Integrated heat-preserving composite board

The utility model relates to an integrated heat-preserving composite board. The composite board comprises a finish coat and a heat-preserving layer, wherein the finish coat is a square tabulate stone board or a ceramic board; the shape of the heat-preserving layer is matched with that of the finish coat, the heat-preserving layer is combined to the inner side of the finish coat, and the heat-preserving layer is a foamed ceramic or foamed glass. According to the integrated heat-preserving composite board, on the premise that fireproof flame retardance is in an A1-B1 level, surface decoration of a building is integrally constructed, and surface decoration of the building is completed while heat preservation is achieved; standard design and machining are performed, and construction procedures are reduced; a heat-preservation heat conduction coefficient is smaller than 0.06 w/m.k, and capacity can be 140-180 kg/m ; permanent heat-preserving materials are adopted, and the service life of the permanent heat-preserving materials is as long as that of the building.
