Awning windows are very much similar to casements. They share the same functionality and energy-saving features as casement windows. Awning windows open out from the bottom allowing air to circulate freely into the home providing effective ventilation while shielding your interior from rain. Awning windows are a dramatic statement of grace and comfort in modern architecture. They are very popular choice for a bathroom, as a stand-alone piece or with a set of windows. Awning Windows are available in different styles, such as single, stacked or side-by-side and can be matched effectively with picture windows.
