Insulating Rim Joists Without Foam
Hey guys, I had previously air sealed my rim joists with a combination of spray foam and rigid foam board.
However, after a few water leaks (that have been subsequently repaired), I have grown increasingly paranoid about the ability for spray foam and rigid foam to conceal water and/or pest damage.
Therefore I was wondering if you guys could recommend another method of insulating the rim joist that would still allow access in the event it was needed. I know fiberglass insulation isn’t best practice but would it be ok to use provided that the perimeter of the rim joist is adequately sealed with spray foam? Would Roxul or cellulose be a better option over fiberglass?
I just generally don’t feel comfortable doing anything that would limit access in the future. When our front door leaked I noticed some water dripping. When I cut out the rigid foam blocks, there was plenty of wet wood behind the foam. Another form of insulation could’ve allowed it to dry out quicker while also help reveal the problem sooner.
Thank you very much for your time and help everyone!
