    Envirocoustic™ Wood Wool - Backfill Acoustical Panels

    Envirocoustic™ Wood Wool – Backfill Acoustic Ceiling and Wall Panels
    Cementitious Wood-Fiber Panels with Integrated Cellulose Acoustical Backing

    Envirocoustic™ Wood Wool Backfill Panels combine the natural aesthetic of wood fiber with advanced acoustic performance. Featuring a built-in cellulose fiber acoustical backer, these composite panels deliver enhanced sound absorption and higher NRC ratings—effectively reducing echo and reverberation in a wide range of environments.

    Ideal for educational facilities, civic buildings, restaurants, and other noise-sensitive spaces, Envirocoustic™ panels are Class A fire-rated and compliant with NFPA 286 fire testing standards. The panels are manufactured from a sustainable blend of wood fiber, Portland cement, and water—making them an environmentally responsible choice that doesn't compromise on performance or design flexibility.

    Available in a variety of sizes, shapes, and colors, the panels can be tailored to complement virtually any architectural style or interior concept. Installation is straightforward: panels can be mounted directly to the substrate without the need for furring strips, simplifying the process and reducing labor costs.
