What is crawl space encapsulation?

Crawl space encapsulation is a generic term used to describe a crawl space that is protected from moisture by using a crawl space vapor barrier on the floor and walls. There are different ways to accomplish this, as well as different results, depending on the "system" you purchase. If you hire a company or franchise to finish your crawl space make sure you get the most for your money. Crawl space encapsulation alone will help reduce moisture and improve the environment of the crawl space, but there are other components to consider like; the quality of the crawl space vapor barrier, how to close the foundation vents permanently, crawl space insulation, sealing the crawl space vapor barrier to the foundation wall, conditioning the crawl space, crawl space moisture control and lowering the homes energy costs.
