1, expanded polystyrene board This is the most widely used external wall thermal insulation material, and thin plastering system, thermal insulation and decoration integrated system, large mold built-in system and so on are all frequently used. This material occupies a large proportion in the domestic and international thermal insulation system market. Undeniably, it is the most mature product used in external wall insulation system, so that all newly born materials will use this as a reference to PK to set off the good of each family.

2. At present, it seems that only the domestic market uses extruded polystyrene board as external wall insulation material. It can be said that extruded polystyrene board also integrates waterproof and thermal insulation functions, with high rigidity, good compression resistance and low thermal conductivity, which is very suitable for covering the roof, ground and basement wall for thermal insulation.

3. Thermal Insulation Mortar Thermal insulation mortar is a ready-mixed dry powder mortar made of various lightweight materials as the main material of external wall thermal insulation materials, cement as the cementing material, supplemented by some modified additives. Mainly used for building external wall insulation, with the advantages of convenient construction and good durability.

4. Phenolic foam Phenolic foam is internationally recognized as the most promising new external wall insulation material in the ranks of buildings. Because this new material is essentially different from the material obtained by adding flame retardant to ordinary polymer resin, it will not burn, melt or emit toxic smoke in fire, and has the advantages of light weight, non-toxicity, non-corrosion, heat preservation, energy saving, sound insulation and low price.

The function of external wall insulation

1, some people don't understand the function of external wall insulation materials and think it doesn't matter whether they do it or not. Actually, this is not right. The external wall thermal insulation material not only protects the main structure, but also prevents the major temperature change of the main structure, effectively improves the durability of the main structure and prolongs the service life of the building.

2. Exterior wall thermal insulation materials can not only improve the indoor environment, but also play the role of thermal insulation. In addition, it can also reduce the invasion of wind, rain and moisture, increase indoor dryness and avoid indoor humidity and mildew.

3. Installing thermal insulation materials on the exterior wall of the building not only responds to the national slogan of low carbon and environmental protection, but also alleviates the influence of cold and hot weather on the building and prolongs the service life of the building.
