Abstract

A noise-deadening laminate board configured for noise deadening having a bituminous layer more than 1 mm thick, bonded to one side of a thermal insulation layer of foam, felt or the like, and an adhesive layer on the other side of the thermal insulation layer for adhesion to a component to be improved acoustically, the bituminous layer, thereby being located on the outer side of the laminate board.

Claims

1. A noise-deadening laminate board configured for noise deadening comprising a bituminous layer more than 1 mm thick, a discrete thermal insulation layer directly bonded at one side thereof to said bituminous layer with an adhesive layer, and an adhesive layer on the other side of said thermal insulation layer for adhesion directly to a component to be improved acoustically, said bituminous layer, thereby being disposed on the outer side of the laminate board.

2. The laminate board according to claim 1, wherein the discrete thermal insulation layer is made of foam or felt.

3. A laminate board according to claim 2, wherein the thermal insulation layer is formed from a thermoplastic hard foam.

4. A laminate board according to claim 3, wherein said thermoplastic hard foam is polystyrene foam or polyethylene foam.

5. A laminate board according to claim 4, wherein said thermoplastic hard foam is polystyrene foam.

6. A laminate board according to claim 5, wherein the thermal insulation layer is a 6 mm thick polystyrene foam board and the bituminous layer is bitumen F 24 of 3.9 mm thickness and a weight per unit of surface area of 6.75 kg/m².

8. The laminate board according to claim 6, wherein the discrete thermal insulation layer is made of foam or felt.

7. A noise-deadening laminate board for thermally insulating and acoustically improving a wall component layer comprising:

a bituminous layer;

a discrete thermal insulation layer directly bonded along one side to the bituminous layer with an adhesive;

the wall component layer, which is to be thermally insulated and acoustically improved, directly bonded to another side of the thermal insulation layer with an adhesive such that the bituminous layer is disposed on an outer side of the laminate board.
