Is it better to use faced or unfaced insulation?

The Difference Between Faced And Unfaced Insulation



Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn’t fall down as much. Unfaced insulation is just as good as faced, but it doesn’t have that paper attached to it.

Does it matter if insulation is faced?





To be effective, the barrier’s reflective surface must always face an air space at least an inch thick and be installed shiny side up if laid on the attic floor, shiny side down if attached to the rafters. Tests show that a radiant barrier in an insulated attic can lower attic temperatures by as much as 30 degrees.

Where do you put faced insulation?

For this reason, faced insulation is typically installed on the “warm in winter” side of the wall. In other words, the facing usually faces in toward the living space (or into the attic or basement area, in unfinished attics and basements).

Faced insulation is slightly more expensive.



There is a minor cost difference between faced and unfaced insulation. On average, faced insulation costs about $0.50 to $2 per square foot of wall or ceiling. Unfaced insulation costs about $0.50 to $1.75 per square foot.

When should I use unfaced insulation?

Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces. It’s best used for interior wall applications that do not face the outside and also in rooms that don’t need moisture control, like living rooms, dining rooms and studies.

Do I need a vapor barrier if I use faced insulation?





Since vapor barriers are only additional protection and not required to finish faced insulation, they are not always necessary. In fact, in some parts of the United States, it is better to not add vapor barriers as they can do more damage than good to your insulation.

Does faced insulation need to be stapled?

INSTALLING FACED INSULATION WITHOUT USING STAPLES



Make sure the insulation facing is flush with the face of the stud. The insulation must fit snugly at the sides and ends. Some CertainTeed products, such as SpeedyR, are prodcuced without stapling flanges specifically to be friction fit, and do not need to be stapled.

Should you put plastic over insulation before drywall?

Without poly beneath the drywall, water vapor hits the drywall and diffuses through to the drier (in summer) indoor air. By installing a sheet of poly there, you cut off that drying mechanism and water that finds its way into walls can stay there longer and do more damage.

Can you put unfaced insulation over faced insulation?

No, faced insulation should not be added over existing insulation since the vapor retarder on top of or between layers of insulation can trap moisture. Let Accurate Insulation handle your home insulation project from start to finish.

Do you use faced insulation in interior walls?



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.
