Function
-
Awning windows are hinged at the top and open outwards from the bottom, so that, from the exterior, they look like an awning. They may be installed as single large windows, or as a series of smaller windows, but are more commonly used in combination with other styles of window, or above a door. Awning windows were once common in older homes and industrial buildings, but are now used as an architectural feature or to provide additional ventilation.
Benefits
-
Because awnings windows open at the bottom, they may be opened during rain, without letting water in. This helps provide additional ventilation for a room. When used in combination with other windows, awning windows can add height and additional light, as well as provide improved air circulation. Because they open from the bottom, they are also a good choice for places with a reach, such as over a kitchen sink.

Disadvantages
-
Awning windows have a minimal opening and therefore often need to be combined with other types of window to provide adequate ventilation. Because awning windows open outwards, screens can only be fitted on the interior. Awning windows are also difficult to clean on the outside and may create an obstruction in some locations.
Materials
-
Awning windows are available in a variety of materials, including wood, vinyl, aluminum, fiberglass, and wood-clad. Aluminum windows are commonly used in industrial buildings because of their strength and durability, whereas wood or wood-clad are a popular choice for homes, as the wood gives a warm look and feel. Wood does not weather well and can be time-consuming to maintain, so combination windows are becoming a popular option. These windows have wood on the interior side, for warmth and architectural beauty, and vinyl or aluminum on the exterior, to provide weather resistance.
Extra Features
-
Originally, awning windows needed to be pushed open and propped, but modern windows offer a range of hardware including crank handles, friction glides, and locking mechanisms. Grilles may be added to windows to add architectural interest and match the style of the house, e.g., colonial, prairie, and Victorian. Many companies also offer customized grille patterns as well as options for screens and a range of glass suited to energy efficiency in various climates. Other features include corner guards and continuous hoods at the top of the window to prevent rainwater coming in.
