We are proud to offer one of the most comprehensive line-ups for windload design. Our service, insulated and fire doors can be configured to withstand the full range of specific wind load requirements including missile impact ratings. Click here to see how they withstood Hurricane Ivan.

Specified wind load ratings are available when mounting to steel, concrete and CMU, and have been validated through third party testing to one or more of the performance criteria listed below.

If you know only the wind speed and a couple of the other variables for determining the required wind load, the DASMA website has a wind load calculator that determines the approximate psf requirements. This should only be used as a guide.

In order to determine the exact PSF requirements the following variables are required: wind speed (in mph), exposure category, door area, mean roof height, roof slope, directionality factor, surrounding topography, zone, positive or negative pressure and internal building pressure.

If you need further assistance, our Architectural Design support team can help you in translating building codes or determining the appropriate wind load. Contact us to discuss your project.
