Knauf Rocksilk® RS45 is a high-performance rock mineral wool slab designed for projects that need reliable acoustic absorption, thermal insulation, and fire protection — all from one product. It’s non-combustible and achieves Euroclass A1 reaction to fire classification, with a melting temperature of over 1000°C for longer periods of fire resistance than many mainstream insulants.

RS45 is also manufactured using Knauf’s plant-based binder, ECOSE® Technology, and its mineral wool structure delivers excellent levels of sound absorption and sound reduction.
