Rock wool insulation, also known as mineral wool or stone wool, is a type of insulation made from natural rock or recycled materials. It is created by melting the raw materials and spinning them into fibers, which are then formed into batts, boards, or loose-fill. This insulation is known for its excellent thermal performance, helping to keep buildings warm in winter and cool in summer. In addition to thermal insulation, rock wool also provides soundproofing benefits and is fire-resistant, making it a popular choice for both residential and commercial buildings. Its ability to resist moisture helps prevent mold growth, contributing to healthier indoor air quality.
