smoke tested my house looking for drafts. Found lots...

I've seen a guy use thick painters plastic that was taped into place when I was watching a guy using a blower door to pressurize before with new construction before drywall was up. I think he was an energy rater or something, he also tested the ductwork for air leakage too. I've never seen a fiberglass job actually look good before, complete fill top to bottom, not wavy at all, completely straight with the studs without pocks, divots, compression, or buldging. The amount of time it looks like it took made me wonder how the extra labor cost of doing fiberglass right could possibly be cheaper than dense-pack cellulose. Anyway, thick plastic or even a sheet of cardboard taped in place, remove the fan grille first so you can get a flat surface and avoid taping it to the bumpy stuff on the ceiling.
