Mineral wool, also known as rock wool or slag wool, is an insulation material made from natural or recycled minerals. It is produced by melting these materials and then spinning them into fine fibers. This process creates a lightweight, fire-resistant product that is effective in reducing heat transfer, making it popular for use in buildings and industrial applications. In addition to insulation, mineral wool is also used for soundproofing and as a growing medium in horticulture. Its fibrous structure allows it to trap air, providing excellent thermal and acoustic properties. Mineral wool is considered environmentally friendly due to its recyclable components and energy-efficient production methods.
