DIFFERENCE BETWEEN SINGLE AND DOUBLE HUNG WINDOWS
The major difference between single and double hung windows is in how each window is operated. Single hung windows have a bottom panel or sash that moves vertically, while the upper sash or panel is fixed in place. These windows are fairly common in apartment buildings.
Double hung windows are different from single hung windows in that you have the ability to open both sashes. This means you can open both ends of your window up or down. In addition, both of the panels can be tilted down and in for convenient cleaning.
