Abstract (en)

[origin: WO2022224098A1] Rigid panel for construction (10), of the multi-layer type, made up of a central layer (101) in XPS polystyrene or expanded polyurethane, and of an outer layer (102a, 102b), structurally cooperating, in a particular two-component polyurethane resin (A1- A12, B1). They (102a, 102b) are combined in an integral and symmetrical way to the two opposite faces of the central layer (101), a layer on each face, being directly formed thereon with equal thickness and formulation, so as to obtain a rigid panel (10) provided with a high resistance to bending, impacts, damp and also able to support the direct grab of glues or cement mortars. The panel is usable as an element for building walls, infill walls, floors or subfloors, it supports the direct laying of tiles or plasters, and it is suitable for damp environments as in the case of bathrooms, saunas, laundry rooms or kitchens.
