What is characteristic of an awning window?

An awning window is designed with hinges located at the top of the window frame, which allows the bottom of the window to swing outward. This design is particularly advantageous as it creates an awning effect when opened. One of the key benefits of this type of window is that it can be opened even during inclement weather, such as rain. The angle of the opening helps prevent rainwater from entering the home while still allowing for ventilation.

This makes awning windows a practical choice for providing fresh air while protecting indoor spaces from the weather. The function of this window type aligns with the characteristic stated in the correct answer, making it clear why this is the most accurate description.
