Single Hung Vs Double Hung Windows

Single-hung windows and double-hung windows are two of the most popular choices for residential homes, but how do the two options compare? Let’s take a peek at the similarities and differences between single-hung and double-hung windows so you can make the perfect choice for your home.

What is a Single-Hung Window?

What is a Single-Hung Window?

Single-hung windows are also sometimes called “single sash windows.” A window sash is the part of a window that holds the glass in place. Despite its name, a single-hung window has two sashes, but only one is operational and movable.

In single-hung windows, the top sash is fixed in place and doesn’t move, but the bottom part generally slides up and down to open and close the window.

What is a Double-Hung Window?

What is a Double-Hung Window?

Like a single-hung window, most double-hung windows have two sashes. They’re also sometimes called “double sash windows.” However, unlike a single-hung window, in a double-hung window, both sides are operational. The top and the bottom sash can both slide open and closed.

Comparing Single-Hung Windows to Double-Hung Windows

So, how do these two types stack up in a head-to-head comparison?


As we already discussed, a single-hung window only opens on the bottom sash, whereas a double-hung window opens on both the bottom and top. In addition to the movable sashes, the operational sashes also tilt inside the home for cleaning purposes.



The cleaning process for single and double-hung windows is relatively similar. For both windows, you’ll simply spray the glass with a window cleaner and wipe it with a lint-free or microfiber cloth.

The difference is that with double-hung windows, both sashes tilt towards the inside of the home, making them super easy to clean. In other words, you can clean the inside and outside of both sashes from inside your home.

With a single-hung window, you can clean the operational bottom sash inside the home. 

However, to clean the outside of the top sash, you’ll need to go outside. As a result, ongoing maintenance is much more difficult with single-hung windows.


Single-hung and double-hung windows both have two sashes. Consequently, they have pretty similar appearances. The real difference between these two window options is their operational and functional differences.

However, double-hung windows tend to have more style options than single-hung windows, making them the go-to choice for the homeowners who want a little extra style on their home’s windows.



Double-hung windows enable maximum ventilation and circulation. When you open both sashes, you get optimum circulation. Since hot air rises, cool air flows into the home through the bottom sash, while warmer air flows out of the top sash – perfect for getting some natural air conditioning on those nice breezy days.

Conversely, single-hung windows only allow air to flow in and out of the bottom sash. So while you’ll still get some cool air, it won’t be as ventilating or effective as the airflow of a double-hung window.


Installation techniques vary by manufacturer and project for both single and double-hung windows. However, in general, single-hung windows are often more straightforward to install.
