Products / Snap-On-Seam SS15

Snap-On-Seam SS15 is a non-structural, engineered snap-together standing seam system made of two components, the panel and a continuous interlocking seam cap, and installs non-directionally for control over seam layout on complex roofs. The product page prints a solid substrate requirement (plywood sheathing, nail base insulation or corrugated metal deck, with 5/8 inch plywood and clips at 20 inches maximum for UL90 constructions), roof slopes as low as 3:12, 24 and 22 gauge steel, .032 and .040 inch aluminum and 16 and 20 ounce copper, seam spacings of 12, 16 and 18 inches, and an optional factory-applied non-curing sealant. It lists performance tests to UL-580 wind uplift, ASTM E331 and ASTM E283.
