Thermo Aspen — Dressed All Round (DAR)
Dressed All Round means the timber has been machined and planed smooth on every face, giving a clean, finished surface. Thermo Aspen is a go-to choice wherever a smooth, cool-to-touch timber is needed throughout the interior of a sauna.
Common uses:
- Sauna Benches & Bench Frames: A smooth, resin-free surface that's comfortable to sit on, with real stability to hold a frame together over time.
- Bench Face Pieces & Backrests: Consistent colour and a cool touch make it ideal for anywhere skin makes direct contact.
- Duckboards: A practical, good-looking option for sauna floor duckboards.
Thermo Aspen
Thermo Aspen offers something different to a timber like Western Red Cedar — where cedar is prized for its natural grain variation and colour movement, Thermo Aspen is the choice for anyone after a clean, consistent look. It's put through a thermal modification process, using nothing but heat and steam, that transforms raw aspen into a stable, durable timber built specifically for the demands of a sauna.
Why choose Thermo Aspen:
- Consistent, Even Colour: The thermal process darkens the timber into a warm honey-brown to caramel tone, naturally and evenly, without stains or chemicals — a great option if you want a uniform finish rather than cedar's board-to-board variation.
- Built for Stability: The heat-treatment process dramatically reduces moisture content in the timber, which is what makes it so resistant to warping, cracking, and movement inside a sauna's heat and humidity cycles.
- Genuinely Durable: That same process also removes the natural sugars in the timber, making it naturally resistant to mould, fungi, and pests, on top of the moisture resistance.
- Resin-Free: No sticky sap on hot benches and no resin bleed, a cleaner, more comfortable surface than a lot of traditional sauna timbers.
- Harder and More Resilient: The treatment process leaves the timber noticeably harder and more durable, suited to the daily wear of a busy sauna.
- Sourced from Estonia: Grown and processed using advanced thermal modification techniques from Estonian timber.
Available in a range of sizes to suit different builds.
