Wood for saunas
The eight woods we work with – each has its own tone, feel and durability.
Siberian spruce
Siberian spruce grows slowly in a cold climate, so it has dense growth rings and few knots. For saunas we use grade A+ without resin pockets. A light tone, a delicate scent and the best value for money.
Thermo spruce
Heat treatment at 200 °C removes resin and moisture from the spruce, giving it a darker caramel tone and dimensional stability. It does not crack or warp and withstands moisture even outdoors.
Thermo pine
Siberian pine after heat treatment: dense, honey-brown, with a bold grain. The most popular choice for exterior cladding and sauna house facades; it copes well with changing weather.
Aspen
Aspen has no resin or knots and stays cool to the touch even at 90 °C, which is why it is the first choice for benches and backrests. Light, almost white, with a silky surface.
Alder
Alder has a gentle honey-pink colour and a smooth, resin-free surface. The traditional sauna wood of Finnish and Estonian makers, pleasant to the touch and stable in humidity.
Thermo aspen
Heat-treated aspen: a deep chocolate tone, minimal water absorption and the highest dimensional stability. An elegant contrast to light walls, also suitable for benches.
Siberian larch
Siberian larch is a hard, resin-rich wood that resists the elements naturally without chemicals. It turns silver-grey with age, or you can treat it with oil.
Charred larch
The Japanese technique of charring the surface: the larch is charred, brushed and oiled. A charcoal-black facade with a bold grain, a long life and minimal maintenance.
