Storm panels are used to protect the inside of buildings from damage caused by storms. Closeable shutters, mounted at the edge of building openings, have been used for centuries as protection against storms. Today's storm panels are demountable or movable, and rated for hurricane protection and flying debris. They are constructed of a variety of materials, such as plywood, aluminum, steel, plastic and fabric. They are affixed, when needed, to the outside of the building with screws or bolts and clips, or they can be installed as part of a track or motorized system. When not in use, storm panels should be properly stored. Storm panels are effective at minimizing damage; however, their use requires advanced planning prior to a storm.
