Intello at Ceiling with Closed Spray Foam?

brad17 | Posted in General Questions on

Hey folks
We are using Intello Plus at inside of all our exterior walls, which have rockwool batt. Do I also need to run the intello on the interior side of our roof as well, which has R60 closed cell spray foam?

    All that closed cell spray foam is a vapor barrier so the intello won't do much.

    Is this already insulated? R-60 is a lot of cc foam. Have you considered other options involving batts. At least flash and batt?
