Temporary fix

Since we have lived in our house we have had a room with 6 large skylights. We were not the original installers so they were likely 25+ years old. While they were nice for light, they have leaked and wasted heat as the room would cool down quite fast. To deal with the heat issue I added some wood trim close to the ceiling level and installed 3M plastic to create an air barrier to the skylights during the colder months.

We recently had our roof replaced and had these skylights eliminated. My plan is to remove the drywall shafts, insulate, and drywall the openings flush with the ceiling. However, it is getting cold and I do not have time to make the repairs at this time so I am going to install the plastic one more year. I am wondering if I should also add some insulation in the shaft, and if so, should I put the insulation up to the roof deck or keep it low near the plastic? Or does it even matter?

Thanks for any input!

 

I would think close to the ceiling height would be the most effective.
I've painted more of the 'holes' than I care to remember and it gets pretty hot up in there during the summer.

 

I'd probably put a sheet of foam over the opening, not just plastic. Your insulation will go in your ceiling joists. The shaft could be completely demolished to get it completely out of the way for better insulating.

 

Sorry, if I wasn't clear. I will be removing the skylight shafts to allow the attic to vent properly. Then, insulate the attic space, install new drywall, tape, and respray the texture.

The issue right now is it is getting late in the season and I do not have time to take on this project right now. So I am planning to just reseal the openings like I was doing in the past with 3M plastic. I am mostly wondering if I should add some insulation in the shaft now that the windows are gone or does 1/2" ODB and shingles have a better R-value than the old skylights did?
