This is on a pole barn. If a roof is aluminum and we are switching to a metal roof that will have 3: 3' x 10' skylights in it. Would you recommend a vapor barrier(1/2" thermax) to prevent dripping? This is cold storage from my understanding with a concrete floor. I am thinking only if he has livestock or heating it does he need a vapor barrier especially if he has 3 skylights in it.

I agree with you. Vapor barrier is not necessary provided it has concrete floor, will not have conditioned air, and will not be used for animal confinement.		Todd Miller Isaiah Industries, Inc. 10/28/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/12224/find/
