Plate for covering horizontal and vertical surfaces

A lining plate for vertical and horizontal surfaces, which comprises at least one of the following layers arranged in order from an exposed face, intended to be exposed to the exterior, to a hidden face, intended to be oriented to the surface to be lined:

• an outer decorative layer;
• a support layer comprising at least one of the following materials from the group consisting of magnesium oxide, magnesium oxide with perlite and/or vermiculite and/or cellulose;
• a self-adhesive foam material layer with a surface provided with an adhesive surface intended to be placed on the surface to be lined, the self-adhesive foam material layer being provided with a plurality of perforations;
• wherein the lining plate comprises a barrier layer or a barrier membrane to reduce or avoid water and moisture intrusion, being provided between the support layer and the self-adhesive foam material layer;
• wherein the support layer has a non-homogeneous density in its thickness, distinguishing a first thickness, following the decorative layer, and a second thickness, between the first thickness and the barrier layer or the barrier membrane, in which the density of the support layer in the first thickness is greater than the density in the second thickness;
• and wherein the support layer is provided with a reinforcing structure formed by meshes or by a fabric, being of a composite material, the reinforcing structure being located within the second thickness of the support layer.
