Single-Hung vs. Double-Hung Windows

Whether you’re choosing windows for a new home or replacing damaged ones, the windows you buy can make a huge difference in terms of the energy efficiency, aesthetic, and value of your home. One of the choices you will need to make is if you want a single-hung or a double-hung window. Continue reading to find out key differences between single-hung vs. double-hung windows and what they have to offer in terms of features like ventilation, security, ease of installation, and maintenance. 

What is a Single-Hung Window?

Single-hung windows, which are also known as single sash windows, are windows that have an upper and lower sash, with the bottom being moveable and the top being stationary. Sashes refer to the portion of the window that holds the glass in place. 

Since only one part of the window can be moved, these kinds of windows are easier to install, more cost-effective, and more weather resistant. As a result, single-hung windows are a popular choice for installation in new homes and for replacement of existing windows.

What is a Double-Hung Window?

Double-hung windows, also called double sash windows, have two fully moveable sashes, meaning both the upper and lower portions of the window can be opened and closed. 

These types of windows are easier to clean and they allow for greater ventilation, which has made them a popular choice among many homeowners. Although these windows are a good option for any type of house, stylistically, they are especially suited for Cape Cod, Victorian, Colonial, and Craftsman style homes.

Comparing Single-Hung Vs. Double-Hung Windows

When deciding on whether to choose single-hung vs. double-hung windows, it’s a good idea to understand the advantages and downsides of each type. 

First, let’s look at the pros and cons of single-hung windows:

Next, let’s look at the pros and cons of double-hung windows:

Now let’s break down each of those individual considerations so you can make the best possible choice for your home.

Energy Efficiency and Ventilation of Single- vs. Double-Hung Windows

When you consider the energy efficiency of single-hung vs. double-hung, single-hung windows are more energy efficient. One of the sashes is always kept in place, so they are less likely to get loose and allow air to leak out of the home. With double-hung windows, the seal of each frame can weaken over time. Eventually, this may lead to air leaks that make your home less energy efficient.

On the other hand, double-hung windows have better ventilation. Both the top and bottom sashes open, allowing for maximum airflow. If your home tends to be hot and stuffy, single-hung windows may not be the best choice.

Frame Materials For Single- vs. Double-Hung Windows

The frame materials for single- versus double-hung windows are actually the same. For both types of windows, you can choose between several options, such as aluminum, vinyl, fiberglass, and wood. Keep in mind that the material you choose will impact the overall cost of the project. Since double-hung windows are already more expensive, choosing a pricier frame material will add an additional expense to the project.

Is frame material more important to you than if a window is single-hung or double-hung? If so, you may choose to opt for a single-hung window in a high-quality frame instead of a double-hung window in a more cost-effective material.

Cleaning and Maintenance of Single-Hung vs. Double-Hung Windows

Both the cleaning and maintenance of double-hung windows is much easier because the top and bottom portions of the window open. This allows you to clean the inside and outside with ease. On the other hand, with single-hung windows, you need to go outside to clean the exterior portion of the window. 

For both types of windows, you can clean the glass by spraying it with a cleaner and wiping it down with a microfiber cloth.

Standard Sizes of Single-Hung vs. Double-Hung Windows

Both single-hung and double-hung windows can come in smaller sizes all the way down to two feet wide by three feet tall. However, double-hung windows are available in larger sizes. These windows can be as large as 6 feet wide by 12 feet tall.

If you have a lot of wall space you want to fill or are trying to maximize natural light, then you may want to opt for a double-hung window.

Security of Single and Double-Hung Windows

Single-hung and double-hung windows can both be secure. However, with double-hung windows, it takes a little bit more work. These windows need to be locked tight to ensure the safety of your home. Otherwise, the upper sash may begin to fall down to the point where the windows are unable to close all the way. 

Installation of Single and Double-Hung Windows

Both kinds of windows can be installed by a skilled DIYer, though it’s best to hire a professional. However, this is especially true with double-hung windows because there are more moving components. This makes the installation a bit more complicated. It provides many more opportunities to make mistakes that will need to be fixed by a window installer later.

Best Rooms for Single- and Double-Hung Windows

Generally, you want to choose double-hung windows in areas where you need the most ventilation. They tend to be a popular choice for areas where you want to prevent the buildup of moisture, like bathrooms and kitchens. Single-hung windows are a good idea for areas that don’t need the same amount of ventilation, like bedrooms.

Single-Hung Vs. Double-Hung Window Costs

Single-hung windows tend to cost less than double-hung windows. Windows that are single-hung can cost between $280 and $605, with the average being $445 per window. Double-hung windows generally cost between $310 and $665 per window.

Which Type of Window Is Best for My Home?

When you’re deciding on single- vs. double-hung windows, the best choice depends on your needs. Do you live in an area that’s cold? You may want to consider single-hung windows in order to better avoid drafts. If you’re concerned about energy efficiency, single-hung windows are also a good choice. However, if you’re in an area where the climate is warm, you may want to install double-hung windows. 

There are several variables that go into this choice, so really think about your needs before making a decision.
