My home is balloon framed and while I've got the upstairs gutted, I'm going to feed the outside walls full of cellulose. Someone mentioned a vapor barrier problem with blown-in and I was curious about this. I'm aware of other homes around here having it blown through the exterior and obviously no vapor barrier there. Is it more a climate thing that maybe isn't necessary here (SE Ohio)?

Also I've seen people here saying that the Kraft faced insulation should have the vapor barrier on the living area side. All the job sites I've seen here, the walls are done that way, but the floors and attic are opposite. In other words the vapor barrier is toward the outside. Is it regional or is everyone (including my DIY jobs) wrong?

With very few exceptions, the kraft faced vapor barrier should be towards the heated space.

If you are concerned that your walls will not have a vapor barrier when you blow in insulation...repaint the interior walls with a vapor barrier primer.
