    Earthwool® Thermal & Acoustic Wall batt: Non-combustible thermal and acoustic insulation

    Earthwool® Thermal and Acoustic Wall batt can be used in both residential and commercial construction types to improve the thermal performance of the building envelope, while also providing superior acoustic performance in external walls and internal partitions. Earthwool® is super-soft to handle and install, and is preferred by installers as it is made with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde. 

    Fire performance

    You can specify Earthwool® Thermal and Acoustic Wall batt with confidence as it has completed AS1530.1 and is not deemed combustible.

    Acoustic solutions

    Earthwool® Thermal and Acoustic Wall batt, when used in warranted Knauf systems, can achieve high levels of acoustic performance for Rw + Ctr requirements for walls, roofs and floors. This makes Earthwool® Thermal and Acoustic Wall batt the ideal solution for high rise residential apartments, shopping centres, office buildings and schools. Earthwool® Thermal and Acoustic Wall batt comes in a range of densities to meet the acoustic needs of individual projects.
