Zusammenfassung:The utility model relates to a composite board for external wall heat preservation and aims at providing a novel heat preservation composite board which can effectively solve problems that in a production process of the organic heat preservation composite board, foamed gas is difficult to escape and a bubbling area exists and leads the interior structure of the organic heat preservation composite board not to be uniform, a stress concentrated area to be generated and service life of the composite board to be shortened. The heat preservation composite board comprises an interface layer and a heat preservation layer, wherein the heat preservation layer is made of organic heat preservation materials, an gas guide layer is arranged between the interface layer and the heat preservation layer and is attached to the interface layer, and the gas guide layer and the interface layer are respectively arranged above and below the heat preservation layer.
