Seal inside seams of Zip-R sheathing?
Climate zone 5
we are working on air sealing details on our new home build that is sheathed with Zip R sheathing.
the exterior taping/liquid flashing was done per specs. The bottom of the sheathing was taped to the foundation wall with zip tape augmented with 3m 90 adhesive.
Would taping or caulking (or liquid flashing) the inside seams (polyiso) help with air sealing? Or would this just be a waste of time/money?
if it is worth it, what works on plain (un-faced) polyiso?
Thanks in advance.
