Double Hung vs Single Hung Differences

Certain window styles are movable. These include casements, awnings, single-hungs, double-hungs, and sliders. The differences between the movable styles is HOW they open and close. Casements crank out, sliders slide horizontally, and awnings open out from the bottom (kinda like a doggie door). The other option apart from movable windows is "un-movable" - these are often called fixed frame or sometimes called picture windows. These unmovable options simply don't open.

Single Hung Windows (or SHWs) have one movable part - the lower sash. When this lower sash is opened, it allows for breezes to enter the window. When it is closed, the window is then sealed shut from air entering.

Double Hung Windows (or DHWs) have two movable sashes, one at the top and one at the bottom. This provides more options for ventilation.

And that, in a nutshell is the only real difference between these two window styles.

Double Hung vs Single Hung Advantages

In the past, SHWs were often considered cheap replacement windows, which, in many cases, they were. However, this was only because window companies cut all kinds of corners during the manufacturing process. Today, this is no longer the case. Today, you need to look at the brand, the model, and the performance data to know whether a DHW or a SHW is a quality product or not.
