What is a hopper vent?
In respect to this, how do I open the hopper on Windows?
Awning windows hinge at the top and push outward to open. When the window is open the glass pane creates a little roof over the opening. Hopper windows are similar, except they hinge at the bottom and can push outward or pull inward to open.
Just so, what do you call a window that opens upward?
A casement is a window that is attached to its frame by one or more hinges at the side. Casement windows are often held open using a casement stay. Windows hinged at the top are referred to as awning windows, and ones hinged at the bottom are called hoppers.
A hopper window is a small window that opens downward and inward. It is commonly installed as a bathroom or basement window. The upward tilt of the window glass pane blocks open dirt and debris from getting into your home. It usually can be opened with a crank or hinge.
