Survive-a-Storm Shelters offers an array of options for above ground tornado shelters. They come “panelized” to be bolted together when installed, with welded seams to protect from rain, and even with a layer of bullet-resistant material, very similar to Kevlar. When you call us at 888-360-1492 to discuss your above ground tornado shelter purchase, one of the first questions our representatives will ask is, “How many people are you trying to protect?” We ask this early on, so that we can offer you the right size shelter for your needs. We build our “panelized” above ground tornado shelters in three standard sizes: 4×4, for up to 5 occupants, 6×6, for up to 12 occupants, and 8×8, for up to 16 occupants. Our fully welded above ground tornado shelter is 4×6 standard. It has several options including vents and an inward-swinging door, which makes it perfect for a closet shelter.The bullet-resistant model, called the Defender Vault, comes in 4×4, 6×6, and 8×8. It protects from all the common guns, and even some high caliber weapons. The Defender Vault also comes with a keypad lock option as well, so that any intruders won’t have much of a chance of getting in to you and your loved ones.
