Best way to insulate attic
My attic currently has R19 foil faced fiberglass batts installed. I would like to air seal the entire attic and re-insulate with blown in cellulose.
The original plan was to cut EPS to fit between the stud bays and seal with great stuff, followed by the fiberglass and blown cellulose. From my understanding, EPS or any rigid foam is not worth the labor for this particular application.
Should I remove the fiberglass batts, caulk/foam the seams and openings, and then reuse the fiberglass followed by cellulose?
My concern is the vapor barrier. I’m up in the Michigans Upper Peninsula and it gets brutally cold up here during the winter months.
Any help planning/recommendations is greatly appreciated.
