1. Excellent and durable thermal insulation
The lowest possible thermal conductivity is the goal pursued by all insulation materials. The extruded board is mainly made of polystyrene, which is originally a low thermal conductivity material, and then extruded with the help of extrusion, the tight honeycomb structure can prevent heat conduction more effectively, and the thermal conductivity of the energy-gathering board is 0.028W/m·k, with the characteristics of high thermal resistance and low linear expansion rate. The thermal conductivity is much lower than other insulation materials. Such as EPS board, foamed polyurethane, thermal insulation mortar, perlite, etc.
2. Superior water resistance and moisture resistance
The extruded board has a tight closed-cell structure, the polystyrene molecular structure itself does not absorb water, and there are no gaps on the front and back of the board, so the water absorption rate is extremely low, and it has moisture-proof and impervious properties.
3. Corrosion resistance and durability
Ordinary rigid foam insulation materials are prone to aging after several years of use, which will lead to water absorption and performance degradation. The extruded board has excellent anti-corrosion, anti-aging, heat preservation, and can still maintain its excellent performance under high water vapor pressure, and its service life can reach 30-40 years.
