Zip Sheathing and interior vapor barrier
I’ve been residing chunks of my house. I started pulling the sheathing off. Much is rotted due to nonexistent window flashing and incorrectly lapped Typar from 20+ yrs ago.
I started using Zip sheathing and taping all seams. As I do this, I pull out the R11 fiberglass batts, leaving the faced vapor barrier from the fiberglass batts on the interior. Then, I put in R15 Roxul batt insulation ,Zip Sheathing and zip tape.
LP smartside will go on top (was cedap clap).
My question is, should I be leaving the faced bat vapor barrier on the wall interior with taped zip sheathing in Massachusetts?
