In the process of finishing my basement. Before I get too far need to decide whether to insulate the rim joist or not.
Believe it can make the basement more comfortable/energy efficient from what I've read. However I've read conflicting things about what to use and maybe to do it at all. Fiberglass is a no no from what I've read as its vapor permeable and can cause mold and mildew to grow in it.
Froth pack for closed cell foam sounds the best for air sealing and insulation, but Ive read some thougths that this can lead to condensation on the other side of the rim joist leading to rot as it cant ever dry out if any moisture vapor gets in there.
Thoughts from any contractors or all around handy folks?
