Dimensional stability. Industry Rideau think extruded sheet for exterior insulation due to poor dimensional stability, due to the effects of climate which led to its size deformation, resulting in cracking paint finish layer, as the EPS system. In fact, we can from the elastic modulus of the system in terms of the three materials, mortar about 15500MPa, EPS is about 4 ~ 6MPa, XPS is about 7 to 9MPa general board and the biggest difference is that there is no fire-retardant board added resistance flame retardants, slightly lighter weight: 32 kg retardant board each side above, only about 28-31 kg P board. "The cost price is high flame retardant board is therefore also increased significantly." The general board did not add flame retardant effect is not good, or even fire rate is zero. This board is relatively cheap price, 340 yuan per cubic meter; a variety of specifications, 2 cm to 10 cm, and other models, the price is not the same. Retardant board points B1, B2 grade insulation board, see GB8624-1997 (old standard) B2 grade insulation board, fire board production technology for high fire-retardant insulation board, good flame-retardant effect, can effectively guarantee the safety of construction insulation board 60mm, reduce project risks and losses, and therefore, the Ministry of Construction and the Ministry of Public Security jointly issued No. 46 prohibits non-flame retardant wall panel, because the project cost will increase, many construction side desperate, which makes the project very serious security problem .
