What is the operation of awning windows?

Awning windows are designed to swing outward from the bottom, creating an awning-like effect that allows for ventilation while keeping rain out. This unique operation is particularly useful in climates where rain is frequent, as the window can be opened without allowing water to enter the interior space. Because they are hinged at the top, opening them outward allows for airflow while also providing some shelter.

In contrast, the other options describe different types of window operations: sliding vertically is characteristic of sliding windows or double-hung windows, opening inward refers to casement windows or some types of hinged windows, and being fixed means the window is stationary and does not open at all, which is not applicable to awning windows. Understanding how awning windows operate is crucial for selecting the appropriate window type for specific building designs and climates.
