Knauf Insulation Acoustic Roll (Ready Cut) 50mm

Enhance sound absorption and reduce noise transmission in your building projects with Knauf Insulation Acoustic Roll, supplied in a ready-cut 50mm thickness. Designed for use in internal wall and floor applications, this glass mineral wool roll is specifically dimensioned to friction-fit between studs to close joints, reducing the potential for unwanted air gaps and maximizing acoustic performance.

Manufactured with a density in excess of 10kg/m³, this insulation meets building regulations and has been tested with all major brands of plasterboard to achieve compliance with Part E sound insulation requirements. The ready-cut format enables quick and easy installation, while longer rolls ensure efficient handling, transport, and on-site storage.

Safety and sustainability are core to its design, featuring a non-combustible Euroclass A1 reaction to fire classification. It is manufactured using Knauf Insulation's unique bio-based binder, ECOSE Technology, providing an environmentally considerate insulation choice.
