Which window is similar to an awning window but is hinged at the bottom?

The window that is similar to an awning window but is hinged at the bottom is a hopper window. This type of window opens inward by tilting at the top, allowing for ventilation while providing protection from the elements, particularly rain. The bottom hinge allows it to operate similarly to an awning window, but the key difference lies in its design and function.

Hopper windows are commonly used in areas where space is limited or when the window needs to open inward, which makes them ideal for basement ventilation or in homes where exterior space is constrained. The design allows for easy cleaning and maintenance, as well as optimal airflow when opened. Understanding this functionality is crucial for selecting the appropriate window type for specific building needs.
