Intello at Ceiling with Closed Spray Foam?

user-6445625 | 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? 
Thanks!

    Brad,
    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?
