I am looking for the same feedback.
I have already put up the 2 inch XPS boards from the concrete floor to the floor joists. I have already put in XPS board and foam sealed the rim joists.
I am ready to frame in front of my XPS but want to do the fire blocking that is required and want to ensure I do it correctly.
