PROBLEM TO BE SOLVED: To improve an insulation effect by bonding an insulating material which is composed of an insulating layer consisting of a heat reflection layer comprising metal flakes placed inside and a foamed plastic material placed in the lower part of the reflection layer and a ground fabric placed in the lower part of the heat-insulating layer and a top ground fabric together through the reflection layer of the insulating material. SOLUTION: A material which is in a state in which a raw material which generates nitrogen gas is mixed is set in the inside of a thermoplastic resin 19, and on it is placed a thing which is in a state in which the resin 19 is made a base, and a heat reflection material 111 of aluminum alloy flakes is mixed inside. Rolling is implemented at an appropriate temperature, and a raw material is formed in which an insulating layer 12 of foamed plastic having closed cells 122 and a heat reflection layer 11 in which aluminum alloy flakes are mixed are laminated. A ground fabric 13 which has a cloth 133 as a base and back- coated with the resin 19 is bonded to the side of insulating layer 12 through an adhesive, and an insulating material 1 of this constitution is bonded to the inside of a roof ground fabric coated with a thermoplastic resin 29 through the reflection layer 11. |
