Crawl Space Vapor Barrier
The Problem with Unsealed Crawl Spaces in America
Crawl space vents were designed to allow air to circulate inthe area, in an attempt to prevent moisture and related problems. Over time, builders realized that not only they were inneficient in solving these problems, but they were actually the source of the vast majority of the common problems found in crawl spaces, including:
- Foul, musty odors
- Mold, dry rot and structural damage
- Bouncy or sagging floors
- Impaired air quality
- Uneven and uncomfortable temperatures
- Cold floors during the winter
- Higher utility bills
Crawl Spaces and Energy Efficiency
According to the most recent findings in building science, vented and unsealed crawl spaces are a significant source of energy waste and high heating and cooling bills. According to Advanced Energy, energy losses through the crawl space are so substantial, that you might as well forfeit any other energy-efficient home improvements until you fix the crawl space.
Energy waste is even higher for crawl spaces housing HVAC ducts. During the winter the hote air in the ducts loses temperature as it passes through the freezing cold crawl space. In the summer, it is the cool air that gains temperature as it passes through the hot and humid crawl space. That means that your heating and cooling systems are working much harder than they should, year round, just to keep your home comfortable
Homeowners with encapsulated crawl spaces not ontly experience a healthier and more comfortable home, but they also save an average of 30% in energy bills.
Crawl Space Encapsulation
Encapsulation is. to date, the only science-backed way to treat crawl spaces. The process involves lining and sealing the entire area with a heavy-duty polyethylene barrier. This method creates a dry buffer between the dirt floor of the crawl space, its walls, and the floor above, essentially sealing off the area from external air and moisture. As an added benefit, crawl space encapsulation improves energy efficiency by preventing heat loss and can improve indoor air quality by blocking the circulation of mold spores and other pollutants. A properly encapsulated crawl space has a lifespan of 15 to 20 years or more and pays for itself in energy savings alone.
