Guide to 2″ Snap Seam Panel Installation

Standing seam for interior

The 2″ Snap Seam panel is a versatile and efficient option for standing seam metal roofs. Its installation can be tailored to suit various needs and preferences, making it a popular choice among homeowners and contractors alike. This guide will walk you through the installation process, compare it with other products, and highlight the pros and cons of using 2” Snap Seam panels.

Installation Methods for 2″ Snap Seam Panels

The installation of these panels is unique because there are two different ways you can achieve a complete installation.

Snap-Lock Installation: The panels will be snapped over the clips, with the female leg snapping over the male leg. This method results in a complete installation that has been fully wind uplift tested with a UL580 rating.

Seam Installation: After snap-locking the panels in place, you can then run a seamer up the panel’s seams one time. This method is quicker and easier than traditional double-seamed panels and has been fully tested for wind uplift (UL580 rating), air leakage (ASTM E-1680 rating), and water penetration (ASTM E-1646 rating).

Comparison with Other Products

The new 2″ Snap Seam is a Standing Seam panel with several differences that set it apart from other Standing Seam panels.

Compared to Tru Snap: The 2″ Snap Seam allows for more effective use of butyl sealant. The hot or beaded mastic can be applied into the seams more easily, providing better protection against water intrusion.

Compared to Mechanical Lock Panels: Installation of the 2″ Snap Seam is faster and easier because there is no need to hand crimp at each clip location. The snap-locking installation holds the panels in place without the need for additional crimping or clamping.

  • Single seaming is required if chosen, unlike most panels that require a double seam.
