External wall insulation is a method of putting the insulation layer outside the main wall material, which is equivalent to adding protective materials to the entire building, which is the most recommended. So what are the advantages of external wall insulation?

1. Energy saving and good effect

Since the thermal insulation material is placed on the outer wall of the building, it can basically eliminate the influence of cold and thermal bridges in various parts of the building; it can give full play to the thermal insulation performance, and when the same thermal insulation material is used, the thickness of the thermal insulation material is required to be smaller and more energy-saving.

2. Improve the indoor environment

The external thermal insulation improves the thermal insulation performance of the wall and increases the indoor thermal stability. It also prevents wind, frost, rain, snow, etc. from soaking the outer wall to a certain extent, improves the moisture resistance of the wall, and avoids indoor mildew, condensation, and cold. Because the insulation material is laid on the outside of the wall, the pollution of the indoor environment by the volatile harmful substances in the insulation material is avoided.

3. Extend the service life

The insulation layer placed on the outside of the building greatly reduces the influence of natural temperature, humidity, ultraviolet rays, etc. on the main structure, protects the main structure and prolongs the life of the building. Due to the influence of temperature on the structure, the thermal expansion and contraction of the building’s periphery may cause the cracking of some non-structural components of the building. The use of external thermal insulation technology on the outer wall can reduce the stress generated by the temperature inside the structure.

4. Wide range of applications

The external insulation of building exterior walls is not only suitable for buildings that require heating in winter, but also for air-conditioned buildings that require heat insulation in summer. It is not only suitable for the thermal insulation of the external wall of the brick-concrete building, but also the thermal insulation of the concrete external wall of the shear wall structure. It is suitable for both new houses and old house renovation.

However, if a fire occurs, the external wall insulation cannot protect the building from burning.
