PROBLEM TO BE SOLVED: To provide a heat insulation waterproof structure which is lightweight and improved in ignition resistance, by solving the problem that a heat insulation waterproof structure using a foamed resin heat insulation material as a heat insulation material layer and using a waterproof sheet or a coating waterproof material as a waterproof material layer is easy to be ignited by sparks of fire, thereby requiring a heat insulation waterproof structure improved in ignition resistance.SOLUTION: A heat insulation waterproof structure 1 is provided on a surface of an architectural structure 11 and comprises a foamed resin heat insulation material layer 21, a waterproof material layer 22 provided on the foamed resin heat insulation material layer 21, and a protection layer 23 provided on the waterproof material layer 22. The protection layer 23 contains a metal hydroxide. It is preferable that a content of the metal hydroxide in the protection layer 23 is 10 to 95 mass%. |
