6 Types of Windows

Double-Hung Windows

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

Casement Windows

These hinged windows operate by a turn of a crank in an operating mechanism. They can be hinged on the left or the right to open outward. Photo courtesy of Marvin Windows

Awning Windows

Hinged at the top, awning windows open outward to let in air from the left or right and the bottom. They can be installed above, below or alongside a stationary or operating window. Photo courtesy of Marvin Windows

Transom Window

A narrow window that can be either operating to let in air or non-operating (stationary) and mounted above a door or window to let in more light. Photo courtesy of Marvin Windows

Slider Windows

Gliding along a track, sliding windows have at least one operating window that slides horizontally over or past the other window. They are most often used in modern- or contemporary-style houses. Photo courtesy of Jeld Wen Windows and Doors
