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

Rockwool boards are artificial inorganic fibers produced through high-temperature melting processing, featuring lightweight, low thermal conductivity, heat absorption, and non-combustibility. Initially developed, they are commonly used in building applications, with a wide range of types. For industrial buildings, they should comply with the "Application Types and Basic Requirements for Building Insulation Materials."
