Vapor Barrier

What Is Vapor Barrier?


A vapor barrier is a sheet of material through which water vapor cannot easily pass, such as aluminum foil, polyethylene film or an asphalt-impregnated kraft paper.

While the installation of a crawl space vapor barrier may seem relatively simple, this is a project for a professional insulation contractor because it is much more complicated than it seems. For example, industry standards for vapor barrier installation materials are far superior to the quality of materials from a retail supplier.

These are examples of excessive crawl space moisture problems:

  • Paint peeling from the exterior of the home
  • Standing water or mud conditions on a dirt floor following heavy rains
  • Indications of rust and rot in the crawl space
  • Mold and mildew on first-floor walls
  • High radon levels
