What is Pressure Treated Wood?
Pressure treated wood undergoes a special process where preservatives are infused into the wood under high pressure. This treatment protects the wood from environmental threats like moisture, insects, and decay. Common types of pressure-treated wood include pine and fir, often used in outdoor structures like decks and fences.
However, it’s essential to note that this treatment process can introduce chemicals into the wood. These chemicals are designed to extend the wood’s lifespan but may not be ideal for environments where heat and moisture are prevalent, such as a sauna.
Health Considerations in Using Pressure Treated Wood
One of the main concerns with using pressure treated wood indoors, particularly in a sauna, is the potential release of harmful chemicals. Many pressure treated woods are treated with chromated copper arsenate (CCA), which contains arsenic. This compound can leach out when exposed to high temperatures and humidity, posing health risks.
While newer treatments, like alkaline copper quaternary (ACQ) and copper azole (CA), are less toxic, they still contain copper, which could corrode metal fittings in a sauna. Therefore, it’s crucial to consider the type of treatment used on the wood and the specific environment of your sauna.
Best Practices for Using Wood in Your Sauna
If you decide to proceed with pressure treated wood, follow these best practices:
- Seal the Wood: Use a non-toxic wood sealant to cover the wood before installation. This helps minimize the release of chemicals.
- Ventilation: Ensure the sauna is well-ventilated. Proper airflow can help disperse any potential harmful fumes.
- Limit Exposure: Consider using pressure treated wood only in areas where it won’t be in direct contact with skin or high heat.
- Monitor Conditions: Regularly check the wood for signs of wear or degradation, as the sauna environment can be harsh.
Alternatives to Pressure Treated Wood
If you’re concerned about using pressure treated wood in your sauna, consider these alternatives:
- Cedar: Known for its natural resistance to moisture and insects, cedar is an excellent choice for saunas. It also has a pleasant aroma.
- Redwood: Another natural option, redwood offers similar benefits and is aesthetically pleasing.
- Thermally modified wood: This wood is treated with heat, enhancing its durability without harmful chemicals.
Using these alternatives can reduce health risks and maintain the integrity of your sauna.
