This type of window has two sashes that slide vertically up and down in the frame. They can open wide from either the top or the bottom, but they remain inside the frame so they don’t protrude out to the exterior or interior of the house. On a single-hung window, only the bottom part of the window operates while the top part remains stationary. Photo courtesy of Marvin Windows and Doors
