Rim joist insulation
Live in Canada, winters are cold. Last couple of years we have noticed frost build up on the baseboards in a couple of spots and now I know the problem, but don’t know the fix and I am looking for ideas.
Basically, we have a double rim joist half filled with concrete and one lonely piece of fiberglass pink insulation in between. Needless to say there are some big cold spots upstairs. See my detail attached, wondering if anyone has some good ideas to deal with this that do not involve ripping off rim joists :).
Thought drilling some holes from the exterior and blowing in dense pack might be the best solution?
