Abstract: An improved above-ground storm shelter having sidewalls comprised of two panels, an outer panel and an inner panel, a door means for allowing ingress and egress and for remaining securely closed during a storm event, and a roof adapted to be affixed thereto, whereby sound of articles striking the sidewalls during a storm event is lessened, and the two panels provide enhanced structural integrity compared with a single panel of comparable thickness. The sidewalls may be manufactured in modular segments adapted to be joined together to form a desired size of shelter. Preferably, at least one segment has defined therein a ventilation port with a cover means for preventing projectiles from entering the shelter during a storm event while allowing equalization of pressure.
