Since there have been frequent fires in various places, causing heavy losses of property, fire is something that no one wants to see, and in terms of external wall insulation, one cannot ignore the other. When using rock wool insulation board, it is necessary to ensure the thermal insulation effect and at the same time pay attention to whether the fireproof performance meets the standard. In addition, it must also help save energy while preventing fire. But ignore the important principle of energy saving.

Inorganic thermal insulation materials are represented by rock wool, foam glass and foamed cement. The thermal conductivity of rock wool and slag wool is usually between 0.036 and 0.041W/(m·K) at room temperature (about 25°C). It is an inorganic silicate fiber and is non-flammable. Rock wool has the characteristics of fire prevention, thermal insulation, etc. It is specially designed and produced for the external thermal insulation thin plastering system of the external wall of the building. It is suitable for the external walls of new or existing buildings with dense structures such as concrete or brick walls It can also be used as a thermal insulation and fire isolation belt for external walls, and it can be used in conjunction with thermal insulation materials whose combustion performance cannot reach to improve the fire protection function of external walls of buildings.

External wall insulation should combine the four disciplines of building science, material science, fire science and environmental protection science. Any research that deviates from the four major disciplines is relatively one-sided and limited. To do a good job of fire protection of external wall insulation, you need to do the following:

1) Strictly implement various fire regulations and fire protection systems;

2) Choose a good thermal insulation material;

3) Do a good job of fire prevention measures in the initial stage of the use of thermal insulation materials;

4) Monitor the construction process in the intermediate stage of the use of thermal insulation materials to prevent the possibility of various fires;

5) After the thermal insulation material is made into an external wall thermal insulation system, the thermal insulation system should be properly used and the occurrence of fire should be prevented.

The fire prevention problem of external wall insulation should be integrated with various factors. It is not only possible to rely on the fire resistance of thermal insulation materials such as external wall insulation boards to prevent the occurrence of fires. It is necessary to comprehensively manage and prevent fires, and to choose a special construction team!
