How to insulate an overhang in zone 3?
I have a small overhang on a second floor bedroom that extends over the front porch. I had planned to complete seal the overhang to isolate it from the rest of the structure and add R30 open cell between the warm and cold area. Another contractor has suggests that I should not seal this space. He would instead include this area in the building envelope while also spraying R30 open cell on the bottom of the subfloor. So should I create a sealed space or integrate it into the envelope?
