A crawl space vapor barrier is the foundation of every crawl space encapsulation system. It prevents ground moisture from rising into your home, protecting structural wood, insulation, and indoor air quality. Crawlspace Depot carries vapor barriers in a wide range of thicknesses and construction types, from lightweight non-reinforced poly to heavy-duty 20 mil reinforced and woven-coated rolls, so you can match the right product to your crawl space conditions.
