Thermo-acoustic radiant membrane

A thermo-acoustic radiant membrane installable under an element to disengage this element from a floor on which it is installed, this membrane comprising:

• a) a radiant upper layer consisting of a metallic film provided with a lower surface coated with a layer of bitumen elastomer on which is laminated a layer of rubber granules;
• and
• b) a bottom layer provided with a top surface also coated with a layer of bitumen elastomer, the top surface being laminated on the layer of granules opposite to the radiant upper layer, characterized in that:
• the layer of granules laminated on the lower surface of the radiant upper layer having a thickness of ⅛″ to ⅝″ (about 3 mm to 16 mm);
• the rubber granules of the granules layer laminated on the lower surface of the radiant upper layer having a size ranging from 2 to 30 mesh;
• and
• the bottom layer is selected so as to be water-impermeable to act as a vapour block, also be resistant to tearing, static crushing and to tension, and to have a large capacity for stretching.

A process for manufacturing a thermo-acoustic radiant membrane wherein it comprises the following steps:

• a) deposit of a bitumen elastomer layer on a radiant layer consisting of a metallic film;
• b) laminating of a layer of rubber granules of size ranging from 2 to 30 mesh on a layer of bitumen polymer deposited on the metallic film, the granules being deposited to form a layer having a thickness from ⅛″ to ⅝″ (about 3 mm 16 mm);
• c) deposit a bitumen elastomer layer on a layer that is water-impermeable, and resistant to tearing, to static crushing, to tension and having a large capacity for stretching;
• and
• d) placing the bitumen elastomer layer of the water-impermeable layer on the layer of granules of the radiant layer to assemble the membrane by adhesion of the layers.
