    Knauf Insulation Earthwool Acoustic Roll (12E)

    Product Description:

    For timber joisted floors, plasterboard partitions and timber separating walls and floors


    Earthwool Acoustic Roll is a flexible glass mineral wool quilt which is lightweight, flexible, resilient and non-combustible. The rolls are 1200mm wide and ready cut to produce 3 rolls 400mm wide or 2 rolls 600mm wide.

    Earthwool Acoustic Roll is manufactured to a minimum density of 10kg/m3.


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

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

    Earthwool Acoustic Roll is specifically designed for friction fitting between resilient timber battens and timber studs in robust detail separating floors and walls and between timber and metal studs in lightweight plasterboard partitions. Earthwool Acoustic Roll provides a high level of sound absorption, whilst also improving the thermal and fire performance of the floor or partition.

    Using 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 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.


    • Excellent sound absorption properties
    • Lightweight, and easy to install
    • Dimensioned to suit studs and joists at 400mm or 600mm centres
    • Long roll lengths for quick and economic Installation
    • Friction fits between studs, ensuring continuity of the absorbent layer with no air gaps

    Ecose Technology ensures an evironmentally friendly formaldehyde-free binder made from rapidly renewable bio-based materials.
