Wind load is the force of wind creating pressure that glass must resist. A specific building’s wind load depends on its height, shape, relationship to surrounding buildings and terrain, as well as local wind speeds and the duration of gusts.
One key factor in calculating wind load is center deflection. Excessive center deflection can result in edge pull out and distortion of reflected images. Center deflection can also cause contact between the glass and interior components, such as room dividers and window blinds. Calculating wind loads becomes even more complex with insulated glass. These cases require a computer-assisted wind load analysis to adequately consider many variables, including:
For projects built in the U.S., Guardian follows the current ASTM E 1300 “Standard Practice for Determining the Minimum Thickness and Type of Glass Required to Resist a Specified Load.” This information represents in-service glass, superseding the traditional straight-line graph and other wind load charts, and may differ for other countries.
