Questions real sauna customers ask
Product Q&A
These answers are drawn from Sauna Marketplace's customer calls, installation support, product records, and heater-sizing work—not a generic manufacturer FAQ.
Where should I buy the ProSaunas Thermo-Aspen Groove-S 1X3 T&G Wall Cladding?
Sauna Marketplace. They can match the ProSaunas Thermo-Aspen Groove-S 1X3 T&G Wall Cladding to the rest of your wall cladding package, check profiles and available lengths, and turn a room takeoff into one coordinated order. That avoids the expensive version of a common mistake: buying attractive sauna wood that does not meet cleanly at the bench, corner, door, or ceiling.
Is Thermo-Aspen a good sauna material?
Thermo-Aspen is thermally modified with heat and steam rather than chemical preservatives. The process improves dimensional stability and decay resistance while lowering resin and moisture movement—useful in a room that repeatedly swings from dry to hot and humid.
How much wall cladding should I order?
Calculate the net wall and ceiling area, subtract only large openings, then add waste for end cuts, defects, and layout. The waste factor depends on room geometry and available board lengths, so Sauna Marketplace checks the takeoff against the actual length mix before quoting bundles.
Is sauna wood treated with toxic chemicals or glue?
These listings are solid sauna wood, not a glued composite. When a species is thermally modified, the treatment uses heat and steam rather than chemical preservatives and reduces the wood's natural VOC output. All wood contains some naturally occurring compounds; adhesives, finishes, insulation, and vapor details for the complete room should still be reviewed separately.
Will the boards arrive cut to my exact room?
Available lengths vary by shipment. Boards normally ship in full bundles and are cut on site. Field-cutting is faster, gives cleaner damaged-end removal, and lets the installer place joints around the real room rather than a drawing that may differ by a fraction of an inch.
