Stone wool boards, also known as thermal insulation and decorative stone wool boards, are inorganic fiber boards made by melting and processing basalt at high temperatures. Successfully trialed in June 1981, stone wool boards are a new type of thermal insulation, fire-retardant, and sound-absorbing material.

Rockwool boards are man-made inorganic fibers processed through high-temperature melting, featuring light weight, low thermal conductivity, heat absorption, and non-combustibility. Initially developed for common applications in construction, they are predominantly used in industrial buildings and should comply with the provisions of "Application Types and Basic Requirements for Building Thermal Insulation Materials." [1]  。
