TMT Taiga Lunawood

TMT Taiga (Lunawood)

Feature Grade Thermally Modified Timber with Butterfly Knots

Rustic, feature-grade thermally modified timber. With beautiful knot detailing and natural characteristics,  JSC TMT Taiga is our feature-grade thermally modified timber offering. With a more unique ‘knotted’ appearance, TMT Taiga is suitable for use across a range of interior and exterior applications, including cladding, interior linings, battens, and more.

The chemical-free, thermal modification process finishes the timber in a rich brown tone, enhancing the knot detailing. It is sourced from Oy Lunawood Ltd in Europe and profiled locally by JSC into New Zealand-approved profiles.

Key properties of JSC TMT Taiga

  • Enhanced durability and stability
  • Low susceptibility to fungal decay and moisture retention
  • Consistent, rich natural colour

Uses of the TMT Taiga Range

Supplied in random but typically longer length spread, giving greater flexibility and design potential, TMT Taiga can be used for a variety of applications such as cladding, interior timber panelling, screen and battens, and more. See the information sheet for more information.

For the fixing of TMT Taiga weatherboards, only Stainless Steel fastenings must be used. For compliance documentation please contact us.
