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 high wind events. We have developed and tested a variety of Timbercraft doors for windload capabilities. 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.

The following chart summarizes the windload rated doors currently available in our Timbercraft overhead door product line. Please contact your Territory Manager or our Engineering Department if you have a windload requirement that does not fall within this spectrum. Our I-Frame door also meets additional windload requirements.
