How do you keep a continuous air barrier in a vented attic over a porch?
This duplex is being built in zone 4C (see photo). The vented attics are going to be blown with cellulose.
My concern is the part of the attic that extends over the front porch. The porch roof will be cedar car decking. The plans don’t call for any insulation or air barrier in this part of the attic – just cardboard baffles at the exterior wall plane to hold the cellulose in place.
Are insulation or an air barrier needed there?
