In this blog:
- The core difference is the sashes: A single-hung window has one movable sash (the bottom); a double-hung window has two movable sashes (the top and bottom).
- Double-hung windows offer more benefits: Both sashes tilt in and open, which matters most in bathrooms, kitchens and upper-floor rooms.
- Single-hung windows cost less upfront: Fewer moving parts means a lower price point, making them a practical choice where top-sash ventilation isn’t a priority.
Single-hung and double-hung windows are two of the most popular home window styles, differentiated mainly by one panel, or sash. Double-hung windows have sashes that move up and down, while single-hung windows have a fixed upper sash and the bottom sash only opens upward. Although they look very similar, these windows can differ in more ways than just operation. We’ll compare and discuss single-hung versus double-hung windows in depth so you can make the best choice for your home.

What Is A Single-Hung Window?
Single-hung windows have a fixed upper sash and movable lower sash. They’re called single-hung or occasionally single-sash due to the sole moving sash, but it’s a slight misnomer. Single-hung windows technically have two sashes, but only the lower one can be moved.
What Is A Double-Hung Window?
Double-hung or double-sash windows can be opened from either sash. Like single-hung windows, these windows have two sashes. However, both the top and bottom sashes open, giving double-hung windows more versatility.
5 Differences Between Single-Hung and Double-Hung Windows
Despite looking similar, single-hung and double-hung windows operate differently. Here are some of the main differences you’ll notice day-to-day.
Sash Operation
The key difference between single- and double-hung windows is that top sash. Single-hung windows have a fixed top sash, while double-hung windows can open from the top or bottom sash. With two movable sashes, double-hung windows offer more versatility that can be useful.
Ventilation & Airflow
Although both single-hung and double-hung windows can provide good ventilation, double-hung windows have the added advantage of allowing airflow from the top and bottom. This can come in handy in areas where added ventilation is essential, such as bathrooms and kitchens.
Cleaning & Maintenance
You can clean both single-hung and double-hung windows easily with your favorite household glass cleaner or a vinegar and water solution. Just spray and wipe with a lint-free cloth, and you’re done.
However, Window World’s double-hung windows have tilt-in functionality, allowing you to clean both sides of the pane from inside your home. This is a game-changer for windows on upper floors, and something single-hung windows cannot do. With single-hung windows, you’ll have to clean outside panes from your home’s exterior, which can be difficult or even dangerous.
Energy Efficiency
Historically, single-hung windows have been acknowledged as more airtight due to the fixed top sash. However, with modern construction and advanced weatherstripping in play, double-hung windows more than hold their own as energy-efficient powerhouses.
Window World takes pride in offering energy-efficient options made to reduce your monthly bills—take a look at the breakdown here.
Cost & Budget
When budgeting for home upgrades, it only makes sense to secure the best deal possible. Single-hung windows, with their simple design and fewer moving parts, are typically less costly. Double-hung windows contain more complex mechanisms that present a higher upfront cost. That being said, the added cost can be worth it for the lasting benefits and value.
Are Double-Hung Windows Worth It?
Yes, double-hung windows are absolutely worth any extra expense for their convenience and utility. There’s a reason double-hung windows are our most popular window style sold. You get the added benefits of easier cleaning and extra ventilation, both of which can prove invaluable in virtually any room, and especially on upper floors.
Single-hung windows are a great choice for budget-conscious homeowners, or for ground-floor use, where you can easily access the outside of the windows for cleaning. That being said, we’d still recommend double-hung as the better choice for most homes.
Single-Hung or Double-Hung Windows: Which Should You Choose?
Curious where double-hung or single-hung windows would best fit throughout your home? Let’s do a quick walkthrough of room-specific recommendations.
- Bathrooms and kitchens: Double-hung windows are the better choice for superior ventilation and moisture control.
- Living rooms: Double-hung windows allow superior air circulation where you need it most.
- Upper-floor rooms: Double-hung windows make the most sense for upper floors, since tilt-in sashes make cleaning far easier and safer.
- Ground-floor rooms, additions or budget-driven projects: Single-hung windows make sense in these use-cases, since easy outside access and lower cost offset the fixed top sash.

Frequently Asked Questions
What are double-hung and single-hung windows used for?
Double-hung and single-hung windows are ideal for homeowners who want a classic style, low maintenance and reliable ventilation. The easy-to-use design allows you to open your home to natural light and fresh air without extra effort.
Can a single-hung window be replaced with a double-hung window?
Yes, single-hung windows can be replaced with double-hung windows. Our professional installers tackle jobs like these every day. The full window, frame included, has to be replaced, however. You cannot take a single-hung window and make it double-hung without replacing the window entirely.
Do double-hung windows cost more than single-hung windows?
Generally speaking, yes, double-hung windows cost more than single-hung windows. This comes down to the more complex frame and internal hardware required for double-hung windows, since double-hung windows open at both sashes. However, the added ventilation and easier maintenance that these windows offer often makes the extra cost worth it.
