What Exactly is a Double Hung Window?

A double hung window is a classic window with a simple, smart design. It has two separate window panels (called sashes) that slide up and down inside the frame.

You can open the bottom sash by sliding it up, or you can open the top sash by sliding it down. You can even open both at the same time. This simple feature gives you more control over your space than a standard window.
