| Fiberglass Insulation |
|
Nucor recommends that the fiberglass insulation be installed in two layers, as shown above. |
| Layered Insulation |
|
This recommended layer method of insulation helps ensure that there are no gaps in the insulation. (Gaps in the insulation can cause condensation problems.) |

| Roof Deck |
|
Roof deck is fabricated in accordance with SDI specifications and tolerances. Nucor does not offer warranties on liner decking. |
| Panel Clips Fasteners |
|
Panel clips fasteners must engage the Z-Bar member. Self-drilling fasteners without a washer are utilized. |
| Z-Bar Fasteners |
|
The Z-Bar fasteners must engage the deck. Self-drilling fasteners without a washer are utilized. |
| Vapor Barrier |
|
Vapor barrier is required in all
composite “CFR”™ applications to help
avoid condensation.
Vapor barrier is not provided by Nucor Building Systems. |
