Roof Insulation

I have a strange type of metal roof an a small commercial building approximately 2,100 S/F. I need to insulate the bottom of the roof (ceiling inside) and have no idea how to approach the project. Attached is a quick rendition of how the roof looks. The problem I have is that the roof is structural and consequently has no under support IE rafters or joists. The roof is supported by the front and back walls of the building with an I beam splitting the span in the middle running perpendicular to the direction of the roof. The result is large areas (approx. 500 S/F) that need to be covered without the typical methods of support. Please see the attached drawing for clarification of how the roof works. Thank you!

Would you want to consider spraying the bottom side of the roofing with closed cell urethane foam?		Todd Miller Isaiah Industries, Inc. 5/8/2014	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19484/find/
Sure, I'm looking for the most cost effective way to regulate the temperature in the building but I also need to satisfy the fire inspector so I need some sort of foil covering as well.		Guest User 5/12/2014	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19485/find/
There are fire rated foams. For the most part, foil products do not contribute toward a fire rating.		Todd Miller Isaiah Industries, Inc. 5/12/2014	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19486/find/
Thank you, where would I look for such a product?		Guest User 5/12/2014	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19487/find/
A commercial rofing contractor or else a commercial insulation contractor should be able to help you.		Todd Miller Isaiah Industries, Inc. 5/12/2014	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19488/find/
