Vapor Barrier

In your crawl space, you must install a vapor barrier. Furthermore, a moisture barrier is the bare minimum of protection that you should have installed in your crawl space to keep it safe. It is possible to save money by installing a vapor barrier.

Is crawl space encapsulation same as installing a vapor barrier?

Vapor barriers and encapsulation are distinct in that they both completely seal out water vapor while also interrupting the process of water vapor moving upward from the ground up. Because the entire crawl space, including the walls, is encapsulated, the likelihood of developing moisture problems as a result of water vapor is reduced to virtually zero.

Why should you not encapsulate crawl spaces?

Mold, mildew, and other contaminants can be introduced into your home through an unencapsulated crawl space. In addition to making your indoor space uncomfortably hot and stuffy to be in, contaminated air may also be hazardous to your health. It is possible to stop this problem in its tracks once the crawl space has been sealed.

Is it really worth it to enclose your crawlspace?

In addition to improving air quality in your home, crawl space encapsulation can also help you save money on energy costs and protect your home from structural damage. A layer of plastic and a dehumidifier can both help to prevent moisture from accumulating in the enclosed space and the growth of mold and mildew.

Are vapor barriers for crawl spaces effective?

Plastic vapor barriers will prevent the majority of water vapor from seeping up from the soil and into your crawlspace, but increasing cross ventilation through the crawlspace is an important additional method for preventing any residual moisture from becoming trapped in the space and causing mold growth.

What is the best way to install a vapor barrier in a crawlspace?

experts recommend that the plastic be secured about six inches up the wall from the ground. In order to keep it protected from potential future disturbances, use landscape fabric stakes. There’s a good chance that someone will have to slide around in the crawlspace later to fix a pipe or run a new cable in the basement.
