Comfortbatt/Rockwool/Roxul and temporary compressibility
I have some framers coming tomorrow and have a basement wall being constructed inside the existing wall so as to insulate inside the stem wall. I’m planning on using rockwool comfortbatt at the bottom of the wall to allow for some breathability of the stem wall.
Will I be able to squeeze the 5.5″ comfortbatt through a 3-3.5″ wide opening (it will expand to full size, once in the wall)?
It hard to tell if it can compress that much, even intermittently, though I’m guessing so.
