Stone wool board, also known as rock wool insulation decorative board, is an inorganic fiber board mainly made of basalt and processed by high-temperature melting. It was successfully tested in June 1981 and is a new type of insulation, flame-retardant, and sound-absorbing material. Rock wool board is an artificial inorganic fiber processed by high-temperature melting, which has the characteristics of light weight, low thermal conductivity, heat absorption, and non flammability. Its initial development is a common application type in construction, mainly used in industrial buildings, and should comply with the provisions of the "Application Types and Basic Requirements of Building Insulation Materials".
