What type of window is characterized by opening from the bottom?

An awning window is characterized by its unique design that allows it to open from the bottom, creating a hinged configuration at the top. This type of window typically opens outward, which is particularly advantageous for ventilation, as it allows air to flow in while providing shelter from rain or inclement weather. The top-hinged feature means that even when the window is open, rainwater is directed away from the interior, making it a practical choice for many climates.

The functionality of awning windows makes them suitable for locations where fresh air is desired without the risk of water entering the home. They are often used in combination with other window styles to enhance the aesthetic appeal and to maximize natural light and airflow in a space.

In contrast, other window types have different operational mechanisms. For example, casement windows typically open outward from the side, while double-hung windows slide vertically and bay windows are fixed structures that usually consist of multiple connected windows that extend outward from a building's facade. These differences highlight the distinctive features and benefits offered by awning windows in architectural design.
