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 - |
4” to 6” of insulation compressing
to 3/4 ” 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 determined by the following:
