EFCO is proud to introduce this exciting new page to showcase industry leading engineering tools! This page will be periodically updated with charts, software or other tools to increase your productivity by simplifying difficult engineering and performance aspects of architectural aluminum systems. Please visit this section periodically for EFCO product support news and technical information.
  Wind Load Charts
This is the industry's most versatile wind load chart. Please click on the "Wind Load Charts" image. Wind load charts are an extremely useful tool to properly size mullions to resist wind pressures, by inputting the mullion span, "tributary width," design pressure and desired deflection limits. The user can generate a custom single span wind load chart for most EFCO's available curtain wall and storefront mullions, for any combination of three design wind pressures and deflection limits. An efcocorp.com account is required to access this application. If you do not have an account, please register here.
 
 Other Features Include:
 • Versatile - allows charts to be modified to
   any job specific wind pressure & deflection
   criteria.
 • Fast - can have several wind load charts
   generated in just minutes.
 • Outputs in both English and Metric units
 • Allows quick comparisons of different system
   configurations.
 • The only one of it's kind in the industry.
