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.
The Harvia WL400 protective sheath is designed and approved for wood-heated Harvia wood burning heaters (Harvia M1, M2, M3 and M3 SL). The protective sheath considerably reduces the safety distance to combustible materials – in practice, this makes the wood burning heater fit in a smaller space.
The protective sheath is attached to the wood burning heater and conforms to the shape of the wood burning heater, making the combination sleek. As the Harvia protective sheaths are wood burning heater model-specific, no compromises have been made in terms of design or performance.
The protective sheath is available both as a full version and as a one-sided sheath, which can be installed on either side of the wood burning heater. The protective sheaths are made of steel sheet that is painted black. If you also need to protect your floor, the black WL100 protective bedding matches the style.
