hurricane impact doors for Wind Load Construction
For Service and Insulated Coiling Doors
The concept of rolling doors designed to withstand wind loads is not new; people building in
At Cookson, we have dedicated many years to developing and validating analysis methods to help provide the design tools you need to specify exterior door designs with the confidence that they will provide the protection required. Our purpose is to provide a door system that will perform to your specifications and continue to do so for the life of the door.
Heavier gauge slats do not necessarily result in higher wind load capacity for the
In today’s environment, wind speed is only one factor needed to design a commercial door system. Many people in the past determined the value of the dynamic pressure that corresponded to a wind speed to drive the design. This is better than nothing, but it does not consider a number of very important variables that affect how much wind force is exerted on a structure
Our wind load-rated overhead doors take into consideration design load determination, door mounting and fastening methods along with specific door guide gaps. Cookson is proud to offer one of the top comprehensive product offerings of wind load designed rolling doors in the rolling door industry.
Cookson’s wind load-rated overhead doors are validated through several third-party testing facilities to meet one or more of the following performance criteria:
- ASTM E 330
- Miami-Dade County test protocols TAS 201, TAS 202 and TAS 203
- Florida Building Code (FBC)
- Texas Department of Insurance (TDI)
- Signed and Sealed Calculations

Wind load ratings and specifications can be complicated. We are here to help.
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
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.
