Should I use EPS/XPS or spray foam to insulate basement walls with a brick texture?
I am looking to add a few bedrooms and a bathroom to my walkout basement. It has poured concrete walls on 3 sides, but the poured concrete has a brick pattern / texture to it complete with simulated mortar joints. Since this is an uneven surface, I am wondering if EPS/XPS is an option or if I have to go with spray foam insulation to fill all the voids?
