Do you need to put plastic over faced insulation? More than likely, installing an additional layer of poly over kraft facing won’t cause any problems — it’s no more risky than if the wall had only unfaced batts and poly — and the risk of using poly on the interior is relatively low in a cold climate like New York’s.
Do you need vapor barrier over faced insulation? Vapor barriers applied over the face of the insulation provide additional benefits in the fight against moisture. Usually composed of a thin film, such as polyethylene, vapor barriers are used to retard or prevent water vapor diffusion into a wall, ceiling or floor during the cold winter.
Does faced insulation need plastic? In most climates, it needs a vapor barrier. Some builders rely on batts with attached kraft-paper facing to do that job, but Tom recommends unfaced batts, covered in plastic with all the seams taped shut.
Does faced fiberglass insulation need to be covered? To satisfy building codes, most faced insulation must be covered with half-inch-thick wallboard or other code-approved material to reduce the chances of its igniting during a fire.

Can you patch insulate air ducts?
