Advantages of XPS: XPS board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the same thickness of EPS, EPS and therefore has relatively better thermal insulation properties. For the same building facades, its thickness can be less than other types of insulation material; the inner layer of closed-cell structure. So it has good moisture resistance, xps extrusion board b1, in a humid environment can still maintain good thermal insulation properties; suitable for cold storage and other special requirements for insulation building materials can also be used for external walls as brick or stone buildings; 3), the combustion performance is poor, xps extrusion board 30mm, EPS material cause it has been in an abnormal level, fire xps extrusion board, Radio Beijing is very low because the combustion performance leads to EPS a. Insulation board said straightaway that to building heat preservation board. Insulation board is a polystyrene resin as raw material, together with other raw materials and polymer-containing material, plastic sheeting, with moisture, water resistance, can reduce the thickness of the external structure of buildings, thereby increasing the indoor area. Features insulation board: high fire resistance, high heat resistance, strength is relatively good, not broken, light weight, non-toxic, long life, good water resistance, good interface, energy security.
