Insulation in rolls, called batts, comes in two varieties: faced and unfaced. Faced, or the type with paper, is typically used in first-time applications, such as in walls, ceilings, floors, and in crawl spaces. Any time you use a faced insulation, the paper needs to be facing toward the living space. So in an attic the paper faces downward and in a crawl space, it faces upward. Unfaced insulation—the type without paper—is what you would use if you are adding insulation to your attic or to place between floors when living space is above and below. Unfaced is also your best choice for adding soundproofing to interior walls. We want to hear from you!

Unfaced means the insulation lacks a vapor retarder paper or plastic facing. Kraft-faced insulation includes a paper vapor retarder, which helps prevent mold and mildew. Kraft-faced insulation should be installed in exterior walls, exterior basement walls, and attic ceilings by pressing the product into the wall cavity with the paper side facing outward, towards the installer. The insulation should be snug in the cavity, but not compressed. If the product needs additional support, consider using a staple gun to hold the insulation in place.

Faced insulation is a type of blanket insulation that is typically made of fiberglass. It differs from unfaced insulation only in that it has a vapor barrier also called vapor retarder that blocks moisture from moving from one space to another. The vapor barrier is usually made of kraft paper. Faced insulation is sold in rolls or batts that are stapled to joists or beams. The choice between faced and unfaced installation usually comes down to climate. However, some people in climates where faced insulation is required or recommended choose to buy unfaced and then pair it with a material such as plastic sheeting to form a makeshift vapor barrier.

Faced or Unfaced Insulation: What are the Differences?

Air migrates from warmer spaces toward colder spaces, and insulation is designed to help prevent or at least slow that migration. Facing is a thin layer of paper or plastic attached to one side of batting insulation, which is sold in a roll. Whether you choose faced or unfaced insulation for the attic depends on the application and whether some insulation already is present. As a result of evaporation, people breathing and plant respiration, air carries some moisture with it. Should those water droplets get caught in the folds of insulation, it could lead to mold or mildew.

Unfaced vs. Kraft-Faced

Literally made of spun glass, fiberglass insulation was originally something of an accident. In a researcher was trying to seal two glass blocks together with a vacuum seal when a blast of high-pressure air produced a mass of fine fibers from the molten glass. Eventually, a refined version provided material for clothing, boats, fishing poles, car parts and home insulation. Today, fiberglass insulation in any form -- pink, yellow, green or white, faced or unfaced, rolls or batts -- remains an effective and popular insulator. Each inch of thickness delivers a thermal resistance value of approximately R
