Rock wool products are made from natural mineral wool such as basalt and dolomite.
Rock wool products are made from natural mineral wool such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500℃. Rock wool reaches the highest fire-protection rating. Incombustibility and no release of toxic gas or smoke. Good performance in thermal insulation, and long-term satility, excellent air permeability and convenient construction. High resistance against shrinkage at high temperature, and stable structure even in fire. Efficient noise absorption and damping. Light weight, and easy cutting or sawing and other processing. Causing no corrosion to metal materials and other parts of building. Safe use due to non-toxicity of fiber.
Rock wool is mainly used in commercial, residential buildings and industrial plants, for application in roofing, external wall, partition wall and floating floor.
