Premium Thermo Poplar Wood

Carbon Smart™ saunas are crafted exclusively with Thermo Poplar, a sustainably sourced and thermally modified wood that delivers exceptional performance and a beautiful aesthetic for your sauna interior.

Thermo Poplar

A thermally modified wood treated at approximately 374°F for optimal indoor sauna use. This medium modification delivers enhanced dimensional stability, improved resistance to humidity and temperature fluctuations, and a warm, rich tone—all achieved through a chemical-free process. Ideal for creating a naturally beautiful, long-lasting sauna environment. As part of the Carbon Smart™ line, this wood is responsibly sourced to support carbon-smart forestry practices.
