XPS insulation board is extruded polystyrene insulation material with high density. It has smooth surface through extrusion, and has completely closed cell inside. This kind of material has excellent heat insulate performance, high moisture resistance, lightweight, excellent compressive strengths, and anticorrosion. This is ideally use for the construction industry.
XPS insulation board has 99%closed cell rate. As a result for high heat resistance, low expand rate and low thermo conductivity. The heat insulation effect of 25mm thick XPS board is superior than 120mm thick concrete perlite. It is usually used in apartments, high-rise buildings, workshop, cold storage warehouse etc for heat insulation.
