Are Radiant Health Saunas Zero VOC?
Radiant Health saunas are certified Zero VOC, giving you confidence that the air inside your sauna remains clean and free from volatile organic compound (VOC) emissions. In this article, you'll learn what VOCs are, why they matter in a heated environment, and how our materials and construction help achieve our Zero VOC certification.
What Are VOCs?
Volatile Organic Compounds (VOCs) are chemicals that can be released into the air from certain materials, including some woods, adhesives, paints, finishes, and other manufactured products. Because infrared saunas operate at elevated temperatures, many customers want to know whether the materials used inside the sauna could contribute to unwanted emissions over time.
Radiant Health addresses this concern by carefully selecting materials that support a clean sauna environment and by verifying their performance through independent testing.
How Radiant Health Achieves Zero VOC Certification
Every material used in a Radiant Health sauna is selected with indoor air quality in mind. From the wood and finishes to the heater system and adhesives, each component is chosen to help maintain a clean sauna environment while delivering long-lasting performance.
Unfinished Canadian Hemlock Interior
The interior of every Radiant Health sauna is crafted from premium furniture-grade Canadian hemlock that has been kiln-dried to 6–8% moisture content for exceptional durability and dimensional stability.
Unlike many wood products, the interior surfaces are left completely unfinished, with no stains, paints, lacquers, or chemical coatings applied. This preserves the natural beauty of the wood while supporting our Zero VOC certification.
Water-Based Exterior Finish
To protect the exterior of the sauna without affecting the interior environment, exterior wood surfaces receive a clear, water-based finish that enhances durability while maintaining the natural appearance of the wood.
Carefully Selected Components
Every component inside the sauna is chosen with the same attention to air quality.
This includes:
- Heat-resistant nylon-blend heater fabric designed for long-term performance.
- A metal-composite floor system tested under heated operating conditions.
- Minimal use of non-toxic, water-based adhesives where required during manufacturing.
Together, these carefully selected materials help support Radiant Health's Zero VOC certification.
Independent Testing & Certification
Radiant Health saunas conform to the French A+ indoor air quality standard, one of the world's most rigorous emissions certifications for interior products.
Unlike certifications that evaluate only individual materials, French A+ testing measures emissions from the fully assembled product under standardized chamber testing conditions. This provides a more complete picture of the air quality customers can expect during everyday use.
Our Zero VOC certification reflects our commitment to transparency and gives customers confidence that their sauna has been independently evaluated against recognized emissions standards.
Why Zero VOC Matters
Choosing a Zero VOC sauna offers benefits beyond craftsmanship alone.
By carefully selecting materials and independently verifying emissions performance, Radiant Health helps create a sauna environment that is:
- Clean and fresh, even at elevated operating temperatures.
- Free from unwanted chemical odors that can be associated with certain materials.
- Built with carefully selected components that support long-term indoor air quality.
- Independently tested to provide added confidence and peace of mind.
Frequently Asked Questions
What are VOCs?
VOCs (Volatile Organic Compounds) are chemicals that can be released into the air from certain materials such as paints, finishes, adhesives, and manufactured wood products.
Why do VOCs matter in an infrared sauna?
Heat can increase emissions from some materials. That's why choosing materials that have been carefully selected and independently tested is an important part of creating a clean sauna environment.
Why is the interior of the sauna unfinished?
The interior Canadian hemlock is intentionally left free from stains, paints, lacquers, and chemical coatings to preserve the natural wood while supporting our Zero VOC certification.
Are water-based finishes always Zero VOC?
Not necessarily. While water-based finishes generally contain fewer VOCs than many traditional coatings, they are not automatically Zero VOC. That's why Radiant Health carefully selects its materials and verifies the performance of the finished sauna through independent testing.
How can I maintain clean air inside my sauna?
Keep your sauna clean using mild, unscented soap and water on a slightly damp soft cloth, ensure the area is well ventilated, and avoid introducing strongly scented cleaning products or chemicals into the sauna.
