<p>The present invention provides a foamed resin laminate sound insulation board capable of exhibiting sound proofing performance, which is free from restrictions of shape, applicable place and weight, thinned as the whole laminated plate to enhance plastic workability such as press work, and provided with sufficient vibration damping performance in a final using state after heating foaming process. This foamed resin laminate sound insulation board 1 is a laminated plate comprising at least an unfoamed foamable resin 3a to be foamed at a foaming temperature by heating and a hard plate 2. <IMAGE> <IMAGE></p> |
