Crawl Space Vapor Barriers Keep Out Moisture

Out of sight, out of mind. But out of sight doesn’t necessarily mean that excess moisture and poor air quality in your crawl space isn’t hurting you.

Excess moisture supports the growth of mold, dust mites, insects, and other pests.

It also may cause structural damage to your home’s wood framing and degrades some forms of insulation, fiberglass in particular. Poor quality air and allergens caused from mold spores and dust mite droppings (the two largest indoor allergens) can affect some people’s health.

A vapor barrier slows or prevents the evaporation of ground moisture into the crawl space 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.

A vapor barrier, by its nature, resists the passage of air. By stopping air movement from the ground, it can also turn your crawlspace into a semi-conditioned space – one that is close to the temperature of the living spaces above. When that occurs, your floors feel warmer in winter and your energy bills go down.

A vapor/air barrier can also slow or block most of the movement of harmful gases, such as radon, from the soil. Coupled with a radon mitigation system (in the event that radon is present in higher than acceptable levels), a vapor barrier can significantly reduce radon levels in the home.
