Another poly question (ceiling)
I have been told told by the builder to expect to have poly required by the inspector on the ceiling and walls. (Ontario Zone 6) I will be using mini splits for heating and cooling, so yes A/C in the summer. My question is if regular 6mil poly will be any issue on the ceiling?
Its a vented attic space that will have minimum R60 blown in cellulose.
As for the walls I plan on using Smart Membrane, if I can’t convince them otherwise, as I have 6″ of polyiso on the exterior.
