Extruded Polystyrene Heat Insulation Board Good Thermal Insulation Insulation
Aug 01, 2018

With the characteristics of high thermal resistance, low linearity and low expansion ratio, the closed hole rate of its structure reaches more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, ensuring the durability and stability of its thermal insulation performance. Compared with the closed hole rate of 80% of foamed polyurethane, its leading edge is self-evident. It has been proved in practice that the thermal insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite. Therefore, this material is the best choice for building insulation at present.
