Knauf Rocksilk RS100 50mm Mineral Wool Insulation Slabs are engineered for projects where reliable fire safety, acoustic control and mechanical strength are required. Each pack provides 4.32m2 of coverage, making them a cost-effective solution for larger installations in both commercial and industrial settings.

Made from durable rock mineral wool, these slabs offer outstanding sound absorption alongside thermal and fire performance. They are completely non-combustible, with a Euroclass A1 fire rating, and maintain integrity at temperatures exceeding 1000°C. This makes them particularly suitable for use in passive fire protection systems and other specialist applications.

The slabs are manufactured with Knauf’s ECOSE® Technology, a sustainable binder that eliminates added formaldehyde. They can also be supplied with a choice of foil or tissue facings, providing flexibility to meet different specification requirements. Lightweight yet strong, Rocksilk RS100 delivers consistent performance across multiple applications.
