Hinged at the top, opening outward. Perfect for ventilation even during light rain.
Awning windows pivot on hinges at the top of the frame, with the bottom swinging outward. They're typically operated by a crank mechanism similar to casement windows, or by a simple push-out arm on smaller units. The outward opening design sheds water and provides weather protection while ventilating.
Operator failures are common since the crank mechanism must lift the weight of the sash. Stripped gears, worn arms, and broken cranks all prevent proper operation.
Hinge problems can cause the sash to sag or not close properly. The top-hinged design puts stress on the hinge hardware, especially on larger awning windows.
Seal failures allow water and air infiltration. The weatherstripping and compression seal can wear out, and the window may not close tightly enough for a proper seal.
Water intrusion can occur if the window doesn't close completely or if weatherstripping has failed. Since awning windows are often used in basements and areas prone to moisture, this is a significant concern.
Foggy glass indicates the sealed glass unit has failed and needs replacement.
Awning windows are commonly used in basements, bathrooms, and above fixed picture windows. Their ability to open slightly even in rain makes them popular for ventilation in areas where weather protection is important. When replacing or repairing, we consider the specific requirements of each application.
