Fire-proof rock wool board and thermal insulation rock wool board are essentially rock wool board products, and both are made of natural rocks as the main raw materials, but there are some significant differences in performance, manufacturing technology, structure and application.

The main function of fireproof rock wool board is fire prevention and flame retardant. This kind of rock wool board is made of high-quality basalt rock as the main raw material and processed by high-temperature melting and high-speed centrifugation, which has high fire resistance limit and melting point. It can keep burning for a long time at high temperature, and does not produce toxic gas and molten droplets. This enables the fireproof rock wool board to form a fire barrier in the building system, effectively prevent the spread of fire, buy time for fire rescue and escape, and thus reduce property losses and casualties caused by fire.
