Vapor barrier The phrase vapor barrier is often used to refer to any material, typically a plastic or foil sheet, that resists passage of moisture through
Mainly installed in crawlspaces, attics, and basements, a vapor barrier is a heavy-duty material typically made of plastic or foil sheet that helps prevent moisture and water vapor from seeping through walls, ceilings, and floors. Normally, air and water vapor can move freely through building...
If the vapor barrier is on the outside, it prevents the humid air from diffusing into the wall cavity and finding the cold surface on the other side of the cavity, the back side of the drywall. So, like a vapor barrier on the inner surface in cold weather, putting one on the...
A.Moisture control in the walls of a finished basements is tricky, since the vapor drive between the soil and the basement is small and could go either way depending on conditions. The most common practice is to place the vapor barrier below the wall finish as you would with an above-gra...
