Alder is a popular and apt choice for saunas due to its beautiful color and other properties. The intensity of the color is affected by the time of felling, the growth conditions and the drying process. We use alder in sauna benches and the following panel profiles: Kallio, Kallio Groove, STP and finger panel.

Aspen is a traditional choice. It does not conduct heat or splinter, and its even structure ensures a beautiful result when colored. We use aspen in sauna benches and the following panel profiles: Kallio, Kallio Groove, STP and finger panel.

Thermo aspen has a beautiful dark brown shade. Thanks to the thermal modification, it stays dimensionally stable and withstands the conditions of the sauna. The process also imparts a pleasant scent to the wood. We use thermo aspen in sauna benches and the following panel profiles: Kallio, Kallio Groove, STP and finger panel.

Hemlock is light-colored with a hint of reddish brown in the grain. It offers excellent structural characteristics and is likely to gain popularity and more varied applications in the future. We use hemlock in sauna benches and the following panel profiles: Kallio and finger panel.

Cedar is a lightweight and durable option. Its specialty is a beautiful range of colors: the shade of the wood varies from light to dark red to brown. We use cedar in sauna benches and Kallio panels.

Ash is hard, robust and extremely durable. Thermo ash has a dark brown shade. It is available in the Thermo-S and Thermo-D treatment classes. We use thermo ash in terrace boards and the following panel profiles: Kallio and Rombus. Ash can also be used in furniture.

We use Finnish thermo pine in products for both interior and exterior cladding. Thermal modification improves wood’s resistance to decay and weather conditions, its thermal insulation capacity, as well as its dimensional stability with fluctuating moisture levels. The high heat also helps to remove resin. Thermally modified wood is completely non-toxic and well-suited to sustainable and eco-friendly construction.
