Description
Thermory's SI moulding in dark thermo alder is the corner trim that finishes a sauna interior properly. Fixed where the walls meet and around the edges of the ceiling, its small concave face sits neatly on the cladding and covers any gaps between the panels and the corner of the room. The deep chocolate brown colour matches our other dark thermo alder timber for a consistent, contemporary look. Each pack contains four lengths of 14 × 30 mm trim, available in 2100 mm or 2400 mm.

Timber
Dark thermo alder has a striking dark chocolate brown colour and a strong, toasted scent, the result of intense, fully natural thermal modification. It is a premium timber: elegant, easy to keep clean and well suited to saunas with a contemporary look. As a natural product, timber shows some colour variation between packs and batches.
Fitting
SI moulding is fixed into the corners of the sauna: around the edges of the ceiling and where the walls meet. The small concave face sits neatly on the cladding face and covers any gaps between the cladding panels and the corner of the room. Corner mouldings are often overlooked in DIY projects, but they are an important finishing touch in any sauna build.
Quality & Wastage
Our dark thermo alder timber is A-grade: durable, knot free and with a low risk of splintering. We recommend a wastage allowance of 20–25% for these corner mouldings, which also covers the risk of damage in transit.
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.
