In accordance with national standards, extruded sheet name is called extruded polystyrene foam insulation, Zhangqiu retardant extruded board, insulation, Texas retardant extruded board, fire-retardant, compression, environmental protection and other effects are the most important function, the current national standard GB8624 "building materials products of combustion classification" provisions: B2 level is now the minimum requirement retardant XPS board oxygen index ≥26. According to "People's Republic of China Fire Act" Article 26 "building components, building materials and interior decoration, fire resistance decorative materials must comply with national standards; no national standards, must comply with the industry standard" requirement, extruded plate in the production process need to add flame retardants, Liaocheng retardant extruded plate to prevent and delay the intense burning polystyrene plates. Extruded sheet "See the fire that is burning," it shows that the body wrapped in the building of this layer "thermal coat" has become extremely dangerous. "Incendiary." Shanghai apartment fire teachers, Shenyang Dynasty Wanxin building blocks of ...... beautiful building into a black coke, countless lives were swallowed Huomo instant. And one of the causes of fires, because XPS board lost cause fire retardant properties wantonly spread. The XPS is just no such concerns. Further wind pressure resistance performance is weathering an important one, fire-retardant extruded board, because the system the more wind-resistant capability cavity worse. So the focus will depend on the size of the entire insulation system with the primary bond area. Also depends on the level of resistance to pressure test the typhoon and south winds comparison will be. The XPS system is better than the EPS system, which is determined by the performance of the plate itself. General life of the insulation system is 25 years, but then the existing insulation work abroad, the longest service life has reached 40 years. XPS insulation system can be effective for 50 years.
