When severe weather comes, it’s essential that a structure’s windows and doors be able to withstand high winds and extreme pressure changes, so that the people inside are protected and major damage to the roof, walls, living space, and other property is minimized. Because of its large size (area), the forces acting on the garage door are tremendous, and in the event of the door’s failure, the pressure change within the interior of the garage or structure can cause devastating damage.

That’s why the demand for high performance windload-rated doors continues to escalate in areas prone to damaging hurricanes and tornados. We have developed and tested a wide range of I-Frame designs and sizes to meet the needs of windload codes, from inland tornado-prone areas such as Kansas City to windborne debris regions such as the Florida coast. All doors offered with windload ratings are tested in accordance with nationally recognized protocols and standards.

A door’s ability to withstand high velocity wind events is defined by design pressure, which is measured in pounds per square foot of force acting on the door. Note that wind resistant products must carry a design pressure (d.p.) rating verifiable by a third party.

In addition, we offer a custom wood garage door with impact rated glazing. This door carries both a Miami-Dade County Notice of Acceptance and Florida Building Code product approval. In addition, Designer Doors was recently awarded U.S. Patent 7,299,853 for this door design.
