What is a Vapor Barrier?

 

A vapor barrier is a material that we can install on the outside of your home to help keep water vapor from seeping in. Many people are not aware that there is such a thing as a vapor barrier, but it's essential to have one if you want to protect your house from dampness and mold. If you're concerned about moisture in your home and would like more protection, it's a good idea to invest in your very own vapor barrier!

How It Works

Water vapor is continuously evaporating from the ground; even if the crawlspace floor looks dry, this water vapor evaporation is still occurring. A vapor barrier is the most straightforward and cost-effective way to stop this problem. A sound vapor barrier can reduce humidity by 15-30 percent, depending on the installation type.

Traditionally, a vapor barrier was used to cover only the ground floor to prevent water vapor from evaporating from the soil and moving up into the crawlspace air. This water vapor can cause excess humidity levels that also allow water damage, odors, and bugs to become a problem in your crawlspace and upper living spaces. You should only install a vapor barrier after any groundwater problems are corrected.

The Material

A standard and commonly seen vapor barrier is made of 6-mil poly plastic. This is the minimally accepted material allowed by codes such as the International Residential Code. This type of vapor barrier is used when an attic or crawlspace does not have a sidewall water penetration problem. Industry requirements for this type of installation are that the material must cover the entire floor and that seams should overlap 12 inches.
