北京赛车PK10计划  Extruded polystyrene board is a kind of thermal insulation material often used in the process of construction now. As the saying goes, no one is perfect. So is the insulation material of extruded polystyrene board. The manufacturer of extruded polystyrene board reminds you that the extruded polystyrene board has many advantages and disadvantages.

When concentrated force occurs on the plate, it is easy to damage and crack; the air permeability of extruded plate is relatively poor, if the temperature difference between the two sides of the plate is large, condensation will occur; and the expansion is also poor, and it is easy to bulge, deform and even fall off in the environment with large temperature change The price is higher than that of EPS system because it has not been issued national standard for a short time.

This structure also makes the extruded panel have good moisture resistance. Even in humid environment, it can also achieve excellent thermal insulation performance, which has a wide range of applications in building thermal insulation.
