DESCRIPTION

The ProSaunas Thermo-Aspen Tongue and Groove 1x5 STS4 Profile is a precision-milled wall and ceiling cladding that brings a distinctly contemporary Scandinavian aesthetic to any sauna interior. The narrow, angular grooves of the STS4 profile produce a clean nickel-gap look — a modern alternative to traditional flush-panel installations — that adds visual depth and a refined, architectural quality to sauna walls and ceilings. The result is a sophisticated contrast effect that works particularly well when combined with other ProSaunas profiles or wood types.

Crafted from premium straight-grained Thermo-Aspen with a uniform texture and warm, rich hue, it is comfortable to the touch even in high heat and does not secrete resin or splinter. Thermal modification enhances dimensional stability, water resistance, and resistance to decay, pests, and fungi through a fully organic process using heat, steam, and pressure — with no chemicals involved. ProSaunas selects only premium wood from Northern Europe and Canada, backed by over 55 years of sauna craftsmanship experience.
