It can be installed using existing panel handling and installation methods. Suitable for interior built environment applications including:

  • Shop fittings.
  • Wall cladding and ceilings.
  • Ephemeral projects.
  • Joinery and furniture parts.


The HONEXT® Panel is the next-generation fibreboard. Its sustainability profile comes from the raw material sourcing, the end-of-life solutions that it allows and the distinctive manufacturing process. It is manufactured through the carbon-neutral, bio-based industrial HONEXT® process, which is resin-free, zero-waste and reinforces the bonds between cellulose fibres.

Features and benefits:

  • Fully recyclable, non-toxic, and entirely made from upcycled waste fibres.
  • Particularly suitable for interior use, with competitive mechanical and thermodynamic properties.
  • Flexible and lighter than traditional MD fibreboards.
  • No added VOCs.
  • Cradle to Cradle Silver Certified and Material Health Silver Certified.
  • Greater sound absorption properties than traditional building materials.
  • Resistant to moisture, water vapor and fire.
  • Can be finished with all decorative applications for the aesthetics and performance qualities desired for final applications.
  • Can be laminated and combined with other materials using common production techniques.
  • Durability of at least 25 years in use.
