1.Increase the Sd value of the entire insulation system（Sd≤2.0m）,the surface layer Sd ≤0.25m,Keep the wall dry for the entire service period.

2.Improve the key layer materials of the external insulation system, enhance the alkali resistance and fracture strength, and ensure long-term durability meets the design life requirements.

3.Improve the impact resistance of plaster and coating, ensure long-term flexibility, anti-cracking and other mechanical properties, improve durability.
