What does faced and unfaced insulation mean? What is the difference between unfaced and Kraft-faced insulation and how is it installed?
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.
Is faced insulation better than Unfaced?
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
.

What is unfaced insulation used for?
Is it OK to use faced insulation in attic?
Do you need to put plastic over faced insulation?
No, you should not do this
. As mentioned above, faced insulation that has a vapor barrier can easily trap moisture. If you put another faced insulation on top of face insulation, a significant amount of moisture can form inside your insulation and in your walls to damage them.
Do I need faced or unfaced insulation in my attic?
Faced Insulation:
If the attic doesn’t have any existing insulation, use faced insulation with the paper facing toward the heated living space
. Unfaced Insulation: When adding more insulation to an attic that already has insulation, use unfaced insulation.
Which side of insulation faces out?
The first layer should have the facing against the drywall to act as a vapor barrier. (The general rule for insulation is that the facing always goes toward the conditioned space.)
The second layer of insulation should be unfaced
so that moisture doesn’t collect between the layers.
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.
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
.

What insulation fits in 2×4 walls?
Insulation for 2×4 Walls
In most wall applications, you will use
R-13 or R-15 kraft-faced fiberglass insulation rolls
for these two-by-four stud walls. While rated differently, these two types of insulation are close enough in thickness that they can both fit into modern two-by-four wall systems.
What is the best type of insulation for an attic?
Spray foam
offers the best attic insulation performance available. Choose from two types: closed-cell and open-cell, aka 2-pound and 1⁄2-pound, respectively. They sport insulation values of approximately R-6.5 and R-3.6 per inch, respectively.
Do you need a vapor barrier with unfaced insulation?
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.
What kind of insulation do I need for my attic?
Fiberglass, cotton, and mineral wool
can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts insulation, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.
Why is there plastic behind my drywall?
Do you tape kraft faced insulation?
Can you put vapor barrier on both sides of insulation?
Can you put too much insulation in attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold
. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
Why is attic insulation Unfaced?
What is the purpose of paper backing on insulation?
The Purpose of Insulation Facing
The paper
creates a vapor barrier that helps keep the water vapor in the warm, moist, heated indoor air from migrating outward into the wall or other structure
. For this reason, faced insulation is typically installed on the “warm in winter” side of the wall.
What happens if you install insulation backwards?
What is the correct way to install faced insulation?
When installing insulation Where is the paper?

Does insulation go behind wiring?
Can you staple unfaced insulation?
