Abstract

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.
