I have a basement / interior bathroom / etc. Why do I need a storm shelter?Answer:
Tornadoes can be strong enough to destroy houses, and tear up even the strongest floor framing. Flying debris can even punch through wood beams in excess of eight inches thick. Survive-a-Storm residential storm shelters have been tested to withstand an EF5 tornado, and have been manufactured to be in compliance with FEMA 320 standards.
