Is rock wool fireproof？

With the continuous improvement of building fire prevention requirements, rock wool has gradually become an important choice for modern building materials due to its superior fire resistance, environmental properties, and wide application. Rock wool is an inorganic fiber material made by melting natural rocks at high temperatures.

1. Excellent fire resistance: preventing the spread of fire

Rock wool material has excellent high temperature resistance due to its melting of natural minerals such as basalt and kaolin. Usually, the melting point of rock wool is over 1000 ℃, which can effectively prevent the spread of flames in the event of a fire. Its unique inorganic fiber structure not only does not burn, but also absorbs the heat of flames, buying valuable rescue time for building structures. Rock wool is widely used as a fireproof isolation layer for walls, ceilings, and pipelines, becoming one of the preferred materials for building fire prevention.

2. Thermal insulation: dual safety and energy-saving benefits

In addition to fire prevention, rock wool also has excellent thermal insulation properties, with a thermal conductivity as low as 0.038W/(m · K). (https://www.alibaba.com/)This characteristic enables rock wool to reduce heat loss and maintain temperature stability inside the building. Especially in winter and summer, using rock wool can significantly reduce the energy consumption of air conditioning and heating, achieving energy-saving effects. This dual function makes rock wool not only perform well in the field of fire prevention, but also bring higher energy efficiency to buildings.

3. Environmental characteristics: Fire resistance real testing
According to the video and online activity, the rock wool insulation board and rock wool insulation roll produced by Hebei Lanxuan(https://www.hb-lanxuan.com/) Company have Class A non combustion when burned with a spray gun. After about 5 minutes of burning with the spray gun, when the rock wool melts, there is no open flame phenomenon
