Disclosed is a studded membrane for underfloor heating, of the detaching membrane type which also acts as a support for the laying of electrical conductors. The studded membrane has one waterproof plastic sheet coupled to one base layer for anchoring the membrane on the laying plane, with studs which protrude from the membrane-plane and are arranged in a matrix with regular center to center distance in such a way to obtain hollow and continuous spaces among them in the form of corridors. A heating cable is retained and placed among the studs. In particular, adhesive curbs are provided to retain the heating cable and are made up of a glue laid in strips on the membrane-plane, in correspondence with the corridors among the studs acting as laying corridors for the glue.

SEPARATING MEMBRANE WITH IMPROVED ADHESION AND PROCESS FOR OBTAINING IT
Separating membrane (10) of plastic material, made up of a bossed and waterproof sheet (100) which is coupled with a permeable base layer (101); the bosses (102) are of the cylindrical type with a double diameter (D1, D2) and have such a shape and arrangement as to feature improved adhesion on both faces (110-111). The invention increases the gripping of the adhesive in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber (103) there is an internal crown (104), which divides it like a necking (D2) into two superimposed compartments (105-6) having the same diameter (D1), wherein the first compartment has a depth (H1) amounting to at least 1/3 of the total (H). The invention also relates to the production process for obtaining said membrane (10).
