What Is Mineral Wool Insulation?
Mineral wool insulation is manufactured by melting natural and recycled minerals — typically basalt rock and glass cullet — at extreme temperatures, spinning them into fine fibres and binding them into rigid slabs, boards or rolls. The result is a stable, open-fibre structure that offers exceptional fire resistance, moisture tolerance and long-term dimensional stability.
Stone Wool vs Glass Wool – Key Differences
Stone wool (also known as rock wool) excels in fire safety and acoustic performance, achieving A1/A2 non-combustible classification. This makes it the preferred choice for external wall insulation, high-rise buildings and separating walls. In contrast, glass wool provides lightweight, cost-effective thermal insulation ideal for lofts, internal partitions and service voids. Both variants remain fully compatible with modern EWI systems, while façade-grade stone wool slabs like ROCKWOOL Frontrock Plus and Frontrock Super deliver proven performance in safety-critical applications.
