Aspen is one of the most popular hardwood species used for sauna construction and interior finishing. It is valued for its light natural tone, comfortable thermal conductivity, and resistance to humid environments. Aspen has been used for decades in traditional Finnish saunas and modern saunas for both cladding and bench construction.

Alder is one of the most expressive hardwood species used for sauna and steam room interiors. It is valued for its warm pinkish-honey tone, attractive grain pattern, and resistance to moisture and high temperatures.

Historically, alder has been used for structures exposed to water. In sauna interiors, it creates a richer and warmer atmosphere compared to lighter species such as aspen and linden.

Thermo aspen is aspen wood that has undergone thermal modification at high temperatures without the use of chemical additives. During treatment, the wood gains a more stable structure, reduced moisture absorption, and a deep, refined tone.

Thermo aspen combines the natural qualities of aspen with enhanced resistance to temperature and humidity fluctuations, making it a highly востребованный material for modern saunas.
