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

When you’re shopping for new windows to install in your home, you’ll notice that two of the most common types include single-hung and double-hung varieties. While these types of windows are like one another, some notable differences may play a role in your purchasing decision.

What Are Single-Hung Windows?

Single-hung windows consist of two parts. The lower sash can slide up and down, while the upper portion is fixed in place. When you slide the lower sash upwards, you can properly ventilate your home.

What Are Double-Hung Windows?

Double-hung windows have two parts that can slide up and down. Neither sash is fixed, which means that both can provide ventilation to your home. If you open both sashes at the same time, warm air will leave your home from the top portion. Cool air will come in through the lower sash. Double-hung windows are often used in two-story homes.

How Single-Hung and Double-Hung Windows Differ

Because of how these windows function, there are clear differences regarding their cleaning requirements, energy efficiency, and installation.

Cleaning Requirements

Whether you install single-hung or double-hung windows, it’s a good idea to clean them regularly. Keep in mind that not every single-hung window is the same. Some of these windows include tilting functionality, which means that you can tilt the lower sash inward to clean its exterior. Since the top sash is fixed in a single-hung window, it needs to be cleaned from the inside and outside. All double-hung windows are outfitted with latches on each sash, which means that both parts can be tilted inwards for easy cleaning.

Installation Process

There are fewer moving parts in single-hung windows, which usually means that the installation process is easier and more affordable. Double-hung windows are typically more challenging to install. However, professionals who have experience with both window types should be able to install them without issue.

Cost Considerations

Single-hung windows are often less expensive than double-hung ones. Since there aren’t as many moving parts in a single-hung window, the construction process is more affordable. However, the material that’s used to make the window plays a role in pricing. For example, a double-hung window made of vinyl may be less expensive than a single-hung one made from wood.

Energy Efficiency

Both windows can be highly efficient when properly installed. The material that the frame is constructed with determines how efficient the entire window is. For example, fiberglass and vinyl windows are made with multi-chambered frames, which means that heat moves through them at a slower rate. If you install these windows, they can be more effective at keeping your home cool during the summer and warm once the winter arrives.

Some single-hung and double-hung windows come with insulating foam, which offers more efficiency. Because single-hung windows only have a small number of moving parts, air infiltration is less likely, which is why they can be more efficient than their double-hung counterparts.

When to Choose a Single-Hung Window

Single-hung windows are easy to use and have a more traditional appearance. They offer an ample amount of energy efficiency, which means that you should benefit from lower monthly utility bills. Since these windows are easier to make, they are usually less expensive. Single-hung windows are often 10-25% cheaper than double-hung ones. If you plan to install the window high on a wall where you can’t reach the upper sash, a single-hung one might be preferable.

When to Choose a Double-Hung Window

Double-hung windows offer better air flow and simpler maintenance. Since you can open both sashes at the same time, you have more control over how much air enters your home. In rooms with just one window, the double-hung variety may be superior since you can keep both sashes open for improved air circulation. Maintenance is also easier with these windows since both sashes can be tilted. You don’t need to go outside to clean the window’s exterior.
