Description
The alder SI moulding is a corner trim that gives the inside of the sauna a clean, considered finish. Fixed into the inward-facing corners where the walls meet, and around the edges of the ceiling, its small, rounded face sits tidily in the corner and conceals any gaps left between the cladding boards. Cut from alder, it shares the light brown colour and warm pink undertones of our alder cladding, along with a low risk of twisting or warping and a subtle scent of freshly cut hay. Each pack contains four A-grade lengths measuring 25 × 25 mm, in a choice of 2100 mm or 2400 mm.

Timber
Alder is a popular choice in traditional saunas thanks to its natural qualities and low risk of twisting and warping. It has a light brown colour with warm pink undertones and a subtle scent resembling freshly cut hay. Alder does not overheat and has water repellent properties, making it well suited to hot and humid environments.
Profile
The SI moulding is fixed into the corners of the sauna: around the edges of the ceiling and in the corners where the walls meet. Its small, rounded face covers any gaps left between the cladding panels. Corner mouldings are often overlooked in DIY projects, yet they are an important finishing touch in any sauna build.
Quality & wastage
Our alder sauna timber is A-grade: durable, knot-free and with a low risk of splintering. We recommend a wastage allowance of 15%, which also accounts for any risk of damage in transit.
Ordering & delivery
Timber orders typically travel on a palletised service with kerbside delivery, and costs vary with size, quantity and postcode. We usually ship lengths up to 2400 mm; where you need a shorter length than we stock, our cutting service can cut a longer board down for a small fee, with the off-cut added to the pallet. For advice on quantities, longer lengths or the cutting service, call +44 (0) 20 8050 2895 or email support@finnmarksauna.com.
