   Where is your building located? If your in a Heating Climate than I would absolutely add a vapor barrier. To add a vapor barrier, or not, really depends on your locale.

   *I'm building near Cincinnati. It seems the norm around here is no ceiling vapor barrier. They say it's due to the humid summers??? Very few contractors will install cellulose but I found a place near Fernald called "Valley Insulation" that handles blown in cellulose. They recommended against a poly vapor barrier too but claim that with the dense pack cellulose acting as the air barrier one is not needed.

   *Why would it be full of holes? If you did a proper job at installing it, it shouldn't be. Even if there are a few small holes in it, it should still stop close to 100% of all vapor diffusion, and in a cold winter climate this is important to try to stop a high percentage of vapor diffusion, or if possible, all of it.

   We're getting ready to insulate the ceiling in my new house. The house was built with ICF's and it has ridge vents and soffit vents. The builder has recommended blown in insulation over bats because of the cost saving. I asked him about a vapor barrier for the ceiling if we use blown in, he said in a ceiling it usually isn't necessary. Don't you need to keep moisture out of the attic insulation to preserve the R value?
