Cornell maximum protection doors stand up to extreme forces, offering superior resistance to extreme wind loads. We manufacture custom closures offering protection against winds from the most severe storms, including tornadoes and hurricanes, and a level of security unmatched by traditional rolling doors.

While there's no such thing as a fully hurricane-proof roll-up garage door, Cornell offers many options that weather Mother Nature. Prepare for the next hurricane, tornado, or wind storm for locations like:

  • Administrative buildings
  • Safe rooms and shelters
  • Schools and public buildings
  • Secure and sensitive structures
  • Anywhere you want advanced protection

What Is a Hurricane-Rated Roll-Up Door?

A hurricane-rated door can withstand high amounts of impact. Due to their size, basic garage doors are vulnerable to storm winds and other driving forces. Manufacturers like Cornell solve this issue with reinforcements designed to resist those impacts.

Roll-up doors provide convenient operation, require low maintenance, and can offer insulation and sound-deadening qualities for extra benefits.

StormDefender® Doors

When the winds pick up, seal any opening with Cornell StormDefender security and storm doors, shutter-style closures designed to remain invisible until activated. With these doors, you can create a safe room anywhere, such as a cafeteria, gymnasium or any area offering enough room and protection for everyone. All our StormDefender doors are ICC 500/FEMA 361 rated for dependability in the event of a hurricane or tornado, with fire-rated models available

What Is a Wind-Rated Rolling Door?

Wind-rated rolling doors are those capable of handling the high winds associated with extreme weather events like hurricanes and tornadoes. These storm types can present positive and negative pressures, requiring a garage door that can withstand both. Generally speaking, the industry measures wind resistance in pounds per square foot (PSF).

Wind-Master® Doors

Cornell Wind-Master rolling service doors operate under wind loads up to 20PSF — over 85 mph — for reliable performance under intense weather conditions. These doors are suited for virtually any commercial or industrial application, with insulated models available to reduce sound transfer and improve climate control.

Storms aren't the only challenge businesses face today. Government structures, retail storefronts, and companies dealing with sensitive goods or data remain at risk from bad actors. Stop the most determined criminals in their tracks with our high-security protection doors.

What Is a High-Security Protection Door?
