Performance features:
1. Thermal insulation
With the characteristics of high thermal resistance, low linearity and low expansion ratio, its structure has a closed-hole ratio of more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the durability and stability of its thermal insulation performance. Compared with the 80% closed-hole ratio of foaming polyurethane, its leading advantage is really obvious. Practice has proved that 20mm thick XPS extrusion insulation board, its insulation effect is equivalent to 50mm thick foam polystyrene, 120mm thick cement perlite. Therefore, this material is the best choice for building heat insulation.
