I'm insulating my garage door (in anticipation of a garage A/C :eusa_danc) and picked up 4 sheets of 1/2" foil backed R2.9 styrofoam and 4 sheets blue 3/4" R4 foam board to cut and stick in the panels. I might be able to cram another 1/2" foil in there and have foil on both sides but we'll see how tight it is once I get what I have in there. Then again there is always great stuff to tighten things up.
So, should I put the foil facing the outside or the inside? I'm thinking outside since I want the heat bounced out as much as possible.
