Insulating Rim Joist Question
I have a question about insulating the rim joist in my basement ceiling. House is only 8 years old and weíre plugging away on finishing the basement and are at the ceiling now. I plan on just adding fiberglass rolls/batts between the joists and have had non-faced fiberglass in the rim area (see photos) since new without any issues. Before I do anything else, I want to know if fiberglass in the rim area is sufficient or is there a better way? Iím thinking spray foam would be better but cost is a factor as always. I just want to do this once and donít want to have to worry about it again 5, 10, 20 years down the road so I want to make sure I do it right. Foundation walls are poured and we live in the northern Midwest and have very cold winters, below zero air temps are very common.
Also in using the fiberglass rolls/batts between the joists Iím assuming unfaced friction fit would be fine? Or would I want kraft faced?
Thanks for any help or feedback!
