Rockwool board, also known as thermal insulation and decorative rockwool board, is an inorganic fiberboard made by melting and processing basalt at high temperatures. It was successfully trial-produced in June 1981. Rockwool board is a new type of 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 for various applications, especially in industrial buildings, and should comply with the regulations of "Application Types and Basic Requirements for Building Insulation Materials."
