The Difference Between Single-Hung Windows and Double-Hung Windows: Insights from a Replacement Windows Company in Lake Zurich, Illinois

If you’re looking for the simplest and most basic window available for your home, it is the hung window. Hung windows are taller than they are wide, and they open in an up-down manner. They can be installed in all types of rooms throughout the home, and they provide a decent level of visibility, sunlight, and ventilation variation.

What you might not realize, however, is that there are two types of hung windows available: single-hung windows and double-hung windows. Are you interested in learning about the differences between the two? Below, this replacement windows company in Lake Zurich, Illinois is going to explain their main differences and similarities.

Functional Features

As was noted above, hung windows are taller than they are wide. This is true of both single and double-hung windows. When in a closed position, these windows look identical to one another.

This changes once the windows are opened. Why? Because, while single-hung windows possess a single moving sash, double-hung windows possess two moving sashes.

What this means is that, with the single hung window, you can only move the bottom pane on the window. It slides up and down to different extents, going no higher than the middle of the window.

With double-hung windows, on the other hand, both panes can slide up and down. Therefore, there is more flexibility. You can leave the top sash all the way up while moving the bottom sash to the middle, for example. You can also do the opposite — you can move both sashes toward the middle of the window frame, leaving open spaces on both the top and bottom.


In terms of the amount of sunlight allowed in, single-hung and double-hung windows are identical. They possess the same shape, and therefore, allow in the same amount of sunlight. If ample sunlight is your top priority, your local Lake Zurich, Illinois replacement windows contractor will be happy to show you multiple options.


When it comes to visibility, there is a bit of variation between single-hung and double hung windows. It all comes down to the placement of the individual sashes.

With single-hung windows, there will always be a horizontal panel passing through the middle of the window frame. With double-hung windows, because both sashes can move, this horizontal panel can move up and down the frame. Therefore, double-hung windows offer more variation for visibility.


Both types of windows can provide ample ventilation in Lake Zurich, Illinois. One thing to note, however, is that double-hung windows provide increased ventilation possibilities. This is, again, because they possess two moving sashes.

Whereas a single-hung window can only allow ventilation through its bottom half, double-hung windows can allow ventilation through both their bottoms and tops. As such, double-hung windows allow for more ventilation variation overall.

Ease of Cleaning

Perhaps the biggest difference between single-hung and double-hung windows is in their ease of cleaning. Put simply, double-hung windows are easier to clean. This is because both their interior and exterior sides can be cleaned from the comfort of the home. All you’ll have to do is move the sashes as needed, and you’ll be able to reach the other side of the window.

This isn’t generally true of single-hung windows, whose exteriors usually need to be cleaned from the outside of the house. It’s simply too difficult to reach around the window with only a single moving sash.
