Class A fireproof material is a fireproof material used in high-rise buildings.
With the frequent fire accidents caused by external insulation fires in high-rise buildings, and the gradual improvement of national building energy-saving standards from 65% to 75% energy saving, it is inevitable that the external wall insulation system needs to choose Class A fireproof insulation materials. trend!
National Class A fireproof flexible materials are composed of inorganic powders such as soil, stone powder, sand, cement waste blocks and modifiers. The product density is 2327kg/m3. After inspection, the combustion performance of this product meets the requirements of Class A. Requirements, additional classification should comply with the requirements of s2, d0, t0 levels. According to GB8624-2006, the combustion performance of this product reaches A2-s2, d0, t0 level.
Extended information
1. Class A fireproof and thermal insulation board has good stability
The components of similar and fused Class A fireproof and thermal insulation board are through bonding, mechanical The structural components are relatively similar or close to each other through chemical or physical means. Therefore, system stability can be guaranteed even in harsh environments such as temperature changes, sunshine, rain, frost, severe cold, high temperatures, acid and alkali, etc.
The scientific and unique internal structure of the Class A fireproof insulation board is in harmony with the microscopic movement of the main body of the building. Supporting materials, special-shaped components and supporting tools for Class A fireproof insulation board systems.
Completed the system design of the entire system and applied core technologies such as cavity-free technology, breathing technology, and waterproof technology, so that the entire system can maintain harmony with the microscopic movement of the main body of the building through scientific internal system adjustments** * place.
2. Class A fireproof insulation board has breathing function and no negative pressure.
The unique breathing technology of Class A fireproof insulation board can prevent internal moisture on the premise of eliminating negative pressure. The accumulation of heat, as well as the shortcomings caused by the alternation of high and low temperature changes, avoid the safety hazards of Class A fireproof insulation boards.
3. Class A fireproof insulation board reduces the difficulty of construction and shortens the construction period
Class A fireproof insulation board has very good thermal insulation performance, coupled with the patented anchoring method, node and cold bridge design The treatment reduces energy-saving losses. Therefore, especially in areas with harsh climates such as the Northeast and Northwest, the requirements for energy-saving and thermal insulation are often very high, and traditional thermal insulation construction brings great difficulty to the construction.
4. Class A fireproof insulation board is lightweight and high in strength
The fully automated production in the dust-free workshop of the factory and the standardized and meticulous operations ensure that the entire production process is dust-free. ization, avoiding the instability of quality caused by previous discrete technologies.
