A vapor barrier is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings to prevent interstitial condensation and of packaging. Technically, many of these materials are only vapor retarders as they have varying degrees of permeability.
Vapor barriers are generally not needed in climates where the temperature is normally above freezing. Having a vapor barrier is not a negative it is just unnecessary. Foam insulations and dense-packed cellulose are desirable because they act as a both a water vapor and air barrier. If you do install a Kraft paper-faced fiber insulation batt, discussion which way to face the paper (to the inside or outside) with your local building department. Podcast: Play in new window Tom: “It sounds odd, but the answer is yes if you’re going to use a paper backed insulation in the wall.I used to do this.

These barriers are required where there is cladding on the house that doesn't allow enough drying to the outside. Type 2 vapor barriers, the basic vapor barrier for ordinary conditions, are defined as having a permeance less than or equal to 60 ng/(Pa·s·m 2) of moisture passage. Prevalent vapor barrier materials used over the years have been polyethylene (Type 1), asphalt-impregnated or asphalt-coated kraft paper (Type 2) and foil skrim kraft (FSK) (Type 1) - paper-backed aluminum. Vapor barriers are sheets of plastic or other material placed on one side of insulation sheets. This barrier is meant to keep moisture from getting to the insulation in the walls and ceilings, and it is required by building codes when insulating most houses. In any case, the vapor barrier must point to the warm side.
Unfaced means the insulation lacks a vapor retarder (paper or plastic facing). Kraft-faced insulation includes a paper vapor retarder, which helps prevent mold
If we are going to still accept fiberglass insulation is unfaced with poly a better choice. 2014-04-02 Because insulation is added to existing homes in nearly all cases without a vapor barrier, major questions have increasingly been raised regarding the possible effects of moisture migration through walls on the thermal performance of the insulation and on moisture damage in the wall structure.
