A method of forming an insulation product includes heating a thermoplastic material to a softened condition, and applying the thermoplastic material to a blanket of fibrous insulation material to form a laminated insulation material comprising a layer of the thermoplastic material bonded to the fibrous insulation material. The laminated insulation material is heated to soften it and molded to form it into a desired shape, and the molded laminated insulation material is cooled to form an insulation product.

Method of making an asphalt and fiber laminated insulation product

A panel for an office sound screen includes a core which includes an asphalt layer and insulation layers positioned on both sides of the asphalt layer. Preferably the asphalt layer has a thickness between 0.030 inch (0.076 cm) and 0.125 inch (0.318 cm). The asphalt layer acts as an adhesive so that the insulation layers are laminated thereto. Preferably the insulation layers are made from a fibrous glass wool insulating material having a density between 0.5 pounds per cubic foot (8 kg/m.sup.3) and 5 pounds per cubic foot (80 kg/m.sup.3). The panel further includes a cover layer positioned on at least one side of the core.
