25mm Knauf Acoustic P/Roll (24m2 Pack)

Earthwool Acoustic Roll is a flexible glass mineral wool quilt which is lightweight, flexible, resilient and non-combustible. Earthwool Acoustic Rolls are 1200mm wide and ready-cut to produce three, 400mm wide rolls, or two, 600mm wide rolls and manufactured to a minimum density of 10Kg/m³.

Earthwool Acoustic Roll is specifically designed for friction fitting between joists and studs at 400mm and 600mm centres to improve the sound insulation of:

• separating walls and floors
• internal walls and floors
• timber and metal stud partitions

Earthwool Acoustic Roll is also designed for friction fitting between resilient timber battens and timber studs in Robust Detail separating floors and walls.

Earthwool Acoustic Roll provides a high level of sound absorption, whilst also improving the thermal and fire performance of the wall, floor or partition. Using glass mineral wool as a sound absorbent layer in partitions and floors significantly improves their acoustic performance, whilst only adding minimally to the overall mass of the structure. In partitions glass mineral wool complements the plasterboard linings by absorbing airborne sound in the cavity and reducing reverberation, it is particularly effective at preventing the hollow sound that can occur in partitions with unfilled cavities.
