SNAP-CLAD Standing Seam Metal Roofing SNAP-CLAD Panels feature architectural panel aesthetics as well as structural panel performance. SNAP-CLAD Panels, produced in continuous lengths, are Herr-Voss corrective leveled to provide superior flatness and feature an optional factory-applied sealant bead for improved weather resistance. (Minimum panel length is 4 feet) SNAP-CLAD Panels feature a 1-3/4” leg height and a continuous interlock for improved structural performance and wind resistance. A concealed fastener clip system has been designed to allow for thermal expansion/contraction while providing extraordinary hold-down strength. Two clips are available: a standard clip for most mansard and fascia applications and a high-performance clip for roofing application and UL 90 rated assemblies. SNAP-CLAD Panels are produced in a labor-saving one-piece design. SNAP-CLAD Panels are available with:
SNAP-CLAD Panels are intended for use in roofing, mansard, and fascia applications. Substrates may include 5/8” (min.) plywood, nailboard insulation or equal with an underlayment of 30# (min.) roofing felt applied horizontally from eave to ridge. Other substrates may include metal decking, purlins or rigid insulation in conjunction with bearing plates. A minimum 3:12 pitch is recommended in most applications. Contact Petersen for detail assistance on projects requiring lower slopes. Consult a local architect/engineer for compliance with local codes. 
Eave Notching Factory-produced eave notching is now available at nominal additional cost on SNAP-CLAD Panels and Redi-Roof Standing Seam Panels. Factory eave notching saves on labor cost by eliminating the need for costly field cutting in providing a properly trimmed eave detail. UL Designations SNAP-CLAD Panels carry a UL 90 classification over a wide variety of substrates and assemblies including 5/8" plywood, purlins, and rigid insulation in conjunction with bearing plates (UL Construction No. 254, 255, 261, 303, 343, 508). SNAP-CLAD has UL-90 classification up to 16" O.C. on .032 and .040 aluminum. See roof deck construction in Underwriter Laboratories roofing materials and systems directory. For further details, contact Petersen Aluminum.
SNAP-CLAD Panels meet the full performance requirements of the ASTM E283/1680 air infiltration test and the ASTM E331/1646 water penetration test. SNAP-CLAD Panels have been tested for structural performance under uniform static air pressure differences per ASTM E1592. Please contact Petersen Aluminum Corporation for complete test results.
