 |
| 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 retrofit on existing structures. This panel design provides a high degree of weathertightness 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 |
Limitations: Recommended for roof slopes of ¼:12 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. |
| Length: 50' maximum is standard but longer lengths available by special request. |
|
| Dimensions: 24" wide by 3" high |
Usage: New and retrofit applications |
| Fasteners: Concealed fastening system. The clips are available as floating or fixed. Two different clip heights are available to allow for thermal blocks. |

Features: - No panel penetration is required over the building envelope except at the end laps, and panel ends which are connected by a compression joint |
Benefits: - Specially designed to seal out the elements - Contributes to the system’s weathertight construction and ease of-erection - Severe weathertightness and additional customer confidence - Field installation can commence or finish from either end of building or on both sides simultaneously - Solid connection at end laps and proper fastener spacing. The pre-punched holes improve erection and ensures proper panel placement - Accommodates variety of insulation systems including 1" thermal spacers at the purlins - Increased weathertightness and improved appearance - 20 year finish warranty - Minimal air infiltration and water penetration and acceptability among specifiers |

| Note: Oil-canning is not considered grounds for rejection of any panel system. Oil-canning can occur in any panel with wide flat sections. Heavier gauge, embossing, striations, flatter sub-frame systems and support from a solid sub-deck can all help to minimize oil-canning. |
