ProSaunas Thermo-Aspen 1x2 Inside Corner Trim provides a refined, furniture-quality finish for your sauna. Thermo-Aspen is an exceptional material for sauna environments—it does not secrete resin, splinter, or become uncomfortably hot. Its rich golden-brown tone and smooth texture create an elegant, natural aesthetic that enhances any sauna design.

Through a fully organic process using heat, steam, and pressure, thermal modification enhances the wood’s structure, increasing dimensional stability, water resistance, and durability. This process makes Thermo-Aspen superior to untreated wood in resisting decay, pests, and fungi, while maintaining an ideal moisture balance.

ProSaunas sources only the highest-quality wood from Northern Europe and Canada, ensuring exceptional consistency and performance. With over 55 years of experience crafting premium sauna rooms across North America, Prosaunas upholds the strictest quality standards to ensure complete satisfaction.

Please note: In North America, wood sizes are listed as nominal measurements, which may differ slightly from actual dimensions due to drying and surfacing processes. Refer to our diagram for precise measurements.
