The Knauf Acoustic Roll is a high-performance glass mineral wool insulation designed to deliver exceptional sound absorption while also enhancing the thermal and fire performance of walls, floors, and partitions.

When used in partitions, the roll works in harmony with plasterboard linings by absorbing airborne sound within the cavity, significantly improving acoustic performance without adding unnecessary mass.
