How Clean Is the Air in Your Home?

The Stack Effect

The way air moves throughout the home is called the "Stack Effect". Warm air moves upward through the home. As air leaves from the upper floors and attic, it pulls from below, including your basement or crawl space. As a result, whatever is in the air, including humidity, will also be in your home. If you have foundation vents in your crawl space, the problem is compounded. Humidity flows into the crawl space from the outside air. This air is then pulled upward into the home to fill the vacuum caused by the stack effect. The end result: The air you breathe inside your home, comes from your crawl space.

Crawl Space Vapor Barriers vs. Encapsulation Systems

Most homes in Middle Tennessee come with a thin vapor barrier covering the dirt floor. Over time, the vapor barriers deteriorate due to water infiltration and damage caused by insects, pests, and other repairs to the home.

Encapsulation vapor barriers are much more durable and designed to seal off moisture to reduce humidity levels. Foundation vents are sealed off and a dehumidification system is installed. This prevents air from moving through your crawl space and upwards into your living space. 

Crawl space and basement dehumidifiers are the key to controlling the relative humidity, mold, rot, dust, and other allergens keeping the air in you home clean and healthy.
