Its brief specification sheet prints air infiltration to ASTM E1680 and ASTM E283, water penetration to ASTM E1646, ASTM E331 and ASTM E2140, wind uplift to ASTM E1592 and UL580 Class 90, field forming up to 300 feet for the 16 inch panel, and a 30-year paint-finish warranty. Fabral describes it as having the highest wind uplift resistance of any standing seam panel system.
