Rockwool board, also known as thermal insulation and decorative rockwool board, is an inorganic fiber board made from basalt through high-temperature melting and processing. It was successfully trialed in June 1981. Rockwool board is a new type of insulation, fire-retardant, and sound-absorbing material.

Rockwool boards are artificially inorganic fibers processed through high-temperature melting, featuring lightweight, low thermal conductivity, heat absorption, and non-combustibility. Initially developed, they are commonly used in building applications, particularly in industrial buildings, and should comply with the provisions of "Application Types and Basic Requirements for Building Insulation Materials." 。
