Insulation materials for wall insulation are the most important inorganic green energy-saving and heat-insulating materials. In the energy-saving work of buildings, energy-saving is the theme, and fire protection is the key. In addition, there are engineering quality elements and green construction elements. Therefore, while attaching importance to fire prevention work, we must also consider compatibility with other elements.

The specific goal of the fire prevention work in the process of using insulation materials clearly For specific energy conservation projects, two types of fires must be prevented: one is the fire that occurs during the construction of energy-saving projects, and the other is the fire that occurs during the use of energy-saving projects. The fireproof finger during the construction of inorganic insulation board ensures that the external insulation material of the building is not easily ignited by other fire sources (such as sparks produced by cutting, welding, etc.); the fire protection in the process of use means that the external insulation system of the building is subject to external fire. During the attack, the inorganic insulation material will not spread and cause a large fire.

Therefore, the specific goal of fire prevention work should not be ignited or spread. â€œThe Notice of the Ministry of Public Security of the People's Republic of China on Further clarifying the requirements concerning the fire supervision and management of external thermal insulation materials for civil buildingsâ€ stipulates that external insulation systems for buildings can only use Class A flame-retardant materials, neither necessary nor practical. As long as we improve the technical level and enhance the flame retardancy of organic materials, we can achieve the goal of not igniting or spreading.

Inorganic green energy-saving insulation materials have considerable investment value. It can be seen that achieving the energy-saving goal of the wall is the premise of all work. The inorganic insulation board promotion building exterior wall insulation technology and fire prevention measures cannot be at the cost of reducing energy-saving efficiency. The specific objectives of the fire prevention work should be determined and the flame retardancy of the exterior thermal insulation materials of the external walls of the building should be constantly enhanced.

The external fire protection policy has opened up a new era for inorganic insulation materials. The so-called A-grade refers to non-combustible materials. However, the popular building insulation materials in China today are mainly organic materials. Even if flame retardants are added, they can only reach Class B1. If we strictly enforce the most stringent fire order in this history, it means that China's thermal insulation materials industry will face the situation of reshuffle across the board or even eliminated. The inorganic insulation materials such as empty glass beads, expanded perlite, closed-cell perlite, rock wool, and foamed concrete have a natural fireproof advantage. The introduction of this policy undoubtedly opens up new materials for exterior wall insulation board materials. era.
