Thermo Aspen — STEP Lining
The Step profile brings a chunkier, more architectural edge to Thermo Aspen a modern take on sauna cladding for anyone after something a little different from the norm. It's typically installed vertically, though it works just as well horizontally, and suits both walls and ceilings.
Common uses:
- Feature Walls & Ceilings: A bolder, more contemporary profile that stands out from traditional cladding.
- Vertical or Horizontal Runs: Flexible orientation to suit the design.
- Consistent Colour & Pattern: Carries the same uniform Thermo Aspen finish across every board.
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.
