AIR-BORNE AND FOOTSTEP NOISE INSULATING PANEL FOR FLOATING PLASTER FLOORS OR FLOATING WOODEN FLOORS Abstract of the Disclosure An air-borne and footstep noise insulating panel of synthetic resin foam is provided for floating floor pavements or floating wooden floors, said panel having in the interior thereof a multiplicity of voids extend- ing normal or obliquely from one panel edge to -the opposite panel edge. The panel preferably consists of a flexible closed-cell synthetic resin foam having a volume weigh-t of 15 to 25 kg/m3, especially less than 20 kg/m3, having a cell diameter of less than 0.3 mm, and exhibiting good elastic recovery. The insulating panel has a dynamic stiffness, measured according to DIN 52214, of 1 to 13 MN/m3 and also possesses the required properties regarding long-term, burning, and insulating behavior.
