Polystyrene board is used as insulation layer、 which is called polystyrene foam board、 also known as foam board or EPS board. It is a white solid with a fine closed cell structure formed by heating and pre releasing expandable polystyrene beads containing volatile liquid foaming agents in a mold. Compared with extruded polystyrene board (XPS board)、 expanded polystyrene board (EPS board) has a higher water absorption rate and is prone to water absorption、 which is a disadvantage of this material. The water absorption rate of its insulation board has a significant impact on its thermal conductivity. As the water absorption rate increases、 its thermal conductivity also increases、 and the insulation effect also deteriorates. Therefore、 special attention should be paid to this point p>
