Mineral wool insulation is a durable and fire-resistant material made from natural or synthetic fibers, typically derived from rock (basalt) or industrial slag. Widely used in HVAC systems, it offers excellent thermal insulation and can withstand both low and high temperatures, making it suitable for a broad range of applications. Its structure also provides good sound absorption and moisture resistance.
As a traditional and cost-effective alternative to fiberglass insulation, mineral wool is valued for its sustainability and versatility. Common types include rock wool (from natural stone), slag wool (from industrial byproducts), and fiberglass-free variants that avoid synthetic glass content, offering safer handling in sensitive environments.
