Can I use unfaced insulation in ceiling?
Faced, or the type with paper, is typically used in first-time applications, such as in walls, ceilings, floors, and in crawl spaces.
Unfaced insulation—the type without paper—is what you would use if you are adding insulation to your attic or to place between floors when living space is above and below..
What are the 3 types of insulation?
The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool. All of these materials are produced using recycled waste materials. Cellulose is primarily made from recycled newsprint. Most fiberglass products contain 40% to 60% recycled glass.
Should I use faced or unfaced insulation in my basement ceiling?
Faced insulation — insulation with a paper covering — is suitable for use when you’re insulating the ceiling of a basement that you’re not planning on finishing. … In cases where the insulation will be covered with suspended or drywall ceiling, unfaced insulation is entirely suitable.
Is it bad to insulate basement ceiling?
Insulating the basement ceiling will keep most of the heat upstairs in the living space. As a result, the basement will be colder in the winter making it important to also insulate any water pipes or heating/cooling ducts in the basement.
Is it OK to insulate roof rafters?
Insulating between rafters will do no good, because the attic should be ventilated, and the rafter insulation would be between two unheated spaces. … Moisture buildup in the attic is a concern because it can condense into water, often causing mold. Good ventilation, from soffit vents and a ridge vent, will stop that.
How do you insulate a ceiling without removing the drywall?
The easiest place to add insulation without affecting drywall is in an attic, under the roof. That also is where added insulation is most beneficial. One option is to add loose fill insulation such as cellulose, rock wool or fiberglass beads. These insulations are available in bags at building supply stores.
Is it better to insulate ceiling or roof?
Saving energy costs by preventing heat loss due to heat conduction. Preventing the roof from accumulating moisture damage. Ease of construction- insulating the ceiling can be easier than insulating the roof, particularly with older homes.
Should you insulate interior ceilings?
In addition to walls and attics, insulation should be installed in ceilings with unheated spaces, basement walls, floors above vented crawl spaces, cathedral ceilings, floors over unheated garages or porches, knee walls, and in between interior walls—especially bathrooms—as well as ceilings and floors.
Should I use faced or unfaced insulation in crawl space?
In crawl spaces, unfaced insulation is generally only used when adding to existing insulation. It’s important not to lay faced insulation on top of faced insulation.
How do you insulate a wood ceiling?
There are two safe ways to improve the situation: Add more insulation underneath the existing ceiling wood, then install a vapor retarder (retarder, not barrier. A smart membrane, not poly sheeting), then cover that up with drywall.

Can you over insulate an attic?
But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality.
What insulation should I use in my ceiling?
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
Does it matter which way insulation faces?
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.
What is the most effective roof insulation?
The most common form of loft insulation, this comes in rolls of rock, glass or mineral fibre (we use Earthwool by Knauf which is a really good environmentally friendly option), or else foil-backed felt. It’s generally the cheapest option and good all-purpose insulation, especially for between joists.
Are interior walls typically insulated?
Insulating interior walls isn’t as common, although it offers homeowners some energy saving and sound-dampening benefits. The best time to insulate all walls is during new construction, but it’s possible to add insulation to existing walls without tearing off the drywall.
Can you over insulate a house?
It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That’s when mold starts to grow.
