The Harvia WL100 protective bedding is made of aluminum/zinc coated steel that is painted black. The protective bedding is used when, for example, the fireplace or wood burning heater is installed onto a water-proofed tile floor or wooden floor.
Hemfir
Hemfir is lighter in color with small tight knots that give its rustic appearance. Rustic Fir is our most popular lumber for indoor saunas and is also ideal for exterior applications. The exterior of the sauna can be left natural or stained or painted as desired. This lumber is sourced from North America.
