The difference between extruded board, polystyrene board and extruded polystyrene foam board
4 rubber powder polyphenyl particle insulation slurry, thermal conductivity 0.057-0.06, good flame retardancy, waste recovery, insulation effect is not ideal, high construction requirements.5 polyurethane foam material, thermal conductivity of 0.018-0.024, good waterproof, good insulation effect, high strength, more expensive.6 perlite and other slurry, thermal conductivity 0.06-0.08, good fire resistance, high temperature resistance, poor insulation effect, high water absorption.
Rock wool board 0.041-0.045 thermal conductivity, fire retardant, moisture absorption, insulation effect is poor.
1 expansion polystyrene board (EPS board) thermal conductivity 0.038-0.041, good insulation effect, cheap price, poor strength.2 extruded polystyrene board (XPS board) thermal conductivity 0.028-0.03, better insulation effect, high strength, moisture resistance, expensive, the surface of the construction needs to be dealt with.
