What type of window is hinged at the top and swings out at the bottom for ventilation?

The window that is hinged at the top and swings out at the bottom for ventilation is known as an awning window. This design allows for opening the window while still providing protection from rain, as the top hinge keeps the opening covered when the window is swung out. Awning windows are often installed higher on walls to allow for ventilation without compromising privacy, making them versatile for various building designs.

In contrast, a hopper window, which is hinged at the bottom and swings in at the top, is designed for downward ventilation and is typically used in basements. A jalousie window consists of a series of narrow slats or louvers that can be opened or closed for airflow but does not swing at the bottom like an awning. A casement window, on the other hand, is hinged on the side and opens outward, which differentiates it from the awning style. Understanding these distinctions helps clarify the operational differences and functional purposes of these various window types.
