How many grades are China's current standard insulation materials divided into? How effective is the insulation material like extruded board?

Class A (non-combustible), Class B1 (flame retardant), Class B2 (flammable) and Class B3 (flammable) are now generally used in the market to require Class A, and the internal insulation of external walls is at least Class B1.

XPS thermal insulation board is an extruded polystyrene thermal insulation board, which is made of polystyrene resin as raw material plus other raw materials and poly inclusions. It is heated and mixed while injecting catalysts, and then extruded and molded. The rigid foam plastic board. Its scientific name is extruded polystyrene foam (XPS) for heat insulation. XPS has a perfect closed-cell honeycomb structure. This structure allows XPS board to have extremely low water absorption (almost no Water absorption), low thermal conductivity, high compression resistance, aging resistance (almost no aging decomposition phenomenon in normal use).

Advantages of XPS board exterior wall insulation system:

High-strength compression, water-repellent, moisture-proof, light texture, convenient use, stability, good corrosion resistance, product environmental protection

It is suitable for building roof insulation, steel structure roofing, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air-conditioning ventilation ducts, airport runway insulation, high-speed railway subgrades, etc.
