Description
Thermory's STS4 thermo alder cladding dresses the walls and ceiling of a sauna in slim, angular grooves, with the 4 mm gap between boards that gives the profile its name. The result is a strong, symmetrical surface that suits contemporary saunas, and it combines readily with other board profiles when a more individual finish is wanted. Thermo alder itself carries a hazel-brown colour and a subtle texture; like other heat-treated timbers it has a low risk of warping and twisting, and it will not splinter or overheat at sauna temperatures. Each pack contains six boards, 15 mm thick and 90 mm wide with an 80 mm effective width, in a choice of 2100 mm and 2400 mm lengths.

Timber
Thermo alder has a hazel-brown colour and a subtle texture favoured by many. Like other heat-treated timbers it has a low risk of warping and twisting, and it will not splinter or overheat at sauna temperatures.
Profile
The STS4 profile takes its name from the 4 mm gap between boards. Its slim, angular grooves create a symmetrical, strong aesthetic, which makes it a popular choice in modern and contemporary saunas. It can be used alongside other wood profiles to create a unique interior.
Quality & Wastage
This thermo alder is A-grade: durable, knot-free and with a low risk of splintering. We recommend a 15% wastage allowance, which also covers the small risk of damage in transit; our interactive Cladding Calculator can help estimate quantities. As a natural product, timber shows some colour variation between packs and batches, and general sauna wood grading standards apply.
Installation & Care
The cladding is well suited to DIY installation. An Installation and Maintenance Guide is available under the Downloadable Files tab on this page.
Brand
Thermory AS, founded in Estonia in 1997, is the largest manufacturer of thermally modified wood in the world, known for fully natural, chemical-free heat-treated timber.
Ordering & Delivery
Timber orders travel on a palletised shipping service owing to their size, and may require a kerbside drop or handballing off the vehicle. Costs are calculated at checkout by order size and quantity, and differ between UK Mainland, Highland and Island postcodes. We normally ship lengths up to 2400 mm; beyond that, shipping costs rise significantly. If we stock a longer length than you need, our cutting service can cut a full-length board down for a small fee, with the off-cut added to the pallet. For longer lengths, the cutting service, or advice on sizes and quantities, call +44 (0) 20 8050 2895 or email support@finnmarksauna.com.
