Insulation Material Made From Natural Rock Or Stone

Rock wool, also known as mineral wool, is a type of insulation material made from natural rock or stone. 

It is commonly used in construction to provide thermal and acoustic insulation for buildings. 

Rock wool is non-combustible and has a high melting point, making it a safe choice for fire protection. It is also resistant to moisture and mold, making it a durable and long-lasting insulation option. Rock wool can be easily installed in walls, ceilings, and floors, and is available in a variety of thicknesses and densities to suit different insulation needs.
