Decoupling sheet
The invention relates to a decoupling sheet that can be disposed between a floor covering and the floor and comprises a multi-layer structure that includes a central core and respective outer layers attached to larger surfaces of the central core, the central core being made of elastic foam material.
1. A decoupling sheet, which can be disposed between a floor covering and a floor, comprising a multi-layer structure that includes a central core and respective outer layers attached to larger surfaces of the central core, so that one of the outer layers ( 2 ) is facing to the floor covering and the other outer layer is facing to the floor, wherein the central core is made of an elastic foam material, and the outer layer facing to the floor comprises an outer sub-layer of geotextile material, in that the outer layer facing to the floor also comprises at least one sub-layer of waterproofing material and at least one sub-layer of reinforcing mesh arranged between the corresponding larger surface of the central core and the outer sub-layer of the outer layer facing to the floor.
2. The decoupling sheet according to claim 1 , wherein the elastic foam material is selected from the group consisting of latex, rubber, and elastic polymer.
3. The decoupling sheet according to claim 1 , wherein the elastic foam material comprises an open cell structure.
4. The decoupling sheet according to claim 1 , wherein the elastic foam material comprises a closed cell structure.
5. The decoupling sheet according to claim 1 , wherein the outer layer facing to the floor covering further comprises at least one sub-layer of waterproofing material.
6. The decoupling sheet according to claim 5 , wherein the sub-layer of waterproofing material is polyolefin.
7. The decoupling sheet according to claim 1 , wherein the outer layer ( 2 ) facing to the floor covering further comprises at least one sub-layer of reinforcing mesh ( 2 . 2 ).
8. The decoupling sheet according to claim 1 , wherein the sub-layer of waterproofing material is polyolefin.
9. The decoupling sheet according to claim 1 , wherein the outer layer facing to the floor covering comprises an outer sub-layer of geotextile material.
