stone wool board, also known as stone wool thermal insulation decorative board, is an inorganic fiberboard made of basalt as the main raw material and processed by high-temperature melting. In June 1981, the stone wool board was successfully tested as a new type of thermal insulation, flame-retardant and sound-absorbing material.

stone wool board is a kind of artificial inorganic fiber processed by high temperature melting, which has the characteristics of light weight, small thermal conductivity, heat absorption and non combustion. The initial development is a common application type in the building, and it is mostly used in industrial buildings, which should meet the requirements of the application types and basic requirements of building thermal insulation materials.
