FIELD: building materials.
SUBSTANCE: invention relates to sandwich panels that can be used in internal partitions, outer walls, on facades and roofs. A panel contains the first outer shell consisting of a metal outer layer, at least two heat-insulating layers, each of which consists of rigid polyurethane foam or polyisocyanurate foam, and at least one reinforced layer located at a distance from two outer shells and between two heat-insulating layers; at the same time, the reinforced layer is made of drywall or fibrocement slabs, and the panel additionally contains the second outer shell on the opposite side relatively to the first outer shell.
EFFECT: invention provides for the creation of reinforced sandwich panels with good heat-insulation.
