Insulation for Nucor CFR™ Systems
Nucor Building Systems recommends that insulation be used in all “CFR”™ roof applications to avoid problems with
condensation forming. Insulation also provides a buffer between the purlins and the “CFR”™ roof to reduce noise and
possible damage due to metal-to-metal contact. Insulation requirements are as follows: |
Short Clips - |
2” to 4” of insulation compressing to ½” over roof purlins.
(EPS foam spacers available for limited use in un-insulated areas.) |
Tall Clips - |
2” to 6” of insulation compressing to ½” thickness under thermal block at roof purlin locations.
Thermal blocks are required when tall clips are used.
(1 ½” thermal blocks with adhesive are available for limited use in un-insulated roof areas.) |
Applications - |
Fixed or floating roof clips may be used as follows:
Roof Structural Type Panel Run, Purlins Fixed Clip Floating Clip, Joists Floating Clip Floating Clip |
