TMT Taiga (Lunawood)
Feature Grade Thermally Modified Timber with Butterfly Knots
This feature-rich timber has a light brown and mostly consistent tone with “butterfly knots” showing up at regular intervals that give cladding and interiors a completely unique personality. 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
- Ability to accept darker coatings and stains (both oil and water-based), including black with a significant reduction in dimensional movement
- Aesthetically pleasing knot detailing, without compromising on quality or stability, provide an architectural detail
- Easily workable and easy to maintain
- Non-toxic and chemical-free, with a low environmental impact (treatment process)
- No glue or lamination

FAQ
Frequently Asked Questions
- TMT Taiga has rich warm brown tones and “butterfly knots” showing up at regular intervals that give cladding and interiors a completely unique personality.
- TMT Taxon has a soft, even-grained appearance with minimal knots and a variation of deeper chocolate tones.
- TMT Tuscan is a clearer grade option with a mostly uniform tone, with some tonal variation between boards. It is lighter than TMT Taxon but darker than TMT Amba
- While TMT Amba is the lighter, clearer grade option with a similar light uniform golden brown tone to TMT Taiga but without the knots.
Yes. Thermal modification is an environmentally friendly process. It is a chemical-free process that uses only heat and steam.
Yes. The thermal modification process does not change the combustibility of the timber.
Thermal modification is an environmentally friendly process resulting in an exceptionally stable, highly durable, and aesthetically pleasing timber – all desirable properties for bespoke cladding profiles.
Thermal modification is a conceptually simple process - suitable timbers are subjected to high temperatures using heat and steam in a controlled environment without the use of any chemicals. Once the process is complete, the equilibrium moisture percentage of the modified product is around 4-7%.
The thermal modification process permanently alters the cell structure which enhances the physical properties of the timber. The result of this is that the timber has a greatly reduced capacity to absorb moisture. With the reduction of moisture absorption, the timber is much less susceptible to cupping, expansion, contraction, or distortion caused by seasonal changes in the environment. Due to the thermally modified process that the timbers undergo, all the sugars and tannins in the wood are baked, removing the food source from fungi and insects as well as hardening and darkening the wood. You will see all TMT options come in rich brown tones and are suitable for a variety of interior and exterior applications such as exterior claddings, interior linings, battens, and more depending on the species you choose
