Due to the advantages of the above series of exterior wall insulation technologies and the favorable conditions for using heavy materials in the main body of the exterior wall, on the basis of learning to introduce various exterior wall insulation systems, insulation technology has developed rapidly in recent years, and some high-quality and unique exterior wall insulation buildings have been built in many cities.

Exterior wall insulation materials, also known as sky building exterior insulation decorative integrated panels. Made of polymer mortar, fiberglass mesh, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS). The product has reached Class A non-combustibility, has the characteristics of low thermal conductivity, fire resistance, waterproof, light weight, high strength, etc., and is an alternative to various insulation materials. Its thermal conductivity is very low, and its fire resistance is better than that of ordinary polystyrene boards. The only disadvantage is that the price is slightly higher.

Exterior wall insulation materials can collect excess heat and release heat stably and timely with a small gradient change, and effectively reduce losses. The trend of room temperature and insulation in winter can play a balancing role. When the decoration of new buildings and old buildings use raw materials such as floating beads, brucite fibers (tubular fibers), a closed hydrophobic microporous structure is formed in the structure. As a carrier of phase change materials, the long-term practicality of phase change materials can be guaranteed. .

At the same time, the exterior wall insulation material has excellent sound insulation and shock absorption properties, and is an indispensable high-efficiency insulation material in the fields of metallurgy, chemical industry, national defense, and aerospace.
