Single Hung Window Replacement

Single hung windows are one of the most common replacement window types for new home windows. They are a sash type window that open vertically. When most people think of standard windows in a home, this type of window comes to mind.

Single hung windows open vertically with their bottom window panel or lower sash moving up and down, and the upper sash remaining stationary. This means that when you open the window, the upper sash is covered on the inside.

Single Hung vs Double Hung Windows

Single hung windows are very similar to double-hung windows, the difference between these window types is that when using double hung both of the sashes operate and move. In single hung windows only one of the sashes moves making the average cost for window replacement a bit cheaper than most home windows or even a new double hung window installation cost.

Single Hung Window Installation

While single hung windows are relatively simple to install, if the frame of the window is not squared properly, it will not function as it should. You might still be able to open or close the window, but it will be significantly more difficult. If you have ever used a window that was hard to open or close, it is likely that the frame of the window was not square. Windows go out of square over time from a sagging foundation and other structural issues, but they can be put in that way as well if the replacement single hung window contractor working on the project fails to square the window frame properly. You will want to make sure that the installation of a new single hung window is done right the first time by a qualified installer.

Choosing Single Hung Windows

Simple, Easy Design

A single hung window is a popular sash type window that opens vertically. They do not have as many moving parts and are simpler to construct and are commonly found in homes all around the country.

Non-protruding Windows

Both single and double hung windows do not protrude during operation, unlike casement and awning windows. That means you can have them installed along a patio, on your deck and in other high-traffic locations without worrying about the windows coming out and getting in the way.

Effective Insulation

Since a single hung window only comes with a single moving sash, you just have to worry about keeping that moving sash sealed properly. The fixed sash will remain sealed effectively and will be as much work for you to keep weatherized throughout the year. You may have to add weather stripping and other weatherizers to the moving sash during the winter for maximum insulation, which could interfere with the functioning of your single hung windows.


Single hung windows are more economical than other window types. As the design does not have too many moving parts, they are cheaper in price and easily serviceable.

Can Only Open Half of the Window

Because of the way single hung windows work, you can only make use of half the window opening. So if you get a five foot window, you will be able to open up 2.5 feet of it. For that reason single hung windows limit the amount of air flow you can have through a home. They also have to be quite large in order to provide a large enough opening to be used as an emergency exit.
