6 inch EPS in bonus room?
I’m in the process of finishing a bonus room. I have rafters that are 11 inches deep.
I found a deal on 6 inch EPS foam. I planned to cut-and-cobble, and leave 1 1/2 inch ventilation gap between the roof deck and the EPS, then fill the remaining 3.5 inches with fiberglass batt insulation.
Is this plan solid? Should I use faced or unfaced insulation?
Thanks in advance.
