You can open both sashes on a double-hung window.
Double-hung windows tend to have a higher price tag.
Single-hung windows tend to be more efficient.
Double-hung windows have the benefit of being easy to clean.
The type of window you select for your home will depend on your desired aesthetic, functionality, and budget. Single-hung and double-hung windows are two of the most popular and widely available designs. While they have many similarities, understanding the key differences between single-hung vs. double-hung will help you decide which is a better fit for your home.
Single-Hung vs. Double-Hung Windows: Key Differences
The main difference between single-hung and double-hung windows is right in the name. Single-hung windows feature a single movable sash on the bottom of the window and one fixed sash on the top. In other words, you can pull the bottom half of the window upwards to open it, but the top panel stays put.
On a double-hung window, both the top and bottom sashes move, allowing you to open one or both at the same time. Both varieties come in the same standard window sizes and can fit in a range of window frame styles, such as vinyl or aluminum.
While single-hung windows cost less, they provide less ventilation and flexibility than double-hung designs. And while cleaning a single-hung window is a bit of a headache, repairing a double-hung window is a tad more complex.

What Is a Single-Hung Window?
A single-hung window is a window with a top sash that is fixed and a bottom sash that is operable, meaning you can open it up to let in fresh air. There are benefits to this type of window, particularly the cost and efficiency benefits, but it also comes with some drawbacks.
Pros | Cons |
---|---|
Lower Cost | Less ventilation |
Historic charm | Hard to clean |
More efficient | Less versatile |
Best For:
Budget-friendly windows
Historic homes
Colder climates
Pros
Single-hung windows have been around since at least the 1670s, making them one of the most common window types. They’ve been popular for centuries for many reasons, including:
Lower upfront cost: Single-hung windows cost about $100 to $400 each.
More efficient: With a fixed upper sash, these windows have less risk of a faulty seal at the top of the window.
Ideal for historic homes: Because single-hung windows have been around for so long, they are a common choice for homeowners restoring older homes.
Cons
There’s a lot to love about single-hung windows, but they do have some drawbacks to keep in mind when choosing single-hung vs. double-hung windows.
Difficult maintenance: Because the upper sash is fixed, single-hung windows require you to be inside to clean parts of the window and outside to address the exterior glass.
Less ventilation: These windows will bring in plenty of fresh air, but they lack the double moving sashes that double-hung windows have that allow more ventilation.
What Is a Double-Hung Window?
If you’ve ever opened the bottom of a window to let in cool air and then popped open the top to release warm air on a breezy summer day, then you’ve already experienced a major benefit of double-hung windows. These windows, with their two moving sashes, have many other benefits as well, but they aren’t without some cons to consider.
Pros | Cons |
---|---|
Better ventilation | Costs more upfront |
Safer for pets and kids | Harder to insulate |
Customizable | Trickier repairs |
Best For:
Maximizing ventilation
Homes with pets and children
Double- or triple-paned windows
Pros
The double-moving sashes give double-hung windows several unique benefits, including:
More ventilation: You can open both the upper and lower sash to let in cool air while encouraging warm air to flow outside.
Customization: Double-hung windows come with extensive upgrade options, so you can customize the frame and the panes for each sash.
Easy to clean: Double-hung window sashes can tilt in toward the house, so they are easier to clean, even for windows on upper floors — no ladder required.
Cons
With all the extra customizations and additional moving parts, double-hung windows come with some drawbacks to keep in mind before making a purchase.
Higher upfront cost: Double-hung windows have a higher cost than single-hung. These windows cost about $150 to $650 per window.
Less efficient: The more operable parts on a double-hung window, plus the moving upper sash, mean air may be more likely to leak through shut windows.
Single-Hung Windows vs. Double-Hung Windows
Either single-hung or double-hung windows would be a great addition to any home, but you’ll need to weigh their differences to determine which would be the better fit for your household. For example, homes with young kids or curious pets may prefer double-hung windows, so you can open the top sash while leaving the bottom locked for safety. People living in historic homes might opt for single-hung windows as their Victorian windows to match the style of the house.
Appearance: Tie
Both single-hung windows and double-hung windows come in a wide variety of styles, with different frame options to suit your style. Each of their pros and cons mostly stems from the way these windows function rather than what they look like.
Options and Customizations: Double-Hung Windows
While both window options may be attractive, you may find it easier to customize the look of your double-hung windows. Because these windows have more moving parts, there are more parts to choose from to achieve the look you want for your home.
Ventilation: Double-hung windows
Because both sashes open on double-hung windows, they promote better airflow compared to single-hung windows. You’ll still be able to bring in a nice, cool breeze with single-hung windows, but double-hung windows are great for pushing warm air out of the open upper sash while bringing cool air in below. That’s why double-hung windows may be a great choice for your kitchen windows.
Efficiency: Single-Hung Windows
When considering single-hung windows vs. double-hung windows, single-hung windows tend to be more efficient. With more stationary parts, there are fewer risks of air leaks. However, you can buy energy-efficient versions of either window. Both types may offer low-E coatings or double- or triple-pane glass for better insulation.
Price: Single-Hung Windows
Single-hung windows have fewer operable parts and tend to be lighter in weight, so they have a lower cost. Single-hung windows cost about $100 to $400 each, while double-hung windows cost $150 to $650 per window. While cost is certainly not the only factor in a window buying guide, surprise fees are more likely to pop up the more complex the window design.
Ease of Installation: Single-Hung Windows
Again, because the single-hung windows are lighter in weight and have less parts that move, they tend to be easier to install. But in reality, any kind of window can be difficult to install, especially if you need to create a new window opening or enlarge an existing window. If that’s the case for you, it’s best to hire a window installation company near you to safely install your single- or double-hung windows.
Ease of Repair: Double-Hung Windows
Because you can move and tilt the two window sashes, you may find it easier to make repairs to double-hung windows. Just keep in mind that while repairs may be easier, they could also be more frequent. That’s because with more parts, especially moving parts, there are more opportunities for things to break.
Maintenance: Double-Hung Windows
Cleaning and maintaining double-hung windows is pretty breezy. Just tilt in the frames to clean the exterior glass, and you’re one step closer to finishing your chore list. That makes it easy and safe to clean these windows, especially for windows on a second or third story.
Safety: Tie
There are some safety concerns to keep in mind for both single-hung and double-hung windows. Double-hung windows are great for households with young kids or pets because the bottom sash can be locked into place while you can still open the upper sash for fresh air.
On the other hand, double-hung windows can be less secure if you aren’t careful. You have to remember to lock both sashes into place, whether they are open or closed. You don’t want a sash falling shut, nor do you want someone to break into your home because you forget to lock the upper sash.
