In Georgia, where the climate can vary from hot summers to moderately cold winters, choosing the right materials for an outdoor sauna is crucial for ensuring both heat resistance and durability.
When it comes to heat resistance, materials like cedar wood stand out. Cedar has natural properties that make it highly resistant to heat. It can withstand the high temperatures generated inside a sauna without warping or deteriorating quickly. The oils present in cedar also help repel moisture, which is essential as outdoor saunas are exposed to the elements.
Another excellent material option is hemlock. Hemlock is known for its durability and ability to handle heat well. It has a tight grain structure that resists cracking and splitting, even when exposed to extreme temperatures over time.
For the roof and exterior of the sauna, metal roofing materials such as stainless steel or aluminum can provide excellent heat resistance. These metals reflect sunlight and heat, keeping the sauna cooler on the outside while maintaining the desired heat inside. They are also highly durable and can withstand rain, snow, and wind without rusting or corroding.
In terms of insulation, materials like rock wool or glass wool are ideal. They not only provide excellent thermal insulation but also resist moisture and mold growth. This helps maintain a consistent temperature inside the sauna and prolongs the life of the structure.
Finally, for the benches and interior surfaces, heat-treated ash or oak can be a great choice. These woods are durable and can handle the heat from users sitting on them. They also have a beautiful appearance that adds to the aesthetic appeal of the sauna.
