Does vapor barrier go over Kraft faced insulation?
In simple terms, a vapor barrier is a material that won’t allow moisture to pass through it, such as plastic sheeting. There are two basic types of vapor barriers used with exterior wall insulation. The most common is paper-faced insulation. This type of insulation has a Kraft paper face with two flanges.Click to see full…

Likewise, people ask, can you put a vapor barrier over faced insulation?The special paper lining one side of the insulation is sufficient to block moisture and air. Some builders choose to attach a separate vapor barrier even with faced insulation, however. It doesn’t hurt anything. The result, when finished, is a super-insulated wall with a foam vapor barrier instead of sheet plastic.Likewise, does vapor barrier go before or after insulation? In cold climates like Canada, for most of the year the vapor barrier should be on the inside of the insulation. In hot climates like the southern U.S. for example, vapor barrier should be installed on the outside of the insulation, especially where there’s air-conditioning involved to prevent condensation and mold. Just so, does Kraft faced insulation need a vapor barrier? The facing on kraft-faced insulation is made of kraft paper with an asphalt coating that makes the paper impermeable to water vapor. The paper creates a vapor barrier that helps keep the water vapor in the warm, moist, heated indoor air from migrating outward into the wall or other structure.Is foil faced insulation a vapor barrier? Vapor Barrier Fiberglass Insulation Batts Both paper (called kraft paper) and foil faces offer vapor barrier properties. Paper and foil-faced insulation, plus gypsum board and certain latex paints, work well together as a team to stop moisture migration. That’s when foil-faced batts really shine.
