An awning is a secondary covering attached to the exterior wall of a building. It is typically composed of canvas or acrylic cloth that is stretched tightly over a light structure of aluminum, iron or steel, and possibly wood. The configuration of this structure is something of a truss, space frame or planar frame. The location of an awning on a building, is either above a window, a door, above the area along a sidewalk or above a patio. With the addition of columns an awning is able to extend enough from a building to line an entryway, as in the case of an entrance to a hotel. Restaurants often use awnings broad enough to cover substantial outdoor area for outdoor dining, parties, or reception. In commercial buildings such as these, an awning is often painted with information as to the name, business, and address, thus acting as a sign or billboard in addition to providing shade from the sun, break from steep winds and dryness from rain or snow. | |||||||||||||||
