What is a hopper window?

A hopper window is a type of window that opens inward from the top by pivoting on horizontal hinges at the bottom of the frame. This allows the window to essentially "hop" open and closed, hence the name.

Hopper windows are commonly used in basements, bathrooms, and other areas where ventilation and security are important. Because they open inward, they provide excellent protection against rain and drafts when closed.

These windows are typically smaller in size and have a compact design, making them ideal for rooms with limited wall space. Hopper windows can be operated manually or with the help of a crank mechanism for easier opening and closing.

Overall, hopper windows are a practical and efficient option for adding light and ventilation to a space while maintaining security and energy efficiency.
