Awning Windows are single-panel windows that are hinged along the top and can be opened by turning a handle. When opened,
the panel tilts outward and allows air in from the left, right and bottom. Awning Windows are often installed above, below or
alongside a fixed (non-operable) or operating window, but can also be used as a clerestory (a window near the top of a wall) to let
hot air escape. - See more at: http://www.pgtindustries.com/products/windows/all?type_style=32#sthash.yaLEwl97.dpuf
