Hopper Window
Definition and meaning of Hopper Window in real estate.
A hopper window is a single-sash window that is hinged at the bottom and opens inward from the top. It is commonly used in basements and small spaces to provide ventilation while maximizing security and preventing debris from falling inside.
In more detail
Because they swing inward, hopper windows are ideal for walls where outdoor space is limited, such as near walkways or driveways. The inward-tilting design allows air to flow downward, which helps circulate air in lower-level rooms that tend to be damp. Their small size and sturdy latches make them difficult for intruders to climb through, adding a layer of safety for homeowners.
Hopper windows are usually rectangular, wider than they are tall, and can be sealed tightly against weather elements when closed. They are frequently installed in concrete foundation walls of residential basements.
