Snap-On Panels have been designed for use in roofing, mansard and fascia applications. Snap-On Panels are designed to be installed over a waterproofed solid substrate and a minimum 3:12 roof pitch. Snap-On Panels are to be factory roll formed in continuous lengths (minimum panel length is 4 feet).

These panels are ideal for specification
on applications where roof transitions are required. The simplicity of the pan design combined with corrective leveling provides superior flatness and allows for greater workability on site.

UL 90 Classified
Steel Snap-On Standing Seam and High Snap-On Standing Seam Panels carry a UL 90 classification for wind uplift when fastened to an underlayment assembly including 5/8” plywood or OSB (oriented strand board) laminated to rigid insulation (UL Construction No. 351 & 352). This is one of the few UL 90 Systems that does not require sealant between plywood boards. For further details contact Petersen Aluminum Corporation.

Air and Water Infiltration
Petersen Snap-On Panels meet the full performance requirements of the ASTM E 283 air infiltration test and the ASTM E 331 water penetration test when applied over a solid substrate. For complete test results, contact Petersen Aluminum Corporation.

Materials
a) 24 ga. G-90 hot-dipped galvanized steel
b) .032 3105-H14 aluminum

Trim
All flashing and trim will be fabricated by manufacturer or qualified fabricator. Flashing shall be PAC-CLAD aluminum (.032-.080 gauge as specified) or PAC-CLAD steel (22 ga. or 24 ga. as specified). A 20 year, non-prorated warranty shall be supplied covering finish performance.

Curved Panels
The 1" high Snap-On Standing Seam Panel can now be curved to a concave or convex radius, with a minimum radius of
9 ft. This panel is ideal for barrel vaults and entranceways. Curved panels must be installed over a waterproofed solid substrate.

Installation
PAC-CLAD Snap-On Panels shall be installed over solid decking (5/8" plywood, nailboard insulation or equal) with an underlayment of 30# (min.) roofing felt applied horizontally from eave to ridge. Panels shall be fastened using Petersen Non-Penetrating Clips, fastening on 18" centers (max.). Minimum slope at 3:12 pitch. Consult a local architect or engineer for requirements of local codes and conditions.

*24 ga. panels listed in bold print are UL-90 Classified over solid substrate. See roof deck construction in Underwriter Laboratories roofing materials and systems directory.
