Thermally modified timber (TMT) has seen rising demand in New Zealand as architects and designers seek more sustainable, dimensionally stable alternatives to chemically treated products. JSC’s TMT range brings this globally proven technology to the local market with a broad selection of grades, profiles and finishes — all manufactured from solid timber without laminations, glues or added chemicals.
Using only heat and steam, the thermal modification process enhances the durability and stability of the timber, making it suitable for a wide range of project types and applications — from exterior cladding and battens to interior panelling and screening.
What sets JSC’s range apart is the level of design flexibility it offers. The range includes options such as Taiga, Amba, and Taxon, with each species offering distinct tonal and textural qualities. Architects can specify clear or rustic grades depending on the project’s intent, with options including bandsawn or brushed finishes for exteriors, or dressed finishes for internal use.
To support creative expression and longevity, JSC offers a complementary JSC Coatings Range, including JSC Scumble and JSC Coda, formulated specifically for compatibility with thermally modified timber. With over 25 architectural colour options available across the range, the coatings allow designers to align timber aesthetics with wider material palettes and project goals. These coatings provide a broad palette — including dark tones — while supporting longer recoating intervals. Importantly, they are environmentally safe and designed to enhance the natural characteristics of the timber.
JSC’s TMT products have already been selected for a range of residential, commercial and public sector projects, including housing developments and educational facilities, where durability, natural aesthetics, and extended maintenance intervals are critical.
By offering a stable and versatile timber solution made through a natural modification process, JSC provides designers with an innovative alternative.
