Above Ground or Underground Shelter?

Above Ground or Underground Shelter?

FEMA (Federal Emergency Management Agency) paid Texas Tech’s Wind Science & Engineering Research Center to design and engineer the above ground safe room to withstand an EF-5 rated tornado. One of the reasons for this was the number of injuries reported when people were forced to run into the storm to reach their underground shelter.

StormSafeRooms passed the Texas Tech EF-5 test on July 25, 2001. A link to the copy of our EF-5 test certificate letter is located at the bottom of our web page. The test requires a shelter to resist a 15-lb. 2×4 missile propelled by a 250 mph ground speed tornado. On our testimonials page, you will read a statement in which a family who survived the 2011 Joplin tornado in one of our safe rooms tell how the tornado drove 2x4s through the walls of their home. They moved in with their daughter until their home could be replaced and had us move that same storm room to their daughter’s home. Flying debris had scoured almost all the paint from the shelter while the family inside safely rode out the storm, but there was not a dent in the StormSafeRoom shelter. When their new home was finished, they purchased another safe room from us, and their son has also purchased one of our safe rooms.

In a demonstration at the Tulsa Home and Garden Show in 2000, we dropped a 1989 Lincoln Continental 4-door sedan 30 feet from a crane onto one of our safe rooms. As you can see from the photos below, this demolished the car without putting a dent in the safe room.
