Advantages XPS system is that: 1), XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the same thickness of EPS, EPS and therefore has relatively better thermal insulation properties. For the same building facades, its thickness can be less than other types of insulation materials. 2), since the closed cell structure of the inner layer. So it has good moisture resistance, xps extrusion board density in a humid environment can still maintain good thermal insulation properties; suitable for cold storage and other special requirements for building insulation xps extrusion board, can also be used for exterior decorative material is brick or stone buildings. 3), XPS board has a good compressive strength xps extrusion board specifications in construction, easy to crack and damage, which attributed to the high compressive strength of XPS boards. Wide, light, thin wall due to the rigid polyurethane foam also acts as a structural material Henan xps extrusion board, making the overall structure is light weight, span, the advantages of high load. Moreover, its unique closed cell and high resistance to gas diffusion makes these have superior long-term insulation properties, its thermal insulation properties of sustainable 20 - 50 years or more.
