When it comes to crafting the perfect outdoor sauna, the comparison between Thermowood and Cedar is crucial. Thermowood’s advanced properties, stemming from its unique production process, give it an edge over Cedar in various aspects. Outdoor saunas are a sanctuary for those seeking relaxation, wellness, and rejuvenation. The choice of wood plays a pivotal role in maximizing the benefits and longevity of saunas. In this article, we delve deep into why Thermowood is a better choice than Cedar for constructing outdoor saunas, providing insights based on expertise, experience, and scientific considerations.

Understanding Thermowood

Thermowood is a modified wood produced through a specialized heat treatment process, enhancing its durability and resistance to decay. This innovative wood type has gained popularity for its minimal maintenance requirements and exceptional performance in outdoor environments, making it a preferred choice for sauna enthusiasts seeking a hassle-free experience.

Understanding Cedar Wood

Cedar wood, renowned for its aromatic scent and natural oils, has been a traditional choice for outdoor saunas. Its inherent properties offer resistance to insects and decay, contributing to its widespread use. However, when compared to Thermowood, Cedar has its limitations, especially in terms of maintenance and environmental impact.  In comparison with Cedar, Thermowood is 25% more thermally efficient, thus better suited to sauna.

Durability and Longevity

Thermowood boasts superior durability, withstanding the test of time and elements. Its enhanced lifespan makes it a cost-effective solution, outperforming Cedar, which, despite its resilience, requires more frequent replacements.

Resistance to Decay

The heat treatment of Thermowood elevates its resistance to decay and rot, ensuring a longer-lasting sauna experience. In contrast, Cedar, although resistant to decay, may succumb to environmental factors over time.

Maintenance Requirements

Thermowood’s minimal maintenance needs are a boon for sauna owners. Its stability and resistance to warping reduce the need for regular upkeep. Cedar, with its susceptibility to moisture and temperature changes, demands more attention and care.

Environmental Impact

Thermowood’s production process is environmentally friendly, utilizing less energy and producing fewer emissions. Cedar’s harvesting and processing, on the other hand, have a more significant environmental footprint, raising concerns about sustainability.

Cost and Availability

While Thermowood may have a higher initial cost, its longevity and low maintenance make it a worthwhile investment. Cedar, being more readily available, may be less expensive initially but incurs additional costs in the long run due to maintenance and replacements.

Aesthetic Appeal

Both woods offer distinct aesthetic appeal, with Thermowood presenting a refined and contemporary look, and Cedar providing a classic and timeless appearance. The choice between the two ultimately depends on individual preferences and desired aesthetics.
