standing seam on purlins | Ask The Experts Forum

Michelle Jones 12/22/2017	My roofer just installed a beautiful standing seam roof on purlins. We intended to spray foam the entire attic with closed cell, but now we're getting mixed messages from the contractors that standing seam is incompatible with closed cell and without a vapor barrier, there's no way to insulate this. What are my options to be able to use the attic space?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22722/find/
Eric Novotny An informed customer is the Best Customer! 12/22/2017	Incorrect. Closed cell is a vapor barrier. Can you see the backside of the metal in this case? Can you post a picture of the attic or email me one? Email address: [email protected]	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22723/find/
Michelle Jones 12/22/2017	Thanks for your reply. I'm attaching a photo. You can see the metal roof from inside the attic.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22724/find/
Eric Novotny An informed customer is the Best Customer! 12/22/2017	I recommend that your spray foam contractor install a small layer of fan fold or otherwise thin insulation, to keep the Spray foam from being spray directly to the metal here. The foam would be placed between the rafters and the SPF (Spray Polyurethane Foam) contractor can then spray overtop the foam and insulate the rafter/roof assembly that way. This will allow the metal to move independent of the foam and will allow the roof to be serviced without damaging the foam if you ever have a scenario where the roof is damaged.
