25mm Knauf Rocksilk RS45 Universal Insulation Slab is a high-performance mineral wool insulation product suitable for a variety of applications. Manufactured from rock mineral wool using Knauf's unique bio-based ECOSE Technology binder, it provides excellent thermal and acoustic insulation properties.
