Description
The Thermory alder bench module is a ready-made sauna bench element with a 140 mm finger-jointed and glued front board, a quick and straightforward route to benching in a DIY sauna build. It is sold in widths of 400, 500 and 600 mm and lengths of 2.1 m and 2.4 m, with individual boards 90 mm wide, and the frame and front board are sawn to length during installation for an exact fit. A central support between the bench and the floor, with a minimum cross-section of 28 × 42 mm, is required and is not included. Alder is a popular sauna timber with a light brown colour and warm pink undertones; it does not overheat and has water-repellent properties. Ready-made modules are an entry-level, budget-friendly option; for bespoke benching in market-leading materials, ask about the Finnmark Bench Fabrication Service.
Features
Technical Specification
| All modules | |
| Timber | Alder |
| Front board | 140 mm, finger-jointed and glued |
| Individual board width | 90 mm |
| Widths available | 400, 500 or 600 mm |
| Lengths available | 2.1 m or 2.4 m |
| Front board fixing | Angle connectors; refitted with 5 × 70 mm screws |
| Support and frame fixing | 5 × 100 mm screws (two per wall support; maximum 600 mm spacing along the frame) |
| Central floor support | Required, minimum 28 × 42 mm cross-section (not included) |
| Production tolerances | Thickness ±0.5 mm; cover width ±2.5%; length +10/–3 mm per metre |
Installation
Measure the sauna room first, allowing a gap of at least 4–5 mm between the bench and the wall at both ends of the module. The front board is detached (on the 140 module it is fixed to the frame with angle connectors), the frame end piece is repositioned, and the frame, front board and bench grate are sawn to the required length. The wall supports are fixed with two 5 × 100 mm screws each, set at the same height from the floor; raised sections on their outer edges maintain ventilation between the wall and the module. The frame is then screwed to the wall, including along its back edge, using the remaining 5 × 100 mm screws at no more than 600 mm spacing, and the front board is refitted with 5 × 70 mm screws. A wooden support between the bench and the floor, with a minimum cross-section of 28 × 42 mm, must be added at the centre of each bench and is not included. All wooden parts should be treated with a wood preservative to protect against moisture, most conveniently before installation; the manufacturer is not responsible for damage caused by incorrect installation or untreated timber, so the installation guide must be followed.
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 reminiscent of freshly cut hay; it does not overheat and has water-repellent properties, making it well suited to hot and humid environments. Thermory grades its alder on the better (visible) face under its published grading rules, with two grades, A and B.
Brand
Thermory, founded in Estonia in 1997, is the world’s largest manufacturer of thermally modified wood and a specialist in durable, chemical-free sauna timber.
