I thought originally you were finishing /insulating the roof line to achieve a lofted ceiling effect ? ?

No sir not going for a loft look. I stapled reflective foil to the bottom of the top of the rafters, up where the roof deck is nailed to the top of the trusses. So that creates an air barrier if 3.5 " because my rafters are made of 2 x 4's . Then there is the bottom of the trusses, this is where I stapled R13 Kraft face 3.5 " fiberglass batts. I did this because it gives me an instant part time ceiling while I figure out what I actually want for the permanent ceiling. Once the permanent ceiling is in place then I will blow in fiberglass insulation to almost completely fill the space from the batt insulation to the bottom of the reflective foil. I'll end up with around R40 + which should be fine for Georgia. I just walked out to the garage it is almost 90 out right now. I have the mini-split set at 79 degrees and it feels great in there.
