The first uppermost coating layer of heat insulation and damp-proof roof system is designed as a protective topcoat roofing system that is resistant to UV radiation. The second damp-proof layer is applied under the first coat of paint, is made as sprayed damp-proof membrane, which can be applied on concrete, polyurethane, polystyrene, fabric, bituminous and other roof insulation layer. It can also be used for various single layer damp-proof sealants. The third layer of heat insulation applied on base and under the damp-proof layer is a two-component polyurethane hard foam with closed cell structure, which foams up after spraying in situ. It is intended for making cavitiesless heat insulation structures in building construction, civil engineering and underground construction. |
