What Are the Differences Between Single Hung and Double Hung Replacement Windows?

The terminology used in the window industry can be confusing for the average homeowner. And while it’s not necessary for a homeowner to know all the terms related to replacement windows, it can be helpful to understand some of the basics, such as the features of the various styles of replacement windows and doors. On the BM Windows website, we’ve put together some helpful pages that go into great detail about the various styles of windows and doors we sell at our San Diego replacement window company, but if you’re like most of our customers, you probably still have questions about what styles of windows will work best in your specific home.

A common question we get is “What are the differences between single hung and double hung windows?” These two types of windows look virtually identical. They are both vertically oriented windows that have two glass panels (or sashes)—one on top of the other. However, there are some important differences to understand.

Operation

The main difference between single hung and double hung windows is in their operation. In a single hung window, only the bottom sash is operable. It has the ability to slide up to allow in fresh air. On a double hung window, both sashes are operable. You could slide the lower sash up, or the upper sash down. Opening the top sash is a great option when you want to let out some of the hot air that has accumulated in a room.

Ease of Cleaning

Another great feature in double hung windows is the fact that they have tilt-in sashes. Each of the window panels can be tilted into the room so the outside glass can be cleaned from the inside. This is great for upstairs windows that are difficult to clean or others around the home that are hard to access.

Cost

Because of the increased functionality, as well as the additional screen behind the second operable sash, double hung windows will cost more than single hung windows in the same manufacturing line.

There are a couple of reasons why someone might decide to pay extra for a double hung window. Most often, they do so because they like the ability to easily clean the windows from the inside and let out the warm air from a room, as mentioned above. However, some homeowners like the option to be able to open the top sash because they have pets (especially cats) who like to sit near their windows. When the window is open, the screen is exposed, and their pets tend to damage the screen with their claws. With the option to open the top sash, they can still let in the fresh air, but their pets won’t be able to damage their screens.
