An awning window is a type of window that is hinged at the top and opens outward from the bottom. This design allows for ventilation even during rainy weather, as the window's angle helps to keep rain out. The awning window is often used in combination with other window types or as part of a larger architectural design to enhance airflow and natural light while providing some shelter from the elements.

Key features of awning windows include:

1. Top-Hinged Operation: They open outward from the bottom, typically with a crank mechanism for easy operation.

2. Ventilation: They provide good airflow while protecting the interior from rain.

3. Energy Efficiency: Many modern awning windows come with energy-efficient glazing options to help improve insulation.

4. Design Versatility: They can be used alone or combined with other windows for aesthetic and functional purposes.

Awning windows are popular in areas where both light and ventilation are desired but protection from rain is also important. They are commonly found in bathrooms, kitchens, and other spaces where maintaining privacy while allowing fresh air is a priority.
