An awning or overhang is a secondary covering attached to the exterior wall of a building. An awning is a type of supplemental roof or cover that helps control intense sun exposure and heat that occurs both indoors and outdoors. Awnings can be stationary or retractable and made of materials like aluminum, cloth, vinyl, or wood. They also cut down on home energy costs by decreasing the need for air conditioning. The location of an awning on a building may be above a window, a door, or above the area along a sidewalk. In commercial buildings, an awning is often painted with information as to the name, business, and address, thus acting as a sign or billboard as well as providing shade, breaking strong winds, and protecting from rain or snow. In areas with wintry weather, most awnings do not have to be taken down at the end of the summer – they can remain retracted against the building all winter long, or be designed and built for those conditions. For balconies, ground-floor positions and walkways, Automatic Awnings are perfect for privacy, sun protection and light control. Fitting closely to the frame, Automatic Awnings are hand-operated and the self-locking arms slide along vertical rails. In strong winds, Automatic Awnings respond by retracting to protect the fabric against weather damage.
