Wind Load Garage & Commercial Doors

During an extreme wind event, storm-driven debris can dent, deform or even penetrate residential and commercial doors. These products play a crucial role in protecting your home or business, especially if you live in a hurricane-prone or high-wind region. It's important to have a hurricane-rated garage door that can withstand flying debris driven by high-velocity hurricane winds to help minimize potential storm damage to your home. A wind-rated door can withstand flying debris driven by high-velocity hurricane winds to help minimize potential storm damage to your home. High wind events can cause un-reinforced garage doors to buckle, forcing the door out of the track causing catastrophic door failure which may cause an uncontrolled buildup of internal pressure that could result in damage to the roof and even the supporting wall panels. To be prepared for wind speeds that exceed 111 mph (Category 3 hurricane and above), you would need a wind load-rated or impact-resistant door to avoid catastrophic damage. It's important to check your local codes to find out the wind rating required in your area.

What Does Wind Load Rated Mean?

A wind load-rated garage door or commercial door from Wayne Dalton is a complete wind-resistive system for use in high-wind and hurricane-prone areas. A wind load-rated garage door is one where specifically designed reinforced hardware has been added to the door for increased strength and stability. This door system is then rigorously tested and approved in accordance with National, State, and local building-code standards.

Why Do I Need Wind Load Reinforcements?

The Federal Emergency Management Agency (FEMA) identified the loss of garage doors as one of the major factors contributing to hurricane storm damage in homes and about 80% of residential hurricane wind damage starts with wind entry through the garage door according to Federal Alliance for Safe Homes. The structural integrity of a building can be compromised if the wind forces cause the residential or commercial door to buckle during a hurricane or severe storm. With the appropriate configuration of heavy-duty reinforcements, Wayne Dalton’s wind load-rated doors can stand up to high wind pressures produced during extreme weather events, protecting your building and assets.

What Makes a Wind Load Rated Door?

wind safe logoWayne Dalton WindSafe® doors feature upgraded hardware to make them capable of withstanding strong windstorms. Depending on the wind load option selected, the upgraded hardware includes:

 

Residential Door Component

As a guideline, doors up to 10’ wide are strutted and doors over 10’
wide are either strutted or posted depending on the PS

Commercial Door Components – Including residential*

wind safe logoWayne Dalton doors labeled with the Impact™ logo have been approved for impact resistance to resist windborne debris caused by high winds during extreme weather. These tests include being able to stop the direct impact of a 9 lb. 2x4 board at 50 feet per second.

Impact Resistant Windows – An Added Feature

Windows made of clear, impact-resistant glass are compatible with a variety of decorative trim styles to complement all home designs and building aesthetics. Wayne Dalton impact resistant windows meet the Florida Building Code to withstand 350 foot-pounds of impact energy to make a door suitable for windborne debris regions (OR coastal regions prone to high winds.)

 

Protection Against Wind and Weather

Wayne Dalton created an exclusive line of innovative wind load-rated residential and commercial doors, fashioned to withstand nature’s power. These wind load options provide superior craftsmanship, durability, performance and additional protection against:

  • Hurricanes
  • High-Wind Damages
  • Internal and External Pressure Changes
  • Wind-Borne Debris

Wind Load Code Compliance

As a building component, residential and commercial doors may be required by local building codes to withstand certain positive and negative design pressures. The building department having authority in your area is the final determiner of the wind load requirements for your wind load-rated door. Homeowners and business owners should contact their local building professional, engineer or architect to understand their local code requirements and to identify the specific needs of their structure. In addition, local building codes may require a permit for the installation of the replacement of residential or commercial doors. A homeowners insurance policy may also have certain requirements.

Design Pressures by Model

Select Wayne Dalton door systems to meet or exceed the following building codes or approval agency standards: International Building Code (IBC) and International Residential Code (IRC), Florida Building Code (FBC), Texas Department of Insurance (TDI), Miami-Dade County approved. Our Impact doors have been approved for impact resistance and have been tested to stop the direct impact of a 9 lb. 2x4 board at 50 feet per second.
