Long-term use in Qingyun extruded sheet, not aging, decomposition, no harmful substances, the chemical properties of extremely stable and will not cause corrosion due to water absorption and degradation to performance degradation at high temperatures can still maintain its superior performance, according to the information, XPS extruded insulation board even with 30 to 40 years, can still maintain excellent performance extruded sheet, and decomposition or moldy leling extruded sheet will not happen, no toxic substances volatilization. For heat insulation is concerned, the key is how the thermal inertia index D, D coefficient is proportional to the value of the accumulator. But on the whole system, regenerative 200mm of concrete has been big enough, plus external insulation, fully meet the energy requirements. It is also integrated with national regulatory requirements of the wall thermal conductivity and heat storage coefficient of reasons to be satisfied. EPS or XPS thin plaster systems fully meet the requirements.
