Tornado resistant openings are designed to protect occupants during short periods of high-velocity winds. Hurricane resistant openings are designed to withstand storm conditions for long periods of time. The primary purpose is to not only prevent debris and wind from penetrating the assembly but also to maintain functionality after the storm.

Von Duprin understands the guidelines, standards, and codes of the strictest agencies and councils such as Federal Emergency Management Agency (FEMA), International Code Council (ICC), Florida Building Code (FBC) as well as the American Society for Testing and Materials (ASTM), and American National Standards Institute (ANSI) and has developed a portfolio accordingly.
