The XPS board has a dense surface layer and a closed-cell structure inner layer. Its thermal conductivity is much lower than EPS of the same thickness, so it has better thermal insulation performance than EPS.
For the same building exterior wall, its thickness can be smaller than other types of insulation materials; due to the closed-cell structure of the inner layer. Therefore, it has good moisture resistance and can still maintain good thermal insulation performance in a humid environment; it is suitable for buildings with special requirements for thermal insulation such as cold storage, and can also be used for buildings with brick or stone exterior wall facing materials ；
Light texture and easy to use: The completely closed-cell foaming chemical structure of XPS board and its honeycomb physical structure make it light and high-strength, easy to cut and transport, not easy to break, and easy to install. Because the extruded polystyrene and the base wall are fixed by mechanical fixing parts. Construction can be done as usual in winter;
Good stability and corrosion resistance: In long-term use, it will not age, decompose, or produce harmful substances. Its chemical properties are extremely stable, and will not be degraded due to water absorption and corrosion, and its performance will be reduced. It can maintain its superior performance. According to relevant information, XPS extruded insulation board can maintain excellent performance even after 30-40 years of use, without decomposition or mildew, and no toxic substances volatilized.
