What are the Differences Between Single Hung and Double Hung Windows? There is a very common misconception found among people that single and double-hung windows are the same as single and double pane windows. The single and double pane in the windows refers to the layers of glass used in each sash of a window. 

A single pane window has only one layer of glass in each sash; however, the double-pane windows consist of two layers of glass with an additional layer of gas in-between to add insulation.

Moreover, the double-hung windows describe how each sash moves. In single-hung windows, only the bottom sash can move up and down. In Double hung windows, there is a design built for each sash and both the upper and lower sash will move up and down and even tilt in and out.
