Learn the difference between faced vs unfaced insulation to help determine which option is best suited for your home. Bob Vila explains.
Faced Insulation is fiberglass insulation with a kraft paper vapor barrier on one side. It’s stapled into place with the paper side facing the interior of the home. Unfaced insulation has no kraft paper vapor barrier attached to it and is held into place by pressure or friction.
Faced insulation should be used to insulate the roof of the attic while unfaced insulation can be used to insulate the attic floor. Correctly installing both faced and unfaced installation in the attic will increase the energy efficiency of the home.

The key difference between the two is that unfaced insulation provides basic insulation and faced insulation protects from moisture. Whether it be the differences in function or installation, follow along as we compare faced and unfaced insulation.
Unfaced insulation is made of the same materials as faced insulation but without the facing/barrier. Unfaced insulation is most commonly employed in areas where vapor barriers are not necessary, or where separate vapor barriers will be used.
While unfaced insulation is pretty straightforward‒ insulation without any added retardant layer, often spray foam or loose-fill fiberglass‒ faced insulation comes in several types, and each has a benefit for your home.
The main difference between faced and unfaced insulation is that faced insulation has an additional moisture barrier, called a face, while unfaced does not. This additional barrier makes a large difference in moisture retention with a minimal increase in cost.
One of the main differences between faced and unfaced insulation is the presence of a paper vapor barrier. Faced insulation has this barrier attached to the insulation to block moisture from getting into the insulation and, ultimately, the walls and ceilings of your home.
Unfaced insulation is non-combustible – it can help slow flame spread and prevent fire. You can use unfaced insulation anywhere that requires a barrier between warm and cold areas, such as exterior walls, crawl spaces, vaulted roofs, and attic floors.
