cc for sparse in ridge ceiling?

[sirbo]

Started placing battens on the rafter ceiling yesterday, 45*45 with cc 40, but in the middle of everything, I realized that cc60 should be enough since I'm going to install paneling. Also, I have no desire to cut all the insulation.

How have you others done it?

That's how it turned out, working on a roof is something you don't want to do more than necessary.
thank you
