Abstract

PURPOSE:To enhance the workability for heat insulation and prevent the lowering of heat insulating performance by inserting a heat insulating material having an air passage formed on one surface side between both face plates to form a heat insulating panel. CONSTITUTION:A foamed template having protruding parts 4... having substantially the same height formed by charging a synthetic resin foaming material is placed on a plywood face plate 1. After the face plate 1 having a proper space with the foamed template 3a is arranged, the synthetic resin foaming material is foamed to form an air passage forming plate 3, and an air passage 5 is formed on one side between the face plates 1, 1 by the protruding parts 4 and the face material 1. Thus, the air passage 5 is formed between one-side face plates of the heat insulating material 2 of a thermal insulating panel A, and the construction of only the heat insulating panel A suffices for the heat insulating construction.
