PROS AND CONS ON WHY CRAWLSPACE VAPOR BARRIER IS EFFICIENT
Moisture is one of the main enemies of a home’s structure, potentially causing both structural problems and health issues. Uncontrolled moisture can cause rot and decay in wood framing and other materials, and it fosters mold and mildew that can cause allergies and asthma. At its most extreme, moisture can even determine if the construction of a home or room addition is possible at all. Where moisture is a known problem, vapor barriers are integrated into wall, ceiling, and floor construction to combat it effects. But nowhere is moisture more damaging than in a crawl space, even though it is not seen.
The crawl space has direct contact with the ground, it should be no surprise that moisture will develop here. It is difficult to overstate the problems that can occur because of crawl space moisture. One of the most serious problems caused by moisture is mold, mildew, and other fungi.
A vapor barrier slows or prevents the evaporation of ground moisture into the crawlspace air. If coupled with a waterproofing system, moisture and water can be expelled from the crawl space before it can cause problems. No more rot, rust, mold, odors, insects, or other moisture-related problems.
