Inorganic green energy-saving thermal insulation material is the first choice for wall thermal insulation materials

In the building energy conservation work, energy conservation is the theme, and fire prevention is the key. In addition, there are engineering quality elements and green construction elements. Therefore, while paying attention to the fire prevention work, we should also consider the compatibility with other elements.

Clear the specific objectives of fire prevention in the process of using thermal insulation materials

For specific energy-saving projects, two kinds of fires should be prevented: one is the fire occurred in the construction process of energy-saving projects, the other is the fire occurred in the use of energy-saving projects. The fire prevention in the construction of inorganic thermal insulation board refers to ensuring that the external thermal insulation materials are not easily ignited by other fire sources (such as sparks generated by cutting, welding, etc.); the fire prevention in the use process refers to that when the external thermal insulation system is attacked by external fire sources, the inorganic thermal insulation materials will not spread to form a large fire.

Therefore, the specific goal of fire prevention should be no ignition and no spread. According to the notice of the Ministry of public security of the people's Republic of China on further defining the relevant requirements for fire protection supervision and management of external thermal insulation materials for civil buildings, it is unnecessary and not in line with the actual situation that only grade a flame retardant materials can be used in the external thermal insulation system of buildings. As long as the technical level is improved and the flame retardancy of organic materials is enhanced, the goal of no ignition and no spread can be achieved.

Inorganic green energy-saving thermal insulation materials are worth investment

It can be seen that the realization of wall energy-saving goal is the premise of all work. The promotion of building external wall insulation technology with inorganic thermal insulation board and the adoption of fire prevention measures can not be at the cost of reducing energy-saving efficiency. The specific target of fire prevention should be determined to enhance the fire resistance of external thermal insulation materials.

Fire prevention policy of exterior wall opens up a new era for inorganic thermal insulation materials

The so-called "a" refers to non combustible materials, but at present, the most popular building external insulation materials in China are organic materials. Even if flame retardant is added, the maximum can only reach B1 level. If we want to strictly implement the most stringent fire protection order in history, it means that China's thermal insulation material industry will face the situation of reshuffle and even elimination. The inorganic thermal insulation materials such as hollow vitrified beads, expanded perlite, closed cell perlite, rock wool, foamed concrete and other materials have natural fire protection advantages. The introduction of this policy will undoubtedly open up a new era for thermal insulation board materials without external wall machine.
