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

Rock wool boards are artificial inorganic fibers processed through high-temperature fusion, characterized by light weight, low thermal conductivity, heat absorption, and non-flammability. Initially developed, they are commonly used in the construction industry, particularly in industrial buildings, and should comply with the provisions of "Application Types and Basic Requirements for Building Insulation Materials."
