Knotty Canadian Western Red Cedar Tongue & Groove Sauna Boards

Bring authentic warmth, natural character and the unmistakable appearance of cedar into your sauna with our 1×4 Knotty Canadian Western Red Cedar tongue-and-groove boards. Milled in a Tight Knot grade, kiln dried for improved stability and finished with a traditional V4E profile, these boards are an excellent choice for sauna walls, ceilings and decorative interior wood paneling.

Every board displays its own combination of grain, colour variation and sound natural knots. The result is a sauna interior that feels warm and inviting without looking overly uniform or manufactured. Knotty cedar works equally well in traditional Canadian cottage saunas, contemporary home wellness rooms and commercial sauna projects where natural wood character is part of the design.

Why Western Red Cedar Is an Excellent Sauna Wood

Western Red Cedar, botanically known as Thuja plicata, is valued for its low density, dimensional stability, distinctive aroma and natural durability. Because it is lightweight and contains a high proportion of air spaces within its cellular structure, Western Red Cedar offers strong insulating properties compared with many denser materials. Its relatively low shrinkage also helps reduce excessive movement as humidity and temperature conditions change.

The heartwood contains natural extractives that contribute to resistance against decay and insect damage. These characteristics, together with its workability and attractive colour range, have made Western Red Cedar a widely used material for sauna paneling, interior walls, ceilings and architectural woodwork.
