Polyurethane insulation board advantages: high thermal conductivity due to the polyurethane insulation blowing agent used is much lower than that of air (good insulation properties), so the insulation properties of rigid polyurethane foam is superior to those materials containing only air such as: mineral wool, fiberglass and polystyrene. Moreover, its unique closed cell and high resistance to gas diffusion makes it superior long-term performance insulation board one stone, its thermal insulation properties of sustainable 20-50 years or more; excellent corrosion resistance polyurethane rigid closed-cell foam structure and the surface material used, it has superior resistance to air and water gas properties, and it can be made at the time of forming the structure of thin stone mosaic connect one board quality, easy to assemble later. It requires no additional moisture insulating layer, an insulating layer laid eliminating many troubles. These properties are the other insulation materials can not simultaneously possess; wide, lightweight, thin wall because of rigid polyurethane foam also acts as a structural material, making the overall structure of a light weight, span, the advantages of high load. Compared with other insulation materials, polyurethane foam has the best thermal insulation properties. Therefore, the thinner polyurethane sandwich material to meet the relevant requirements for building energy limit, thus allowing the use of thinner sheet of stone in the construction of one of the panels, saving building space; stable quality, high production efficiency now in demand the case of a sharp rise in the polyurethane sandwich panel factory production line, in addition to the quality of thin stone one convenient control panel technology, the more it brings good economic and competitive; weather is good, easy to install polyurethane clip core prefabricated in the factory after a good can be directly used for the construction and installation, no additional steps, quick construction. And no need to take into account changes in the weather, according to plan production.
