止した断熱材に係るものである。[Detailed explanation of the idea] In order to reduce the transmission of radiant heat by using insulation materials on the walls and roof slab surfaces of buildings, synthetic resin foam sheets are laminated as insulation materials to create a thickness that has a good insulation effect. constitute a thick insulation material. By interposing a synthetic resin membrane with poor air permeability in the layer where synthetic resin foam sheets are laminated and bonded together, the effect of blocking water vapor permeation prevents moisture from permeating and condensing inside the insulation material. This relates to a heat insulating material that prevents an increase in heat transmission coefficient.

少ない断熱材が要求されている。 Conventionally, there have been many examples of using synthetic resin foam boards as insulation materials, such as polystyrene resin foam boards, electron beam cross-linked polyethylene foam boards, polyethylene/vinyl acetate copolymer resin foam boards, and polyvinyl chloride resin foam boards. There is. When these synthetic resin foam boards are used as insulation materials in the external roof insulation and waterproofing method of buildings, moisture generated from inside the concrete vaporizes and permeates into the voids in the synthetic resin foam, and then condenses and becomes water-resistant. This has the drawback that the thermal conductivity of the heat insulating material itself increases, and the amount of heat transmission through the heat insulating layer increases. A fact-finding survey has confirmed that the amount of water contained in insulation materials increases with time.
Therefore, thermal insulation materials with low water content are required for building roof exterior construction methods.

根外断熱防水工法に適用するものである。 The heat insulating material of this invention maintains its insulation effect for many years without increasing thermal conductivity by interposing a synthetic resin film that blocks water vapor in the middle layer of the synthetic resin foam to prevent moisture from entering. It is for the purpose of Specifically, as an example of a synthetic resin foam, a single layer of electron beam cross-linked polyethylene foam is usually about 10 mm thick, so when composing a heat insulating material with a thickness of 30 mm, three layers are used. It is a layered material. This invention is characterized in that at the time of lamination, a synthetic resin film with poor water vapor permeability, such as a polyethylene terephthalate resin film, polyvinylidene chloride film, or polyethylene film, is interposed. The insulation material according to the present invention is applied to the roof slab surface, and then synthetic polymer roofing is applied directly on top of the insulation material to form a protective and waterproof coating. This applies to external insulation and waterproofing construction methods.
