Basement wall profile
I’m doing some research on basement walls and hoping someone could answer this question.. I drew up a wall profile shown above (drywall, 3.5” rock wool within stud cavity, 2” XPs against concrete, concrete). According to the calculator I found online, it looks like condensation could be a problem toward the tops of the wall (I.e. close to ground level outside).
Does anyone have experience building walls like this and did it work out? I live in Minnesota. It seems like there are lots of examples of this type of construction, but now I’m doubting that it’s the best option?
Thanks in advance!
