EPS rated at 10 PSI compressive strength ok for basement floor insulation?
I am getting ready to renovate the basement of my 1978 walkout. I’ve been pouring over all the data here (which has been extremely helpful) and I have a plan for insulating the walls and floor. One final question I have around using EPS on the basement floor (floor assembly will be EPS + Plywood + finished floor). It looks like the only type of EPS I have available to me locally is rated at 10 PSI compressive strength. Most information I see on this site suggests at least 15 PSI. Is 10 PSI sufficient for my application?
