What is a hopper window?

A hopper window is characterized by its unique design where it is hinged at the bottom and opens inward. This allows the top of the window to swing into the room, making it ideal for ventilation while minimizing the risk of rain entering the space. This inward-opening mechanism also provides practical advantages, such as ease of cleaning and the ability to safely keep the window open in inclement weather.

This design is particularly effective in basements or areas where privacy is crucial since it can be installed high on the wall, allowing for ventilation without compromising security or sight lines. Understanding the specific function and characteristics of a hopper window is important for recognizing its applications in building design and effective ventilation strategies.
