Hopper Windows
Hopper Window is the term for a window we have all seen many times, but many of us never knew its name. Typically utilized in basement applications, they are like a casement window that is hinged at the bottom and tilts open at the top, instead of the side. The only difference in how the hopper window operates is that it opens in, instead of out. The screen on the hopper window is on the outside.
A similar style of window is the awning window, which is hinged at the top and tilts open at the bottom, somewhat like a fabric awning. Because the awning window opens outward, the screen is on the inside.
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. Like awning and casement windows, hopper windows are energy efficient. The compression seal of these windows keeps heat/air conditioning in, and the elements out.
The main benefit of hopper windows is that there are no sharp corners hanging down to whack you in the head, and it helps prevent leaves, dust, and trash that might be blown along the ground from blowing right into your basement.
Another benefit of hoppers, like casement windows, the entire window area can be opened, while sliders are limited to less than half of the window area.
You may also have seen hopper or awning windows in old movies or in older buildings that are built over a door. The term for this type of window application is a transom window. Transom windows were typically utilized in hotel and office rooms before air conditioning became commonplace.
