Foam skim-coat on attic floor in new construction?
I am considering skimming the entire attic floor (top side of the drywall as well as the horizontal chord of each roof truss) with a half-inch or so of sprayed-in foam before adding the deep blanket of blown-cellulose. The location is mid-Michigan, and the rest of the house will be fairly tight. Is this a wise approach (structurally, financially, etc) or am I headed in the wrong direction? Thanks for your help.
