Windows not only say a lot about your style, but they also add to the value of your home. When you look at the outside of a house, the windows are one of the first things that you notice.

Having the right style window adds to your home’s curb appeal and can even lower your energy bills. Plus, replacing old windows is one of the most valuable improvements you can make if you want to increase your ROI (return on investment).

If you’re planning on getting new windows and can’t decide between double-hung vs. single-hung, how do you know which style to pick?

Understanding the different window options on the market can help you make an informed decision. Learn about the difference between single-hung vs. double-hung windows here.

What’s the Difference Between Single-Hung vs. Double-Hung Windows?

Both window styles are vertical sliding and have an upper and lower sash. The sash is the lower panel on a window.

On single-hung windows, the upper sash doesn’t move because it’s fixed in place. The bottom sash moves vertically. Single-hung windows are often the default choice for new home construction, condos, office spaces, and apartments.

On double-hung windows, you can open either the top or bottom sash. This means you can adjust your window for optimal airflow and better ventilation.

Most window manufacturers, like Milgard windows, offer both single-hung and double-hung window styles.

So what’s the best choice between single-hung vs. double-hung?

Deciding which is best for you depends on your personal preferences and your budget. Both styles have their advantages and disadvantages, after all.

The Pros and Cons of Single-Hung

Many homeowners are perfectly happy with their single-hung windows. Since these are common in many homes, you’re likely familiar with this style already.

Here are the pros and cons of a single-hung window:

Pros

Single-hung windows remain popular mainly because they cost less. This style can be up to 20 percent cheaper than double-hung windows.

If you’re installing or replacing one window, the cost may not be a big issue. But replacing all the windows in an older home can get expensive.

At home, heat gain and heat loss through your windows account for 25 to 30 percent of heating and cooling use.

Since inefficient windows cause your energy bills to rise, many homeowners want to replace all their old windows as soon as possible. Single-hung windows may be a more cost-effective option.

Cons

Because single-hung windows only open from the bottom, you have limited airflow and ventilation options. This may not seem like a huge deal, but some rooms benefit from having better ventilation.

Moisture tends to build up in rooms like the bathroom and too much moisture can lead to mildew and mold growth. Single-hung windows only offer limited ventilation.

Another potential drawback is that this style can be harder to clean. If you live on a single level, this may not be an issue. But single-hung windows on upper floors can be difficult to reach and clean.

The Pros and Cons of Double-Hung

Double-hung windows may cost more than single-hung windows, but they have many benefits. For this reason, homeowners often prefer to install double-hung windows in their homes.

Here are the advantages and disadvantages of double-hung windows:

Pros

Double-hung windows offer more versatility when it comes to airflow. Both the top and bottom sash open and tilt on double-hung windows.

This can make all the difference if you want to get a nice cross-breeze going in your home. Double-hung windows also help ventilate areas prone to moisture buildup like the bathroom.

The ability to open and tilt both sashes makes this style easier to clean than the alternatives. This can make them a low-maintenance option for homeowners.

Plus, with double-hung windows increasing in popularity, there are now more styles and colors to choose from.

Cons

One drawback of the double-hung style is that it may need more maintenance. You may have to lubricate the tracks from time to time so it’s easy to open and slide your sashes.

There’s no doubt that energy-efficient windows can save you money on your energy bills. But to see those savings, you may need to replace all your windows at once. Replacing one or two won’t make much of a difference.

Replacing all the windows in your home with double-hung windows can get expensive. But if you have the budget, investing in double-hung windows causes savings to accrue over time.

Double-hung windows may also be more susceptible to air leaks or infiltration. Window seals degrade over time and with repeated use. You can’t seal double-hung windows with caulk like you can with single-hung windows.

One of the biggest factors to consider when buying new windows is the cost. Double-hung windows tend to cost more than the single-hung style.

What About Older Homes?

If you have an older home, the first thing you might want to upgrade is the windows. Drafty windows allow air to escape, raising your heating and cooling costs.

You have several options when it comes to fixing windows in an older home. You can repair old windows or replace them.

If you plan on replacing your old windows, consider custom-made windows. Custom windows are more likely to match the style and character of an older home.

When it comes to window style, single-hung windows may look more historically accurate. Still, it’s best to consult with a window professional who can walk you through the different options for an older home. Many double-hung styles can mimic the look of older windows.

Finding the Right Window Style for Your Home

When it comes to single-hung vs. double-hung windows, how do you know which style to choose?

Before picking a style, you must consider what you want to get out of your windows and how much you’re willing to spend. There are pros and cons to each, as seen in this comparative guide.

The ability to open both sashes is one reason many homeowners choose double-hung windows. This can increase ventilation and airflow in your home. They also may be easier to clean.

Single-hung windows cost less, so they may be ideal if you’re on a tight budget. The age of your home may also impact which type of window is best for you. If you’re undecided or have questions, speak with a window professional to go over your options.
