BUILDING HEAT INSULATION MATERIAL, BUILDING HEAT INSULATION METHOD, RECYCLING METHOD FOR BUILDING HEAT INSULATION MATERIAL, AND SPRAYING DEVICE FOR HEAT INSULATION MATERIAL

摘要

To provide means having high workability and recyclability for preventing combustion of a building heat insulation material.SOLUTION: The building heat insulation material comprises at least: a protection part 20 in which a part or the entire surface of a heat insulation material is made of a foaming-in-place urethane resin composition having at least quasi-noncombustibility in a heat generation test compliant with ISO-5660; ad a base 10 in which the remaining part of the heat insulation material is made of a foam plastic composition having fire-resistant performance lower than the protection layer, and the base 10 and the protection part 20 are integrated.SELECTED DRAWING: Figure 1
