Rock wool, also known as mineral wool, is a type of insulation made from natural rock or minerals. It is created by melting these materials and spinning them into fine fibers, which are then compressed into batts or loose-fill forms. Rock wool is known for its excellent thermal insulation properties, fire resistance, and soundproofing capabilities. This material is commonly used in construction for insulating walls, roofs, and floors. It is also environmentally friendly, as it can be made from recycled materials. Additionally, rock wool is resistant to mold and pests, making it a durable choice for various building applications.
