Adding rigid foam to basement floor after partition walls
I’m looking to add rigid foam to my existing concrete basement floor. The basement already has partition walls installed including drywall. How should I detail the foam to wood stud wall connection? I suspect that I should remove a strip of drywall off the bottom of the wall?
I would also include a layer of poly between the slab and the foam. Unfortunately when the walls were built (in the 80’s) there was no barrier installed between the bottom plate and the slab.
The home is located in climate zone 7 in Ontario.
I browsed some articles about insulating floors but didn’t come across this issue. If there’s an article I missed please let me know.
