FIELD: construction.
SUBSTANCE: group of inventions relates to a rigid panel for construction with a central foamed layer and a resin coating, as well as to a method for production thereof. Rigid panel of multilayer type for construction is made of functionally interacting central layer of polystyrene XPS or expanded polyurethane and an outer layer of a given two-component polyurethane resin. Layers are combined as a whole and in a symmetrical manner with two opposite surfaces of the central layer.
EFFECT: layer on each surface is directly formed on it with equal thickness and composition for obtaining a rigid panel exhibiting high resistance to bending, impacts, moisture and also configured to serve as a base for direct setting of adhesives or cement mortars; panel can be used as an element for erection of walls, walls with filling, floors or base floors, it serves as the main one for direct laying of tiles or plasters and is suitable for wet rooms, as is the case with bathrooms, saunas, laundry rooms or kitchens.
