Roots 15×90 STS5 with Groove HT Aspen

Roots 15×90 STS 5 I-Groove Panel Heat-Treated Aspen

The Roots collection showcases authentic 100% Finnish aspen responsibly manufactured – discover the beauty of knotty Finnish aspen.

Our Roots I-groove panel celebrates what others might hide: it is made from Finnish aspen, from the knotty part of the trunk, which is created as a side stream from our knot-free premium production. Each panel tells the story of Finnish forests with its unique grain patterns and natural knots.

From forest to finished product – entirely in Pieksämäki, Finland: The Roots I-groove panel is sawn from Finnish aspen at our own sawmill in Pieksämäki, in the center of Finland. After sawing, we heat-treat the wood to a beautiful brown shade using only hot air and steam. Finally, we plane the product into a 1-groove 15×90 mm STS 5 profile. The product meets A-grade quality in all other characteristics but contains natural knots that make each panel unique.

Versatile applications: A perfect choice for saunas and interior wall and ceiling paneling when you want the natural, knotty appearance of heat-treated Finnish aspen and its beautiful warm tone. Heat treatment enhances the depth of the wood’s hues and makes it resin-free, dimensionally stable, and a pleasant material for humid spaces.

Roots philosophy: This is not just a product – it is our commitment to circular economy and responsible forestry. By utilizing every part of the Finnish aspen we saw, we ensure nothing goes to waste. At the same time, we create something beautiful from what was previously considered secondary material.
