Rock wool board, also known as thermal insulation and decorative rock wool board, is an inorganic fiber board made by melting and processing basalt at high temperatures. The trial production of rock wool board was successfully conducted in June 1981. It is a new type of thermal insulation, fire-retardant, and sound-absorbing material.

Rockwool boards are artificial inorganic fibers processed through high-temperature melting, featuring lightweight, low thermal conductivity, heat absorption, and non-flammability. Initially developed for common applications in construction, they are often used in industrial buildings and should comply with the regulations of "Application Types and Basic Requirements for Building Insulation Materials."
