In the notice, it is also recommended to promote the use of thermal insulation products with Class A and Class B1 combustion performance, such as rock wool composite panels, rock wool composite polyurethane fire-proof thermal insulation panels, vacuum thermal insulation panels, as well as graphite polystyrene panels (SEPS), molded polystyrene panels Sheet (EPS), Polyurethane Rigid Sheet (PIR), Polyurethane Rigid Foam (spraying on site), Graphite Extruded Plastic Sheet (SXPS), Extruded Polyurethane Sheet (XPS), etc. Restrict the use of cement or anchor bolts and external thermal insulation systems for thin plastered exterior walls combined at the construction site, and restrict the use of thermal insulation materials with a combustion performance of B2 level, as well as extruded plastic panels (XPS) for thermal insulation produced from recycled materials etc., to improve the fire resistance level of the insulation system.
In order to ensure the construction quality of the building thermal insulation project, when using the large formwork built-in cast-in-place concrete composite thermal insulation board system for the construction of the external wall of the building, the formwork should be set up. Before the insulation products enter the site, the product refractory and durability quality sampling test documents shall be provided. Before the composite insulation board leaves the factory, the manufacturer should do the layout design and processing according to the construction drawing and the actual size of the site, and spray the interface mortar coating according to the regulations. The cast-in-place concrete has a built-in thermal insulation system. The thermal insulation products should be typed and processed according to the requirements of the in-depth design before leaving the factory, and the interface should be sprayed and coated with mortar according to the regulations. Assembly, it is strictly forbidden to assemble semi-finished products on the construction site. The notice also requires that the sampling inspection of material quality will be increased, the quality supervision of the entire process of external wall insulation projects will be strengthened, and violations of mandatory standards for building energy conservation and fire protection, arbitrary reduction of standards, and cutting corners and other violations of laws and regulations will be seriously investigated and dealt with.
Jishang New Building Materials is a professional manufacturer of building thermal insulation materials. The rock wool thermal insulation panels and vacuum thermal insulation panels produced are famous for their high combustion performance (combustion performance reaches Class A) and strong thermal insulation performance. Compression resistance, corrosion resistance and long life.
