Insulating panel for construction with grab surface

An insulating panel for construction, of the self-supporting type and which can be used as a constructive element of walls, infill walls, floors or subfloors, which is resistant to bending and to damp, and which is suitable for damp environments such as bathrooms, saunas, laundry rooms or kitchens;

• said insulating panel, suitable for supporting the laying of tiles directly applied on it, or even plasters or similar coating materials;
• said insulating panel is made up of a central layer in insulating foamed and damp-resistant material, which has a low specific weight and a high dimensional stability, such as XPS or EPS polystyrene or expanded polyurethane, and of a damp-resistant coating which is joined to said central layer on both outer faces and namely a coating on the front side and a coating on the back side, forming a sandwich structure;
• said coating being alternatively glued or adhered by means of thermo-adhesive material to said central layer;
• said is a plastic sheet having a thickness of 0.2 mm with a tolerance of +/−0.1 mm, a density of 1.1 kg/dm3 with a tolerance of +/−0.2 kg/dm3, and Rockwell hardness of D 75 with a tolerance of +/−20, wherein at least the coating on the front side has the external surface scratched by means of mechanical abrasion;
• wherein the panel has a resistance to tearing equal to or higher than 0.5 N/mm2.
