Maximum Ventilation With A Hopper Window
A hopper window is hinged at the bottom. A hopper window in a house designed to open inward to a point completely perpendicular to the wall, allowing for maximum ventilation in basements or small spaces like bathrooms. The hopper window features a locking mechanism at the top. There is a small, lever-style handle that is used to open and shut the window that also fits into the locking mechanism for security. Depending on the size of the window, security features are important because of the fact that the window is often at or close to ground level, making them easily accessible for intruders. Replacement hopper windows are readily available from both dealers and home improvement stores. The window is considered to be very energy efficient and provides maximum function compared to other models designed for small openings. One of its disadvantages is limited privacy.
Window coverings such as blinds or curtains make the normal operation of a hopper window cumbersome, if not impossible. Alternatives to window coverings for a this style are privacy films and tinting. The hopper window accommodates a full window screen because the window opens inward, away from the screen. Casements include wood and vinyl, making them both decorative and practical for most all installations.
