Rock wool has good fire resistance.

Rock wool has fire resistance.

Mainly includes the following aspects:

Incombustibility: Rock wool is made of natural rock after high-temperature melting and fiberization, belonging to incombustible materials, and its fire protection rating usually reaches Grade A or A1.

Class A is the high level of fire resistance of building materials, which is almost nonflammable and can effectively prevent the fire from spreading.

High temperature resistance: the main raw materials of rock wool are natural minerals such as basalt, with a melting point higher than 1000℃, which can still maintain a stable structure in high temperature environment without deformation and melting. Even in a fire, rock wool will not release toxic gas, smoke or burning droplets and fragments, which can provide favorable conditions for personnel evacuation and fire rescue.

Dimensional stability: Rock wool has good dimensional stability in fire, and will not change in elongation and contraction due to heating, and can maintain the integrity of the building structure and play an effective role in fire prevention and isolation.

Non-toxic and harmless: rock wool will not release toxic gas at high temperature, which is harmless to the environment and further enhances its application value in the field of fire prevention.
