| 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.) |
|
|
| Insulation - Insulation is not by Nucor |
| |
|
| 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. |
|
|
| UL90 Requirements- For UL90 Requirements, please contact Nucor. |
|
|
| Z-Bar Spacing - Z-bars (16 gauge minimum) are spaced either 4'-0" or 5'0" apart to accommodate standard fiberglass insulation roll widths. |
