extruded xps foam board has high closed pore rate, good high thermal resistance, low thermal conductivity, low expansion ratio, thermal insulation and impermeability, which can reduce the circulation of air and loss of heat. therefore, laying extruded plastic panels with corresponding specifications and flame retardant level in the wall layer of the building can play a good thermal insulation effect.
extruded plastic board is a closed cell structure, both compressive strength and thermal conductivity system is better than polystyrene board, the thermal conductivity of the extruded plastic board is less than or equal to 0.03, while the benzene board is less than or equal to 0.041, from this point of view can also be seen in the same thickness of extrusion board itself in the thermal insulation effect of the superiority of extrusion board, therefore, to do the roof, the underground house and runway and other heat preservation, usually using extruded plastic board. extruded plastic board is currently used more in the thermal insulation system, has the advantages of good thermal insulation effect, easy construction. comprehensively speaking, extruded plastic board is suitable for roof insulation (high compressive strength), internal insulation of external walls (thin thickness, does not occupy the indoor area).
