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 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
*This client requested a clear vapor barrier.
Most homes in Middle Tennessee come with a thin vapor barrier covering the dirt floor. Over time, the vapor barrier deteriorates due to water infiltration and damage caused by insects, pests, and other repairs to the home.
If you are experiencing more severe water or humidity concerns, we recommend installing a full encapsulation. T.H.E. installs a 12 mil carbon fiber reinforced barrier that completely seals off the crawl space. A dehumidifier works in conjunction to regulate the humidity and circulate air. This is considered an upgrade to the more basic vapor barrier.
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.
If you are having problems in your crawl space, let T.H.E. Construction inspect, diagnose, and find the right crawl space solution to fit your home for the health and the safety of your family.
