25mm Knauf Acoustic Roll 11.1m x 1.2m (4 x 600mm) 26.64m²

Knauf Insulation Acoustic Roll is a glass mineral wool insulation roll designed to reduce airborne sound transmission in internal walls and floors. Manufactured with a high, consistent density, it is engineered to absorb sound effectively between studs and joists, helping create quieter, more comfortable internal spaces. The roll format allows for fast installation and a close fit within standard timber or metal framing, making it suitable for both residential and commercial projects.
