Hopper Window Details
A hopper window is hinged at the bottom of the window rather than at the top, and open inward rather than outward. The screen on the hopper window is on the outside. Hoppers do not offer the same protection against rain as awnings do while open.
Windows with compression seals allow about half as much air leakage as double-hung and horizontal sliding windows with sliding seals. In other words, hinged windows generally have lower air leakage rates than sliding windows because the sash presses against the frame when closed.
Most often, hopper windows are used in small bathrooms and basements. They are also found above doors and other types of windows and are then referred to as transoms.
Advantages of Hopper Windows
- Good Ventilation. Awning windows can be placed higher in walls than many other types of windows. When placed high, awning windows can provide natural light and ventilation, without compromising privacy. High placement also allows for maximum wall space for design aspects such as art and furniture placement.
- Weather-tight construction, good choice in damp climates.Awning windows can protect your home against moisture, even when they’re open during a rainstorm. Because of the way awning windows are constructed, they allow for nearly 100 percent of viable ventilation, without the threat of water seeping into the home. Awning windows also offer a superior seal against air pass through.
- Attractive, contemporary look. Newer awning windows use friction hinges at either end of the top edge. This allows the bottom edge of the awning window to swing open, creating a fresh, contemporary look.
Disadvantages of Awning Windows
- Unsafe for high traffic areas of the exterior home. Awning windows have open projecting sashes. If an awning window sits overlooking sidewalks, decks, porches, or terraces, someone can easily collide with the windows’ jutting sashes.
- Require frequent washing. Open sashes on awning windows are exposed. The open slashes slant as well, so they can become dirty faster than other types of windows and require regular washing.
- Escape may be difficult. Screens and storm windows are mounted on the inside of awning windows. This could make a fast escape difficult in case of a fire or other dangerous situation. However, the construction of awning windows makes entry quite difficult as well.
