Thermo-Spruce Sauna Wood - Wall Paneling 1x6 T&G HN

Thermally Modified Spruce Sauna Wood - Wall Paneling 1x6 T&G HN is crafted from premium Nordic Spruce, thermally modified using only heat and steam for enhanced durability and dimensional stability without the use of chemicals. The thermal modification process gives the wood its characteristic rich golden-brown tone, removes natural resins making it ideal for high-heat sauna environments, and significantly improves moisture resistance compared to untreated wood. The tongue-and-groove profile with hidden fixing creates a seamless, nail-hole-free surface with elegant, narrow shadow lines between panels.

Available Lengths: 2–11.8 ft.

This wood is sold in a bundle of 6 boards.

  • Thermally Modified Nordic Spruce: Resin-free and splinter-resistant - ideal for sauna walls, ceilings, and interior cladding where comfort and cleanliness matter.
  • T&G Hidden Nailing (HN) Profile: Tongue-and-groove with a V-groove on the tongue for concealed fastening - no visible screw holes or nail marks.
  • Dimensionally Stable: Thermal modification significantly reduces wood movement in response to moisture and temperature changes, minimizing warping and shrinking.
  • Chemical-Free Treatment: Modified using only heat and steam - no preservatives, chemicals, or adhesives.
  • Suitable for Sauna & Spa: Resin-free and smooth for comfortable contact in high-temperature environments.
  • Width: 5.59 in (142mm)
  • Thickness: 0.79 in (20mm)
  • Coverage: 4.86 in (123mm) per board
  • Profile: T&G with Hidden Nailing (HN)
  • Material: Thermally Modified Nordic Spruce (ThermoWood®)
