11.Rock wool fiber insulation material is a kind of insulation material made of basalt rock fiber. It is known for its high efficiency in improving the energy efficiency of buildings and industries. The insulation is made by melting basalt rock and then spinning it into fibers, which are then compressed into rigid plates or cotton wool. This process resulted in a durable fireproof material with excellent thermal and sound insulation properties. Rockwool insulation materials are commonly used in commercial and industrial buildings, industrial thermal insulation, and residential. It is also effective in soundproofing applications, as it can significantly reduce the propagation of noise.
