Common facing materials include kraft paper, white vinyl sheeting, and aluminum foil. All of these materials act as an air barrier and vapor barrier. Aluminum foil can also act as a radiant barrier. Your climate and where and how you're installing the insulation in your home will determine what type of facing and/or barrier, if any, you'll need.
Some of the same materials used as insulation facings can be installed separately, bordering the insulation to provide an air barrier, vapor barrier, and/or radiant barrier.
