I recently gutted two closets down to the studs in my old house. I even took out all of the old plaster and lathe in the ceiling. I plan to sheetrock the new closets next week.
I've got no insulation right now above the closets. I was thinking about doing spray foam above them then sweeping some of of my blown in fiberglass over the top of the spray foam (I have a lot of blown in fiberglass up there, about R-60). Would it be ok if I just used some canned spray foam? The areas aren't that big, but I'd like to get the best air sealing that I can for maximum energy efficiency. Would this type of foam be a bad idea to be in direct contact with the studs? I know some people believe that open cell spray foam can hold a lot of moisture which might rot the wood.
Could I use a few cans of spray foam? Or should I look at a small diy spray foam kit? Eventually when I remodel my kitchen and my bathroom I will also gut the rooms down to the studs and I'd like to insulate above the rooms the same way. Thoughts? Advice?
