Description
Thermory's Ignite cladding starts with aspen boards and embosses them with the distinctive Ignite pattern, creating a truly individual sauna interior. The boards use the STS4 profile: slim, angular grooves and a 4 mm gap between boards for a strong, symmetrical look that suits contemporary saunas. Tongue and groove fitting keeps installation straightforward across walls and ceilings, and the profile can be combined with our other cladding options for contrast. Each pack contains six boards at 15 × 120 mm with a 110 mm effective width, in 2100 mm or 2400 mm lengths.

Timber
Ignite boards are aspen, embossed with our distinctive Ignite patterns to help create a truly unique sauna design. As a natural product, timber shows some colour variation between packs and batches.
Profile
STS4 takes its name from the 4 mm gap between boards. The slim, angular grooves suit a modern sauna where a symmetrical, strong aesthetic is desired, and the profile is a popular choice in contemporary interiors. It can be combined with other profiles for a unique finish.
Quality & Wastage
This timber is A-grade: durable, knot free and with a low risk of splintering. We recommend a wastage allowance of 15%, which also covers the risk of damage in transit. Our wastage allowance guide and interactive calculator on finnmarksauna.com will help you work out quantities. The general sauna wood grading standards apply; grading rules for each timber type are published on finnmarksauna.com.
Installation & Care
The tongue and groove boards are easy to install and well suited to DIY sauna projects, as well as other interior finishes. An installation and maintenance guide for our sauna wood cladding is available in the Downloads section of this page.
Brand
Thermory, founded in Estonia in 1997, is the world's largest manufacturer of thermally modified wood. Its fully natural, chemical-free thermal modification sits alongside a wide selection of untreated sauna timber.
Ordering & Delivery
Timber orders travel on a palletised shipping service and may require a kerbside drop. We normally ship lengths of up to 2400 mm. If you need a shorter length than we stock, our cutting service can cut a longer board down for a small fee; the off-cut is added to the pallet. For longer lengths, the cutting service or advice on quantities, contact support@finnmarksauna.com or call +44 (0) 20 8050 2895.
