ip sheathing drywall flange – using drywall as ceiling air barrier
I’m using Zip sheating on a two story house. I plan on using a detail that Steve Baczek uses where he adds a 10-12 inch flange of zip sheathing on top of the double top plate. This allows you to run a couple beads of acoustical sealant to seal off the ceiling drywall for a continuous air barrier.
