Why build a house with plastic foam?
The foam board used for exterior wall insulation is called polystyrene foam board.Polystyrene foam board, foam board, also known as the EPS board is composed of expandable polystyrene beads containing a volatile liquid foaming agent, the white object heating molding in the pre heating, the structure characteristics of the tiny, mainly used for building wall, roof insulation, composite insulation board, cold storage, air conditioning, vehicles, ship insulation, floor heating, decoration carving is widely used.
You say plastic foam is used for building exterior wall insulation, is a kind of external wall insulation material.A variety of traditional wall insulation, external insulation, is made from polymer mortar, glass fiber mesh cloth, flame retardant molded polystyrene foam board (EPS) or extruded plate (XPS) etc. composite materials, bonded construction site. New type of insulation decorative integration is through the production line, set insulation, waterproofing and decorative functions, is to meet the current demand of building energy saving, improve the material of industrial and civil building exterior insulation level, but also on the first material material of energy-saving renovation of existing building.
The effect of polystyrene foam board:1. protect the main structure of the building and prolong the life of the building. Because the exterior insulation is to place the insulation layer outside the structure, it reduces the pressure caused by the structural deformation caused by the change of temperature, and reduces the erosion of the harmful substances and ultraviolet rays in the air.2. eliminate the "bridge" used in the insulation, the thermal bridge is difficult to avoid, and effectively prevent the thermal insulation production, avoid condensation.3. the wall moist situation improved, the general need to set up internal insulation vapor barrier layer, through the performance of temperature and the external insulation insulation material is much stronger than the main structure, inside the wall is generally not condensation phenomenon, the wall temperature of structure layer was increased to further enhance the wall insulation performance.4., to maintain stability at room temperature, the use of external insulation wall, because the wall heat storage capacity of the larger structure layer in the wall inside, conducive to room temperature to maintain stability.5., increase the use of housing area. Can avoid the two decoration damage to the insulation layer.
