XPS thermal insulation boards are made with polystyrene through special process which the hard expanded board is extruded. There is a sealed and foamed structure, which is an environmental protection material with the performances of high-resist compression, waterproof, moistureproof, air proof, light weight, anti-corrosion, long service life and low conductivity factor and so on..
