three-layer laminated panel under pressure. The three-layer laminated panel thus produced is dimension stable and weatherproof. The only Figure is to be published with the Abstract.
