WindBar Galvanized Finish for Standing Seam (6 Foot)

The Windbar system acts as external purlins for your standing seam metal roof. It adds uplift strength to new and existing metals roofs. The principle behind the WindBar system is the patented WindStopper foot. The bar spans between non-penetrating clamps, placed on each seam, with devices mechanically fastened to the bar that extend down to the flats of the panel. The foot of this device, also known as the WindStopper, holds down the middle of the panel and prevents uplift under negative wind pressure. This is a common issue with many standing seam roofs, located in areas that experience high wind conditions. If left untreated, many of these buildings experience interior noise levels that can make daily operation difficult.

One WindStopper per panel, centered, is needed for standing seam panels with seam spacing less than 18". Two WindStoppers per panel, uniformly placed, are required for panels with seam spacing of 18" to 24". Three WindStoppers per panel, equally placed, are required for panels with seam spacing greater than 24". WindStoppers rest against the panel and are only mechanically attached to the back of the bar. Do not mechanically mount the feet of the WindStoppers to the flats of the panel.

The WindBar system typically has more rows than even the most robust snow retention design. It can therefore operate both ways. The main distinction between the SnoBar/ColorBar and WindBar systems is that the WindBar's WindStopper is required, while the SnoBar/ColorBar's IceStopper is optional. The fact that WindBar is trusted on a number of Antarctic research sites is one of our proudest demonstrations of its efficiency for these two different purposes. With gusts up to 200 mph, Antarctica experiences the highest sustained wind speeds of any continent.

Our 1" x 1" galvanized bars with gator shield coating are included with standard WindBar systems. Although the 2" extruded aluminum bar is an available option, we believe that given the robust design of this system, it is often overkill and unnecessary. When the standing seam panels are wider than 24 inches and winter precipitation is common, the aluminum bar is required.

Custom powder coating is available for WindBar systems at an additional cost. A physical color sample is typically required for accurate color matching. For information about pricing and availability, call us at 1-800-766-5291. Color-matched bar systems are made to order and take three to four weeks to produce. Customers can purchase a WindBar system in mill finish and spray paint it once it arrives or have it coated locally if they would rather take a speedier or more affordable route.

In contrast to our snow retaining rail systems, SnoBar and ColorBar, where the IceStoppers are optional, the WindStoppers are critical for the performance of a WindBar system and are a requirement. Although essentially the same thing, IceStoppers, and Windstoppers have completely distinct uses in the two systems. The Windstopper attachments sit against the panel's flats and mechanically fasten to the back of the bar. Although the Windstopper feet are not mechanically attached to the panels, they exert pressure on the flats, pressing them firmly against the roof structure. When there is strong wind, this pressure stops the panels from flexing and vibrating.
