Abstract
A support membrane designed to be arranged with a covering that can be applied to bearing areas such as floors or even under and on concrete screeds for a floor is provided. Said membrane can also be used in the composition of ceilings and in the composition of residential walls. The membrane includes a base layer made of fibers and designed to be arranged directly on the bearing area so as to absorb sound waves and to level the irregularities of the bearing area, a vapor barrier-anchoring membrane, and optionally an underlay designed to receive the covering and provide an anchor for the finishing products. Said support membrane is characterized in that the vapor barrier-anchoring membrane thereof is applied in liquid form by hot-melting directly on the base layer and on the underlay whenever the latter is used. Said support membrane improves heat transmission by reflectivity in the room in which the wall, floor or ceiling is located, as well as guaranteeing much more efficient predefined laying of the floor thanks to the anchoring membrane contained by the former, which reduces the tension effect the floor finish can cause.
