A metal standing seam roofing product attached to sub-framing using a variety of concealed, interlocking clips that provide for minimum panel penetrations. This panel can be used on new construction as well as retro-fit on existing structures. This panel design provides a high degree of weather tightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration, water penetration, and wind uplift).

Gauge: 24 (std.), 22 available by request

Length: 50' maxium is standard but longer lengths available by special request.

Fasteners: Concealed fastening system. The clips are available as floating or fixed. Two different clip heights are available to allow for thermal blocks.

Finish: Galvalume

Manufactured: Multiple facilities within NCI

Usage: New and retro fit applications.

Limitations: Recommended for roof slopes of 1/4:12 or greater. When using the fixed clip we recommend for double slope buildings 200' wide or less and single slope buildings 100' wide or less.(May vary upon extreme weather conditions.) Oil-canning is not a reason for rejection.
