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.

  • Administrative buildings
  • Safe rooms and shelters

  • Anywhere you want advanced protection

Advanced Security and Protection

Keep people safe and your commercial property protected with doors rated for reliable protection under the most extreme conditions. Prepare for the next hurricane, withstand a heavy windstorm and stop the most determined criminals in their tracks with our security lines, including:

  • 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. 
  • 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. 
  • EntryDefender® doors: The EntryDefender security door provides the highest level of safety during a hurricane or sustained mob-style assault. These doors meet the Department of State standards to resist forced entry for five to 60 minutes of continuous attack, depending on the model. EntryDefender doors also feature unparalleled wind resistance, rated to withstand sustained winds up to 125 PSF, or in excess of 200mph. 


"We are very pleased with the performance of the Cornell doors. Throughout the area, doors are blown out everywhere and the building we just moved from was destroyed. Here, our $2.3 million of inventory was saved. Being satisfied with the Cornell doors is an understatement!"
