If you’re finishing your attic, insulating it to the proper R-value can cause a dramatic loss of headroom if you limit yourself to fiberglass batts. To maximize headroom, properly insulate your attic and ventilate the roof, use a combination of dense batt insulation, rigid foam sheeting and air chutes.
How do you insulate a bedroom?
The easiest way to re-insulate your walls is to spray foam insulation into the wall cavities. Spray foam insulation expands to fill small gaps and enclosed spaces. You can apply spray foam insulation into each wall cavity through small holes in your wall.

Where should you not put insulation?
Do not use fiberglass insulation in basements. Fiberglass traps mold well and basements are notorious for having moisture problems. Instead, use closed cell foam board and spray for basement installation. Never place insulation close to water heaters, oil burners or anything hot.
What type of insulation is best for attic?
Many people consider fiberglass batt to be the best attic insulation. It consists of plastic reinforced by small glass fibers. The batt version comes in blanket form — i.e., small, pre-cut sections that you can lay down wherever you need to.
Why is my bedroom colder than the rest of the house?
You might have heavy furniture or items covering up your vents, absorbing all the heat. This is a very common reason why one room in a house is always cold, and it’s easily solved by simply moving the items away from your vents, allowing an unobstructed flow of warm or cool air.
Why is my bedroom wall so cold?
Simply put, cold walls are caused by poor insulation. If your home is poorly insulated, it means that heat from inside the home is easily escaping to the outside. Warm air moves from inside the rooms, passing through the walls to be lost outside. Without insulation, there’s no barrier to keep the heat in.
Can you use an attic as a bedroom?
If you’ve converted an attic and want to count it as a bedroom, it has to have at least 70 square feet of space. This is large enough to fit a bed and a small dresser. While a 7 x 10 bedroom is not spacious, it would fit the legal requirements in most locations.
How do I insulate my attic ceiling?
Quote from the video:
Quote from Youtube video: Place the craft faced insulation. Down between the joists on top of the drywall. And with the facing down toward the interior of the house be careful not to compress the insulation.
Can my attic support a floor?
That begs the question; can my attic support a floor? The answer, in most cases, is a definite yes. Even though it wasn’t put there, the joists supporting your ceiling are quite strong. Putting down flooring won’t stress them any more than the floors in your bedroom, kitchen, or bath.
Can you have too much insulation in your 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.
Which is better attic insulation blown or rolled?
Rolled fiberglass insulation scores an R-value of 3.7. So overall, rolled fiberglass insulation is slightly more effective at blocking in and out heat than its blown counterpart.
Should attic insulation be faced or unfaced?
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.
Can you put plastic over insulation in attic?
Plastic isn’t recommended in this situation because it would create a second vapor barrier that can trap moisture and result in condensation and mold. Craft paper would have the same problem, this is what is most likely on the other side of the insulation for the vapor barrier you want.
Is a vapor barrier necessary in attic?
In hot-dry climates a vapor retarder should also not be installed, but attics can be vented. All attics — vented or unvented — should have an air barrier (a properly detailed airtight drywall ceiling, for example) regardless of climate.
Is faced insulation worth it?
It can actually help reduce the chance of fire by providing a barrier between the interior wall and the exterior wall that slows the spread of flames or stops them entirely. Faced insulation cannot make the same noncombustible claim due to the flammable paper vapor barrier that is firmly attached to the insulation.
What happens if insulation is installed backwards?
So if it is installed upside down, the paper moisture barrier can actually keep moisture in-between the paper and the sub-flooring. This can lead to mold issues, as well as structural deterioration. Also, the paper is flammable so not properly installing it can create a fire hazard.
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.
Is it OK to use unfaced insulation in attic?
When installing between the roof rafters of finished attic spaces, you can use either faced or unfaced batting. When using insulation that has paper or plastic batting, that moisture barrier should face outward toward the attic space.
Can you use r13 in attic?
Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. 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.
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.
