Alder

Alder 1×1 SI makes sauna building easier than ever. These 0.59″x 0.71″ are ideal for concealing the gap and giving a professional finish to any wall-to-ceiling transition. Make it easy, make it beautiful with Thermory 1×1 ceiling mouldings in Alder.

Note: These will arrive directly from Thermory USA in bundles of four in 7′ and 8′ lengths.

The wall profile that makes people stop and ask what species that is. Grace is a wide tongue-and-groove with a precision shadow reveal, and in natural alder the warm reddish-brown tone makes those grooves pop. Each board is 2.52" wide with 2.2" net coverage, milled in Estonia to 1.06" thick. Dramatic for a wall, clean for a ceiling, honestly different from the usual sauna paneling. Pairs with any alder bench board for a matched room. Sold by the linear foot in 1 and 8 ft lengths.

Outside corners are the exposed edges, which means they’re what people see and touch first. This is the alder VA outside corner trim: 1.1" square (1.1 in x 1.1 in), angle-molded to wrap outside corners cleanly in natural alder. Same warm reddish-brown tone as the rest of the ProSaunas alder family, milled in Estonia, E1 certified. Beefier than the inside corner piece at the same 1.1" section, which makes sense: outside corners take contact. At $3.07 per linear foot it finishes the room where the finish matters most. Sold by the linear foot in 1 and 8 ft lengths.

The trim piece that pulls a room together. This is the alder 2×2 S4SEE moulding: 1.1" square (1.1 in x 1.1 in), surfaced four sides with eased edges, milled in Estonia from natural alder. Use it to cap bench edges, frame out a heater enclosure, or add a furniture-quality line wherever you need one. Warm reddish-brown tone matches the alder bench and cladding family exactly. At $3.48 per linear foot it’s the least glamorous piece in the room, but the room looks noticeably better with it. Sold by the linear foot in 1, 8, 9, and 10 ft lengths.
