Replacing Single Hung Windows
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.
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.
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.
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. This could interfere with the functioning of your single hung windows.
Note that 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.
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.
Single Hung vs Double Hung Windows
A common question from homeowners is: What is the difference between single hung vs double hung windows? Single hung windows are very similar to double-hung windows, but the difference between these window types is that for double hung windows, both of the sashes operate and move. With single hung windows, only one of the sashes moves, making the average cost for window replacement a bit cheaper than most home windows.

Proper Installation for Single Hung Windows
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 may still be able to open or close the window, but it will be significantly more difficult.
Windows go out of square over time from a sagging foundation and other structural issues. However, it can also mean the window contractor improperly squared the frame during installation. 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.
