Yes. Either wood or plastic would be a good idea. You are only going to be able to get narrow sheets of plywood through those holes, but just nail them up. If you use plastic, secure it with staples.
Can I put plywood on top of insulation?
While you can construct dams around recessed lights that aren’t IC-rated to keep insulation away from them, you can’t cover them with plywood. Doing so can cause them to overheat. Don’t install a moisture barrier on top of the insulation.
What do you cover insulation with?
After the insulation is installed, it is necessary to cover it up with a vapor barrier so the glass fibers are not inhaled. The best vapor barrier to use is roll of plastic sheeting. This vapor barrier is easy to install and does an excellent job.

Quote from Youtube video: One quarter inch from the edge firmly rub strip to the shutter to get a good bond.
Is it OK to cover insulation with plastic?
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 it OK to put plastic over insulation?
Install the plastic sheeting only after the insulation, wiring and plumbing have been completed. Stretch the plastic sheet tightly across the top of the wall and staple it to the studs and plates with a hammer-tacker, a tool designed to install staples quickly and efficiently.
Can I put plastic sheeting 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.
Is it OK to cover insulation in attic?
Ideally, the insulation is covered with kraft paper or house wrap before installing boards to ensure there are no gaps or openings left behind. Do not cover vents during this process. Sufficient ventilation is highly important in attic areas.
How do I cover insulation in my ceiling?
Common solutions for covering exposed insulation include:
- Sealing the insulation by stapling a polymembrane sheet over it.
- Installing paneling or sheetrock over wall insulation.
- Installing plywood flooring over floor insulation.
- Working with an insulation expert to ensure safe, code-compliant results.
Can I cover my attic insulation with plastic?
Yes. Either wood or plastic would be a good idea. You are only going to be able to get narrow sheets of plywood through those holes, but just nail them up.
Does ceiling insulation need a vapor barrier?
Fiberglass Insulation
Like other batt-type insulation, fiberglass has a predictable R-value if not compressed but is difficult to fit around obstacles without leaving gaps. In most climates, it needs a vapor barrier.
Does insulation need to be covered?
Because loose-fill or batt insulation on the attic floor and batts installed under floors are not exposed to significant air movement, they do not need to be covered on the exterior side.
Is it safe to leave insulation exposed?
“Fiberglass insulation should never be left exposed in an occupied area, according to the American Lung Association,” says ALA’s Godfrey. “Exposed fiberglass insulation, once in the air, does cause respiratory reactions, such as dry, scratchy throat and coughing, as well as acting as a skin and eye irritant.
What type of insulation can be left exposed?
What Type Of Insulation Can Be Left Exposed?
- It has been installed so that the paper facing is placed against the inside of the wall (against the sheetrock or other building material). …
- It has no paper facing at all.
- Fiberglass can be left exposed if it has a special flame-resistant foil facing.
Should you insulate attic 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. You can add insulation to the floor; the more the merrier. Just don’t put it in the eaves. Also, make sure the attic is well ventilated.
Should you insulate the underside of your roof?
In order to avoid damage to the roof deck, you should insulate ceilings to create an air barrier between the living space and an unfinished attic or airspace underneath the roof deck.
What insulation do you use for roof rafters?
Consider using high-density R-30 batts, which are as thick as R-25 batts, but fit into 2×10 framing. You can also add rigid foam insulation under the rafters, which adds R-value and eliminates thermal bridging through wood rafters.
