What is the difference between single-hung and double-hung windows?
The main difference between single-hung and double-hung windows is how they open. The top sash (glass panel) of a single-hung window cannot be opened (it’s “fixed”), so you can only open the window by lifting the bottom sash upward. Double-hung windows can also be opened from the bottom, plus you can slide the top sash downward, so you can open the top, bottom, or both.
The differences in how these two windows operate means they each have unique characteristics, which we’ll explain later. But before we get into those details, you should first understand what single-hung and double-hung windows have in common.
What do single-hung and double-hung windows have in common?
These window types feature two vertically stacked sashes that look basically the same. Here are some other things they have in common:
They both have a timeless aesthetic that’s perfect for traditional and modern classic homes—think farmhouse, colonial, craftsman, Cape Cod, and more.
They sit flush against the wall, which makes them perfect for patios, decks, and other places where windows that open outward would obstruct the space.
Both windows come in a variety of options, so you can find one that meets your needs in terms of aesthetics, performance, material type, and cost. Plus, both windows work whether you’re building a new home, remodeling, or replacing—there’s no wrong choice here!

When you might have trouble opening the top sash. If the window is oversized or mounted high up, you may be more likely to use only the bottom sash. Think carefully about the logistics of opening the window before choosing one over the other.
When You Might Want to Choose Double-Hung Windows?

When you’re picking windows for heavily used rooms: Bring in plenty of fresh air with these flexible windows. Since there are two sashes that can be opened at the same time, you can choose to open the top sash, the bottom sash, or both. In rooms with only one window, double-hung windows are a great choice because it allows you to exhaust the hot air that rises to the top of the room out the top opening, while cooler air can flow in through the bottom opening.
