Do I need a vapor barrier in my crawl space?
The polyethylene vapor barrier resists the passage of air. Preventing air movement from the ground can turn your crawlspace into a semi-conditioned space close to the temperature of the living spaces above. Your floors feel warmer in winter and your energy bills can go down. A vapor barrier in your crawl space slows or prevents the evaporation of ground moisture into space. If coupled with a waterproofing system, moisture and water can be diverted from the crawl space preventing future problems. Eliminate rot, rust, mold, odors, insects, or other moisture-related issues.
Up to 40 percent of the air on the first floor of our homes comes from the basement or crawl space! Warm air in the upper levels of a home rises and is expelled through the attic that air that’s expelled must be replenished. The vacuum caused by this air movement sucks air up from the crawl space or basement.
