Rock wool board, also known as rock wool thermal insulation and decorative board, is an inorganic fiber board made from basalt as the main raw material, processed through high-temperature melting. Successfully tested in June 1981, rock wool board is a new type of thermal insulation, fire-retardant, and sound-absorbing material.

Rock wool boards are man-made inorganic fibers processed through high-temperature melting, featuring light weight, low thermal conductivity, heat absorption, and non-flammability. Initially developed, they are commonly used in construction with a variety of application types, particularly suitable for industrial buildings, and should comply with the regulations of "Application Types and Basic Requirements for Building Insulation Materials."
