    Highly durable with natural beauty, the Thermory Thermo-Spruce profile offers a natural rustic appearance for any sauna. It's rounded edges and narrow grooves between broad boards make it a perfect companion for combination with other profiles to create a unique look and feel. The color of thermally modified spruce is an attractive golden brown. Wonderfully fresh with a hint of citrus, the distinctive pine fragrance is known to fill the space around it.

    Thermory’s sustainably sourced, thermally modified spruce is rot-resistant, offers exceptional durability, and stands up to moisture. This completely chemical-free process uses only heat and steam which alters every fiber of the wood, creating a stable product that is the best sauna wood for the extreme atmospheric conditions in sauna rooms.  Thermory offers thermally modified spruce with the Nordic Swan Ecolabel, which certifies that the wood originates from responsibly managed forests, is free of chemicals and is extremely durable when used outdoors.

    The wood’s reduced moisture absorption capability and rate from thermal modification results in less moisture-induced deformation. The thermal modification gives spruce the highest durability rating (class 1, 25+ years) so your façade will look great for decades.

    Norway spruce is a coniferous tree of the pine family in the genus Picea, that is widespread in Europe. Without any treatment, spruce wood is lightweight, soft, and almost white in color with medium mechanical properties. Spruce splits more easily than pine but it is less resinous. The wood is very well suited for thermal modification, which makes it significantly more durable and stable while also giving it a beautiful golden-brown tone.

    As with any wood, the surface of thermally modified spruce will fade to a natural silver-gray color over time. This process starts immediately after the products are installed and can take a few months to several years depending on how much UV light they are exposed to. The durability of the boards is not affected.

    If you would like to preserve the darker tone of thermally modified wood, we recommend oiling the boards once a year using UV-resistant oil.
