Thermory Thermo-Magnolia 1×7 STS10 wall paneling gives sauna walls and ceilings the broad, clean appearance of magnolia with the stability of thermal modification. The wide 6.7-inch board and STS10 profile create a modern shadow line while hidden fastening keeps the finished surface uninterrupted.

Why choose Thermo-Magnolia?

  • Wide modern profile: 6.4-inch face coverage creates fewer seams and a calm, architectural look.
  • Thermally modified: Heat and steam improve dimensional stability without added chemicals.
  • Comfortable surface: Low thermal conductivity keeps the wood pleasant to the touch.
  • Hidden fastening: The tongue-and-groove STS10 profile supports a clean installation.
  • Suitable for sauna interiors: Use on walls and ceilings in residential or commercial sauna rooms.

PLAN THE WHOLE SAUNA

The room and heater still have to work as one system.

Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
