Almost two years ago I moved into a newer house (5 years old).

I've setup my humble workspace in our attached garage - which has been completely sheet rocked.

I live in MN, I want my heat for winter!

So last year I installed faced bats on all the exterior walls. This year I want to do blow-in insulation above the garage. The rest of the house is blown-in on top of a vapor-barrier.

My problem presents itself in the form of the "vapor barrier" for the ceiling in the garage. I want to know what your thoughts are on my options without having to drop all the drywall.

Is it acceptable to place the barrier over the ceiling joists and into the spans between, and overlapping electrical - as long as it's between the warm side and the insulation?
