stack effect

The stack effect is the natural movement of air in your home: warm air rises and escapes through the attic, while cooler air gets pulled up from the crawl space or basement. This airflow pattern can bring moisture, mold spores, and unpleasant odors into your living space—especially if the crawl space isn’t sealed or properly ventilated. Understanding the stack effect is crucial for improving indoor air quality and energy efficiency. ATMOX systems address this by managing both crawl space and attic environments, reducing the moisture and contaminants that enter through air movement. Controlling humidity and temperature in these areas helps reduce the stack effect’s negative impacts. The result? A healthier home with fewer odors, better air quality, and less strain on your HVAC system.
