Product Description 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 and 22 (by special request only)
Lengths: 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 and Architectural Series
Manufactured: Houston, Caryville, Mattoon, Rome, Salt Lake City and Atwater
Usage: New and retro fit applications.

Oil-canning is not a reason for rejection.
| Feature | Benefit |
|---|---|
| No panel penetration is required over the building envelope other than at the end laps, and panel ends which are connected by a compression joint. | Specially designed to seal out the elements. |
| Panel side laps arrive at the job site containing a sealant. | Contributes to the system’s weather tight construction and ease of erection. |
| Optional weather tightness warranty. | Severe weather tightness and additional customer confidence. |
| Factory notched at both ends with pre-punched holes. | Field installation can commence or finish from either end of building. |
| End laps have a 16 GA. backup plate with pre-punched holes. | Solid connection at end laps and proper fastener spacing. The pre-punched holes improve erection and ensures proper panel placement. |
| High or Low Clips | Accommodates variety of insulation systems including 1″ thermal spacers at the purlin. |
| UL 90 | Lower Insurance Costs |
| 80% less exposed fasteners than traditional side lap panels and all fasteners are long life. | Increased Weather Tightness |
| Panel available Royal K-70 paint system | 20 year finish warranty |
| The side lap has been tested for air infiltration and water penetration under ASTM E283 and E331 methods | Minimal air infiltration and water penetration and acceptability among specifiers. |
