Description

Thermory's SHP bench boards in thermo alder are the quiet backbone of a well-built sauna bench. Heat treatment gives the alder a rich hazel-brown colour and a stable, splinter-free structure that stays comfortable at sauna temperatures. The full 28 mm thickness guards against warping and twisting, and the R3 radiused edges are smooth against the skin. Boards are 90 mm wide and supplied in packs of four, in 2100 mm or 2400 mm lengths, suited to a DIY build or our sauna bench fabrication service.

Features

  • Rich hazel-brown tone: Thermal modification gives the alder a deep, even colour and subtle texture.
  • Comfortable at temperature: Thermo alder will not overheat or splinter in sauna conditions.
  • Stable 28 mm thickness: The full-thickness board resists warping and twisting over time.
  • Smooth R3 edges: A 3 mm radius on each corner leaves the bench edge soft against the skin.
  • Chemical-free treatment: Thermory's thermal modification uses only heat and steam, with no added chemicals.
  • A-grade, knot-free timber: Graded for durability with a low risk of splintering.
  • DIY or fabricated: Use the boards in your own build, or through our sauna bench fabrication service.

Timber

Thermo alder has a hazel-brown colour and 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. See the full Thermo Alder Sauna Wood range.

SHP profile

SHP is the standard profile for sauna bench boards: a rectangular section with radiused corners, usually R2, R3 or R4 (a 2, 3 or 4 mm radius on each edge). The 28 mm thickness is important to prevent warping and twisting over time. More timbers in this profile: SHP Sauna Bench Board Collection.

Quality & Wastage

A-grade timber: durable, knot free and with a low risk of splintering. We recommend a 15% wastage allowance for these bench boards, which also covers the risk of damage in transit. General sauna wood grading standards apply; the grading rules are in the Downloads section on this page. As a natural product, timber shows some colour variation between packs and batches.

Installation

The boards suit a DIY bench build, or our Sauna Bench Fabrication Service can create your ideal bench system.

Ordering & Delivery

Shipping is calculated at checkout and varies with order size and postcode; many timber orders travel on a palletised service and may be a kerbside delivery. Lengths up to 2400 mm ship at standard rates, and a cutting service is available to reduce shipping costs on longer timbers. Contact support@finnmarksauna.com or +44 (0)20 8050 2895.
