Hi. I'm new to icf construction but have done some research. I'm currently taking a class on concrete and have to write a paper on icf's. my ? is after the concrete cures in a icf wall. Do u tear down the foam forms? Or just leave them up? I saw on the fox block site there recyable but it didn't say if they tear them down?

This seems to be a very naieve ?. All ICFs are concrete forms. Foam stays in place, normally, concrete inside. That is the insulating part. Right? Concrete structure and adds thermal mass. Yes? Study more!
