An awning is a secondary covering attached to the exterior wall of a building. It is typically made of fabric or metal and is used to provide shade and protection from the elements, such as rain or sunlight. Awnings can be retractable or fixed, allowing for flexibility in use depending on weather conditions. Commonly found over windows, doors, and patios, awnings enhance outdoor spaces and improve energy efficiency by reducing heat gain inside buildings. They come in various styles, colors, and sizes, making them a popular choice for both residential and commercial properties.
