I'd like to add some insulation to my attic. I just had the house sided and re-roofed, so I now have a vented soffit and ridge vent. I know I will need to put in some rafter shutes, baffles or whatever you want to call them in between the rafters. I presently have about 7 inches of blown in insulation on my attic floor which is under the reccomended amount for S.Eastern Pa. So my question is this , Can I use unfaced batts on top of the blown in insulation running them perpendicular to the joists, or do I need to use more of the blown in insulation? Thanks.

Before you add insulation, use caulk and spray foam to seal all electrical and plumbing penetrations into the attic. Seal the attic hatch, also. Otherwise, the insulation does no good.
