Patent ID: 8708098

Claim:
A support membrane devised to be used with a covering installed onto a carrying surface, said support membrane comprising: a base layer made of fibers and devised to be positioned onto the carrying surface in order to absorb sound waves and to level irregularities of the carrying surface; a positioning layer made of fibers, said positioning layer being devised to receive the covering and act as an anchor in order to reduce the tension effect on the covering when the covering is made of wood, ceramic or placopaster, whether vertical in the case of a wall, or horizontal in the case of a floor; and an anchoring membrane acting as a vapor barrier, wherein said anchoring membrane is applied in a liquid form by thermofusion simultaneously between and onto both said base layer and said positioning layer thereby connecting said base layer and said positioning layer and providing an integral cohesion of said base layer and said positioning a layer, said anchoring membrane providing a mechanical support and a non-delamination of said base layer and said positioning layer.
