Kraft-faced insulation has an asphalt-backed kraft paper attached to one side of the insulation. The asphalt on the kraft paper acts as a vapor retarder which helps with moisture migration. Because kraft-faced insulation is paper faced, it does not have a fire rating and should not be left exposed.
Kraft or foil facedFaced insulation is a batt or roll of fiberglass insulation with an attached kraft paper or foil facing. Kraft and standard foil facings can burn and must not be left exposed. If an exposed application is required, use FSK-25 flame-resistant faced insulation.
No, if the facing is installed per instructions and the facing remains unbroken with only minor gaps around electrical boxes, etc. Any tears or large gaps should be repaired with high quality waterproof tape. In fact installing plastic sheeting over the facing can result in trapping moisture between the two layers.
Faced insulation will have some covering, such as foil or paper. Without that “face,” it will be challenging to apply tape. When the facing side of insulation goes against the actual bay of the attic or crawlspace, then there is no need to tape it because you cannot reach it.
You should always install a vapor barrier to protect exposed ceiling insulation even if it's temporary. Consult with a building or safety expert to confirm where else in the structure a vapor barrier may be required.
Faced insulation, also known as "kraft-faced insulation," is fiberglass insulation with a vapor barrier or vapor retarder. This prevents moisture build-up on the walls and ceilings of your home, especially during humid temperatures.
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.
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.
ECOCELL Blankets can be left exposed or even painted. Unlike other insulation materials, ECOCELL does not have to be covered with gypsum board. Leaving ECOCELL exposed is another reason ECOCELL is the cost effective solution for insulating basements and crawlspaces.
Exposed insulation can irritate your skin, eyes, and lungs. It can also be a fire hazard, especially in areas like the attic, basement, or garage. Plus, it can lead to mold and mildew growth, which can cause even more health issues.
Kraft facing should never be left exposed. Products are largely made of newspaper, which is highly combustible. Even though it's heavily treated with fire-retardant chemicals prior to installation, it is a recognized fire hazard by the Consumer Product Safety Commission (CPSC).
Is the kraft facing a vapor barrier or not? It depends on the time of year. If the facing is installed towards the interior in a climate such as Washington, D.C., it is a vapor barrier in the winter and a vapor retarder in the summer.
Any new batt or roll insulation added on top of existing insulation in the attic needs to be without a vapor retarder (face). Most vapor retarders on fiberglass are made of kraft paper. The presence of this paper vapor retarder on top of between layers of insulation can trap moisture leading to mold or even rotting.
In general, the color of insulation doesn't equal better performance over another color. Whether it's pink, white, brown, or yellow—color doesn't influence dependability, reliability, or the products effectiveness.
Cut the insulation to fit as necessary. Leave the pieces about 1 inch larger than the cavity to fill the space completely. Staple the flanges of faced insulation to the interior faces of the wall studs or stud edges.
AP™ Foil-Faced insulation must be covered with an approved thermal barrier and cannot be left exposed.
When fiberglass batts are compressed, both the thickness and the R-value go down. The deeper the cavity, the more the R-value is reduced. 14 inch R-49 insulation is reduced to R-44 when compressed to fit an 11 ⅞ inch space. Further compression of 5/8 of an inch (11 ¼ inches) reduces the R-value to R-42.
Most types of insulation come as faced. 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.
Different parts of the house demand different insulation materials. For example, faced insulation is better used on exterior walls, attic ceilings, basements, and bathrooms, while unfaced one is commonly used on interior walls, crawl spaces, or between floors.
Kraft-faced insulation includes a vapor retarder which helps with moisture migration from unconditioned outside air. Install kraft-faced batts with the paper facing toward the inside of the home. Get more tips on installing EcoBatt insulation: https: //bit.ly/3oH8uOC.
If you're using faced insulation, install it with the vapor retarder positioned down toward the room. Hold the insulation up with one hand, while stapling the flange on both sides every 6" - 8" with the other hand.
Faced Insulation
This is especially important for areas that are prone to condensation or moisture accumulation, such as attics or walls near bathrooms or kitchens. The vapor retarder helps keep moisture from becoming trapped in the walls and ceiling, ensuring that your home stays dry and comfortable.
