Standing-seam Clamps Bring Older Roofs into Compliance with Current Codes and Wind Standards

S-5! has added to its line of WindClamps, designed to increase wind resistance for standing seam and other concealed-fastened metal roofs.

S-5! has added to its line of WindClamps, designed to increase wind resistance for standing seam and other concealed-fastened metal roofs.

The new WindClamp2X, as with all S-5!’s WindClamps, are small aluminum clamps placed over the roof’s seam at designated intervals to prevent male-to-female seam separation and/or seam separation from the roof’s mounting clip. S-5! WindClamps are a cost-compelling alternative for new construction and can also be used in retrofit applications to bring older roofs into compliance with current codes and wind standards.

Attaching these clamps to a roof’s seams have proven to dramatically improve wind uplift performance for more than 25 years. S-5! WindClamps increase—and often double—wind resistance, preventing multiple modes of failure, including seam separation and clip disengagement when used at roof clip locations. This clamp-to-seam technology has been a highly cost-effective solution to preserve rooftops in some geographic regions and/or roof “zones” with increased probability of extreme wind uplift conditions.

S-5! Now offers three WindClamp solutions for a variety of roof profiles:

  • WindClamp DL, designed for MBCI Double-Lok and licensees
  • WindClamp UD, designed for MBCI Ultra-Dek and licensees
  • NEW WindClamp2X, designed for other specific double-folded standing seams: Butler MR-24 and Varco Pruden SSR
