Can I remove the paper backing on insulation?
Luckily, the Kraft paper facing is easy to remove. Simply pull on the facing with one hand and use the other hand to push the batt or roll away from the facing. Then, you’ll be able to proceed with the repair.
Do you leave the paper on insulation?
As you add the insulation, keep the paper backing facing down toward the room below. Avoid compressing the batting because diminishing its loft also diminishes its ability to prevent warm air from migrating out of the heated space below.
What is the purpose of the paper 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.
Does the paper go inside or outside on insulation?
Regardless of whether fiberglass insulation is installed in a wall, attic, or crawlspace; the paper facing should always face toward the inside of the home. That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it.
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.
Does faced insulation need to be covered?
To satisfy building codes, most faced insulation must be covered with half-inch-thick wallboard or other code-approved material to reduce the chances of its igniting during a fire. There is a type of faced insulation approved for exposed installations.

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.
How do you cover unfaced insulation?
Cover the newly installed insulation with a layer of plastic sheeting or other vapor barrier only if there isn’t already a vapor barrier in place. If the insulation is installed over existing insulation, either faced or with a barrier over top, adding another vapor barrier will lead to structural problems.
Which side of insulation board faces out?
The reflective side of the board should be oriented to the exterior and the non- reflective white side should be oriented to the interior. EXCEPTION: If vinyl siding is to be installed over AP™ Foil- Faced sheathing, install foam boards with the white nonreflective side toward the vinyl siding.
Can you put Poly over kraft faced insulation?
More than likely, installing an additional layer of poly over kraft facing won’t cause any problems — it’s no more risky than if the wall had only unfaced batts and poly — and the risk of using poly on the interior is relatively low in a cold climate like New York’s.
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.
