Products / WindBar

WindBar is a patented external purlin system for standing seam metal roofs that uses non-penetrating stainless steel seam clamps, a square bar and a WindStopper foot that holds down the middle of the panel. The product page states it can increase a metal roof's wind uplift performance by up to 300 percent and reduce wind noise by up to 95 percent, says it is designed to help meet ASCE 7-98 wind guidelines, and says it is custom designed per project from a quote request and can double as part of a snow retention system.
