What Type of Vapor Barrier Should Be Used For My Crawl Space?

Wondering what type of crawl space vapor barrier to use? Let the crawl space encapsulation experts at '58 get the job done right!

Best Crawl Space Vapor Barriers

Does your crawl space get wet, damp, or musty? There’s a good chance that your crawl space is experiencing moisture problems. Originally, crawl spaces were designed with the purpose of protecting your living space from the moisture in the soil. Crawl spaces can become traps for water and moisture, which can lead to moisture-related problems in your crawl space and potentially your home. But with help of a crawl space vapor barrier, your crawl space can have a protective shield against invasive moisture.

But what kind of vapor barrier should you have your crawl space sealed with? Your local crawl space encapsulation experts at ’58 can help answer that!

Not All Crawl Space Vapor Barriers Are Made Equal

There are several types of vapor barriers and even then they can range in varying thicknesses as well. These types are categorizes as Class 1, Class 2, and Class 3 vapor barriers.

  • Class 1 Vapor Barriers measure at 0.1 perm or less.
  • Class 2 Vapor Barriers measure at 1.0 perm or less but greater than 0.1 perm.
  • Class 3 Vapor Barriers measure at 10 perm or less but greater than 1.0 perm.

Perm describes a crawl space vapor barrier’s measurement of water vapor permanence. The lower the perm, the better the vapor barrier is at keeping moisture from getting through.

Also, it is important to make sure your vapor barrier is thick enough to withstand wear-and-tear. A torn vapor barrier in a crawl space is like not having a vapor barrier at all.

Some homeowners opt to try encapsulating their own crawl space with a store-bought vapor barrier. But these vapor barriers often are either not thick enough and tear easily, or they don’t offer the proper perm rating to protect their crawl space from moisture.

An experienced local crawl space encapsulation contractor like ‘58 Foundations & Waterproofing can help seal your crawl space and keep that troublesome moisture out. Our vapor barriers not only help keep moisture out, but they are tough and thick.

With a local crawl space encapsulation system from ’58, your crawl space will be more than just safe and dry, you can turn that extra space into anything you desire!
