Advantages of extruded insulation board XPS: XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the EPS same thickness, so it has a better than the EPS insulation properties. For the same building facades, its thickness can be less than other types of insulation materials; the closed cell structure of the inner layer. So it has good moisture resistance in humid environment can still maintain good thermal insulation properties; suitable for cold storage and other special requirements for building insulation, can also be used for exterior finish materials as brick or stone buildings ; light texture, easy to use: the chemical structure is completely closed-cell foam XPS physical structure of honeycomb panels, it has a light weight, high strength characteristics of one stone plate processing, easy to cut, transport, and unbreakable, easy to install. Because fixation extruded polystyrene wall with grass to the use of mechanical fasteners. As usual construction in the winter; stability, corrosion resistance: long-term use of thin stone one board processing, aging, does not decompose, does not produce harmful substances stone one board, its chemical properties of extremely stable, not because of absorption and as a result of corrosion degradation to performance degradation at high temperatures can still maintain its superior performance, according to the information on one plate stone wholesale, XPS extruded insulation board, even 30 to 40 years, can still maintain excellent performance, and will not decompose or mildew, no volatile toxic substances.
