Why is there a need for tornado safe rooms?
Tornadoes are rated on a scale of EF0 to EF5. The scale ranges from 65-85 mph winds during an EF0 tornado to over 200 mph winds during an F5 event. Typically, the average home is built to withstand around 70 mph winds. In areas prone to tornadoes and hurricanes, local building codes can mandate increased standards to help prevent damage and loss of life.
One of the most devastating tornadoes had wind speeds clocked at 318 mph. But the wind speed alone does not cause safety concerns and damage. It also created deadly flying projectiles as well as positive and negative wind pressure. The wind forces cause roofs to lift off and buildings to separate from foundations while the impact of flying debris can penetrate metal at those speeds.
Installing a storm safe room or tornado safe room
Building a tornado room involves sturdier walls, roof structures and tornado safe room doors. The roof must be able to transfer wind loads to the walls and the walls to the ground or foundation. This did not allow many opening and the ones that were included required hurricane doors or tornado doors installed. Early designs and implementations involved heavy swinging safe room doors that needed to be manually closed and latched shut. If the doors could not be closed properly, the storm safe room’s integrity could be compromised. Self-shutting hurricane doors and safe room doors meant large cumbersome structures and often still had to be latched. Most buildings ended up with a safe room that was dark, claustrophobic and dungeon like. This made it hard for architects and designers to make the room function for other practical uses.
StormDefender™ - Built for Protection
The StormDefender door is big on security and on design. How? By being invisible until called into service. The StormDefender safe room door is engineered with sleek construction that can be embedded into precast concrete making it virtually undetectable. Now you can have safe room doors that are hidden above a ceiling or in a soffit that allow more design freedom. A single StormDefender tornado door can protect multiple openings or windows to maximize designs with natural lights. Now architects and designers have the freedom to incorporate a tornado room into a building’s design that is more open and airy, especially for safe rooms in schools, like cafeterias, classrooms or gymnasiums.
A more open design does not mean decreased safety, in fact just the opposite. StormDefender features our award-winning AlarmGard system with operation, so when a severe storm event is imminent, it will deploy automatically. Our patent pending the storm door’s curtain from pulling out of the guide which eliminates the need to manually latch or lock the tornado door once closed. This can free valuable time and manpower to make sure everyone is evacuated into the storm safe room. After any weather triggering event, the safe room door can simply disappear back into the structure.
StormDefender™ is ICC 500 and FEMA 361 Certified
Now you can turn space into an ICC 500/FEMA 361 rated safe room to protect occupants from harsh winds and deadly projectiles. Available in both fire–rated and non-fire-rated models, the StormDefender has been tested and certified to stringent ICC 500-2014 and FEMA P-361, third edition code standards. The StormDefender safe room door is tested to withstand high-speed projectiles leaving nothing but a dent less than 3”. Along with the impact test, the StormDefender held effortlessly when exposed to wind pressure of 300 positive and negative pressure. This door is built to protect any opening through two of Mother Nature’s most dangerous natural disasters.
