Technically we cannot guarantee that our storm doors are tornado proof. However in the devastating Hesston, Kansas tornado in 2012 the manufacturer helped clean up the rubble caused in this destructive storm. In the rubble they found two of Humphrey's doors that were reinstalled in the new house after replacing the glass and screen. The kick panel and master frame were good as new, not bent or warped from the heavy winds.
