Longsheng closed cell foam board density 
 High-density polyethylene closed cell foam panels use method polystyrene foam board - also known as foam board, EPS board containing the volatile liquid blowing agent can be made of polystyrene beads by heating advance in the mold heating the molding white object, has a fine closed-cell structure characteristics, mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration engraving uses a very extensive. 
 Second, the insulation has the following advantages: 
 One of the main building structure to protect and extend the building life. The outer insulation is the insulation layer in the structure of the lateral, lower stress due to temperature changes caused by structural deformation, and to reduce harmful substances in the air and ultraviolet light on the structural erosion. 
 (2) the effective elimination of the "thermal bridges" In the past, insulation, thermal bridges are hard to avoid, while the external wall insulation to prevent heat bridge, to avoid condensation. 
 . Wall influx of warm situation to improve, generally within the insulation required vapor barrier, exterior insulation insulation materials through the temperature performance is much stronger than the main structure generally does not occur within the wall condensation, structural layer The entire walls of the temperature increased to further enhance the wall insulation performance. 
 (4) stable at room temperature, the use of exterior insulation and finish the inside due to the large heat storage capacity of the wall structure layer in the wall, the room temperature He held stable. 
 (5) increase the use of housing area. To avoid re-decoration, the destruction of the insulation layer.
