Accoya Natural
If you're after the best-performing timber available for a sauna, Accoya Natural is about as good as it gets. It's a premium modified wood — sustainably sourced softwood that's been through an advanced acetylation process, changing its cell structure to deliver a level of durability, stability, and moisture resistance that traditional timbers simply can't match. Locally milled into profiles here in Australia, it's a genuinely premium option for anyone who wants the very best in their sauna build.
Why it's the best of the best:
- Backed by a 50-Year Warranty: Accoya is the only timber in the world to carry a warranty this long — a real reflection of how confident the process is in its own durability.
- Changed at a Cellular Level: The acetylation process alters the timber's natural cell structure, dramatically reducing its ability to absorb moisture and cutting the swelling, shrinking, and warping that comes with humidity and heat cycling.
- Naturally Resistant to Rot and Pests: Because its cell structure is changed, fungi can no longer break it down and insects can't digest it — giving it exceptional natural resistance to decay without any toxic treatments.
- Stays Cooler to the Touch: Thermal testing shows Accoya performs significantly better than comparable timbers in direct heat, staying noticeably cooler even in high-temperature sauna conditions.
- Coatings Last Longer: Because the timber moves so little, any coating applied holds up far longer than on timber that keeps expanding and contracting — extending time between maintenance.
- Exceptional Longevity: Built to handle the demanding heat and humidity of daily sauna use for decades, with minimal movement and minimal upkeep.
About the finish: Accoya Natural carries a clean, light natural tone, milled locally into cladding and lining profiles suited to sauna interiors and exteriors alike.
