Fibertex® 650 Stonewool Insulation Board & Blanket
Bradford Fibertex 650 is a high-density, non-combustible Stonewool bulk insulation supplied unfaced as boards and blankets for high-temperature industrial applications (up to 650 °C). Its high density delivers strong thermal resistance and effective acoustic absorption in a compact profile for space-limited installations, providing reliable thermal, acoustic and fire performance in a cost-effective format.
Features and Benefits
Bradford Fibertex 650 insulation boards and blankets are easy to handle, cut cleanly and conform to complex shapes for a neat, secure fit. The unfaced formats are shape-stable and resist compression during handling, helping maintain consistent coverage. Bradford Fibertex 650 maintains performance after contact with water, and its biosoluble fibres are safe to handle, offering a durable, cost-effective solution for demanding industrial environments.
