Maximize acoustic performance in internal walls and floors with Knauf Insulation Acoustic Roll, supplied in a ready-cut 100mm thickness. This thick glass mineral wool roll offers high sound absorption and noise reduction properties, engineered to fit tightly between studs to close joints and prevent unwanted air gaps from compromising sound insulation.

Meeting building regulations with a manufactured density in excess of 10kg/m³, this product is tested with all major brands of plasterboard to achieve compliance with Part E acoustic standards. Ready-cut rolls enable quick and easy installation on site, while longer roll dimensions ensure efficient handling, transport, and storage.

The insulation is non-combustible and achieves a Euroclass A1 reaction to fire classification for peace of mind. It is produced using Knauf Insulation's unique bio-based binder, ECOSE Technology.
