Knauf Earthwool Acoustic Roll 50 mm (covering ~16.2 m²) is a premium glass mineral wool quilt specifically engineered to deliver acoustic performance in internal constructions such as separating walls, floors, and partitions. Manufactured to precise standards using ECOSE® Technology, the product is soft to handle with minimal dust, contains no formaldehyde or phenol, and carries a DECLARE ‘Red List Free’ certification—making it an environmentally responsible choice for modern build environments.
Professional & DIY Insights:
While lower-density (10 kg/m³) Earthwool roll is effective across the mid/high frequency range, acoustics experts note that higher-density materials (e.g. 40 kg/m³) may perform better in absorbing lower frequencies like 125 Hz. Some DIY builders stack layers or pair with air gaps to enhance bass response. However, for standard partitions the 50 mm version provides a well-balanced acoustic solution at lighter weight and cost-effective coverage.
