What is a Vapor Barrier?

A vapor barrier is simply a type of material used to prevent airflow into a structure. It's used to keep airflow from going through walls, floors, and ceiling in order to keep the water vapor from entering these areas and creating condensation.

This is exactly why a vapor barrier is such an important product. It keeps water vapor outside of walls, ceilings, and floors, where it can cause permanent damages and huge problems.

The main reasons to install a vapor barrier are simply to protect the envelope of a structure from condensation damage, to prevent airflow through the building envelope, and to keep the interior humidity levels under control. It can be a very popular product for many types of building projects.

Installing a Vapor Barrier

Condensation happens when warm air becomes cold and it creates condensation. This means the vapor barrier will be installed on the warmer side of the insulation inside the structure. If it's not installed correctly, it can actually trap moisture in the insulation, which can cause mold, mildew, and other issues.

If you're a DIYer, make sure you handle the installation properly. Contractors will be able to help if you're not sure how to properly install your vapor barrier.
