Abstract

A decoupling sheet as a support for a covering that is to be mounted on a substructure, comprising at least two interconnected layers that include a foil-type bottom layer for disposition on the substructure, and a support layer for receiving the covering. The support layer is disposed on, and connected to, the bottom layer, and is comprised of an open-pore water resistant, and non-deformable foam material that is provided with apertures that extend from the bottom layer to the opposite, free surface of the foam layer, and which are distributed over the surface of the foam layer.

Claims

1. A decoupling sheet as a support for a covering that is to be mounted on a subsurface, comprising:

at least two interconnected layers, including;

a foil-type bottom layer for disposition on the substructure; and

a support layer for receiving the covering, wherein said support layer is disposed upon, and connected to, said bottom layer, further wherein said support layer is comprised of a open-pore, water resistant, and non-deformable foam material to form a foam layer, further wherein apertures are disposed in said foam layer and extend from said bottom layer to an opposite, free surface of said foam layer, and wherein said apertures are distributed over said free surface of said foam layer.

2. A decoupling sheet according to claim 1, wherein said bottom layer is provided with a fine perforation, or wherein said bottom layer (12) is comprised of a waterproof material.

3. A decoupling sheet according to claim 2, wherein said bottom layer is comprised of a sheet of foil having a respective sheet of fleece disposed on opposite sides thereof.

4. A decoupling sheet according to claim 2, wherein said bottom layer is comprised of a sheet of paper.

5. A decoupling sheet according to claim 1, wherein said foam layer is extruded from said foam material.

6. A decoupling sheet according to claim 1, wherein said foam material of said foam layer is selected from the group consisting of polypropylene, polyethylene, polystyrene and polyurethane.

7. A decoupling sheet according to claim 5, wherein said bottom layer is applied to one side of said foam layer in a single operation at the same time as said foam layer is extruded.
