1
Surface prep: Wall must be clean, dry, and flat. Suitable for plasterboard, concrete, brick, and timber stud walls. Ensure surface is level, as panels will follow any unevenness.
2
Acclimatise: Leave panels in the installation room for 24–48 hours before fitting. Wood veneer expands and contracts with humidity. This prevents warping after installation.
3
Fixing method: Three options: construction adhesive (MS polymer or PU), concealed clip system, or direct screw through felt backing into studs. Adhesive gives cleanest finish; clips allow future removal.
4
Layout & cutting: Plan panel layout before fixing. Cut with fine-tooth hand saw, circular saw, or mitre saw. Always cut from the wood face side down to prevent tear-out on the visible surface.
5
Finishing: Panels arrive ready to install, with no staining, sealing or finishing required. For walls near moisture (bathrooms, kitchens), apply a thin coat of wood wax or oil to the veneer surface before installation.

The PET felt backing is GRS (Global Recycled Standard) certified, made from post-consumer recycled plastic bottles. Using recycled felt instead of virgin materials significantly reduces embodied carbon compared to conventional acoustic products.

  • GRS certified recycled PET felt backing
  • Natural wood veneer, responsibly sourced
  • No formaldehyde or harmful adhesives
  • Low VOC: safe for indoor air quality
  • Long lifespan: reduces replacement waste
  • Panels can be removed and reused
