Roof Insulation | Ask The Experts Forum

Jim Eiman 5/7/2014	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!

Guest User 5/12/2014	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.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19485/find/
Todd Miller Isaiah Industries, Inc. 5/12/2014	There are fire rated foams. For the most part, foil products do not contribute toward a fire rating.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/19486/find/
