Door protects from projectiles

CornellCookson Inc.’s StormDefender Door is a rolling steel door for safe room protection from tornados and hurricanes. It provides protection from projectiles and wind pressure to 250 psf. The StormDefender Door can be installed right into precast concrete, embedding it into the infrastructure of a building. It has a release device that allows it to close without loss of door spring tension, which provides maximum protection. The rolling door is tested and certified to ICC500-2014 and FEMA P-361 standards. The fire-rated version meets UL10B and UL1784 standards.
