Rock wool is an inorganic thermal insulation material, which is made of basalt as the main raw material, melted at high temperature, made into artificial inorganic fibers by high-speed centrifugal equipment, and then processed. It has the advantages of light weight, low thermal conductivity, heat absorption, incombustibility and fire prevention. The main raw material for producing rock wool is basalt, which is an inorganic fiber material, non-flammable and fire-resistant, and can withstand high temperature, which is higher than that of glass wool. The high energy resistance of glass wool can reach about 300 to 400 degrees, while that of rock wool can reach about 1000 degrees.
Because the main raw material of rock wool is basalt, which has strong compression resistance and weather resistance, this is an important performance advantage of rock wool. In addition, according to the different shapes and systems of rock wool, rock wool products and systems are mainly divided into rock wool insulation board, rock wool tube, roof insulation system, curtain wall fire insulation system and external wall insulation system, all of which have thermal insulation performance, fire prevention performance, excellent durability and hydrophobicity.
