Too many vapor barriers! Help!
This is the exterior wall assembly on this house: Vinyl siding, 1″ polyiso, then flash and batt (1″ closed cell in cavity. Then clear plastic was applied on the interior face of the wall. I’m thinking that has to go. What are our options? Is it possible to vent the plastic with strategic slits in the plastic? The drywaller is scheduled for next week, and I just pointed this out to the owner today. Thanks in advance for any help I can pass on to add weight to my advice to him!
