Pu sandwich board is a polyurethane insulation sandwich board for building, also known as leakproof sandwich roof panel, polyurethane sandwich board, polyurethane rigid foam insulation board, polyurethane composite board and so on. Polyurethane sandwich panels are produced by advanced continuous production line of sandwich panels, which are formed by cold bending of internal and external galvanized (aluminized and galvanized) coloured steel sheets and hard polyurethane foams coated in the middle. It is a widely used and potential energy-saving building envelope material. It is also a new energy-saving plate advocated and promoted by the Ministry of National Construction.
Pu sandwich board composite plate has small thermal conductivity and good thermal insulation performance, so it is a good thermal insulation material. Beautiful shape, convenient installation, good fire protection, non-toxic and tasteless, green environmental protection, wide use temperature range, it integrates load-bearing, heat preservation, fire prevention and waterproofing, and does not need secondary decoration, quick and convenient installation, short construction period, good comprehensive benefit, good cost-effective, is a widely used, highly potential energy-saving building envelope material, is also a country. A new type of energy-saving plate advocated and promoted by the Ministry of Construction.
The Pu sandwich board is connected by hidden nails, and the surface of the board is lapped tightly. Unique waterproof tank design can effectively prevent rainwater infiltration and avoid cold bridge phenomenon. The peak height of 40mm greatly improves the bearing capacity of roof slab. While ensuring the thermal insulation effect of the building, it can effectively reduce the construction cost of customers, and the roof slope can be as low as 3%.
There are no exposed screw on the surface and the building wall is graceful and smooth. Extremely high flexural capacity, superior wall mechanical properties, reduce the dependence on auxiliary steel structure. Excellent thermal insulation performance, reduce the cost of building indoor air conditioning equipment. Various appearance effects, beautiful wall.
