Hey guys so this fall I took apart my garage wall and ceiling (have a bedroom above garage. 3 wall of bedroom are exterior and floor is ceiling of garage.) So I got a company in to spray foam the joining wall and ceiling of garage but my garage has a drop ceiling it's about 2 to 3 feet below joist of floor above. So I wanted to blowin cellulose insulation into that cavity for extra insulation. The walls I have insulated with fiberglass and 6mil poly. I have put 6mill poly on ceiling and ready to blowin insulation but now my brother in law mentioned that I might be mold because there might be small areas of air leaks which I don't really feel. Wanted to know if anyone here does insulation for a living and can give me an idea if I should do the blow in insulation or just leave it with the spray foam on the joists (4inch 2 pound closed cell foam).
