Thermal insulation because the thermal conductivity of foaming agent used in polyurethane is much lower than that of air (good thermal insulation performance), the thermal insulation performance of rigid polyurethane foam is better than those materials only containing air, such as mineral wool, glass fiber and polystyrene. Moreover, its unique closed cell property and high resistance to gas diffusion make it have superior long-term insulation performance, and its thermal insulation performance can last for 20-50 years or more.

The closed cell structure and surface material of the corrosion-resistant polyurethane rigid foam make it have better air and water vapor resistance, and it can be made into inlaid connection structure when forming, so it is easy to be assembled. It does not need additional insulation layer to prevent moisture, and saves a lot of trouble of laying insulation layer. These properties are not available to other insulating materials at the same time.

wide width, light weight and thin wall, as rigid polyurethane foam acts as structural material at the same time, makes the whole structure have the advantages of light weight, large span and high load. Compared with other insulating materials, rigid polyurethane foam has better thermal insulation properties. Therefore, the thinner polyurethane sandwich panel can meet the relevant provisions of the building energy consumption limit, which allows the use of thinner panels in construction and saves building space.

Nowadays, with the rapid increase of demand, the factory production line of polyurethane sandwich panel is not only convenient for quality control, but also brings good economy and competitiveness.

Good weather resistance, easy to install, polyurethane sandwich board prefabricated in the factory, can be directly used for construction and installation, without additional processes, construction is fast. And it doesn't need to take into account the change of the weather, and it can be produced according to the plan.
