Single Hung vs Double Hung Windows

Double vs Single Hung

The window is one of the essential features of a home. It allows light and air to enter and provides a view of the outside world. When choosing windows for your home, you have many options. Single-hung and double-hung windows are two of the most popular types of windows. However, both have pros and cons, which you’ll need to consider before deciding. This blog post will compare the pros and cons of single-hung and double-hung windows to help you make the best decision for your home.

What are single-hung windows?

In single-hung windows, only the lower sash moves vertically. The upper sash remains fixed at all times during opening. When the window is open, the lower sash partially obscures the upper sash. A single-hung window looks like a double-hung window, except that a double-hung window has both an upper and a lower sash that can be opened.

What are double-hung windows?

Double-hung windows are a type of window with two hinged sashes. The lower sash is called the “lower sash”, and the upper sash is called the “upper sash”. Double-hung windows usually have two panes of glass in each frame, although there may be more than two panes if the window includes an interior shutter. Double-hung windows can feature a single or double-pane configuration, but most have two panes of glass.

What are the main difference between the two?

Single-hung windows are the most common type of window. It’s also the simplest to install and maintain. A single hung window has two sashes joined by a single hinge, which means you can open and close it with one simple motion. It’s a highly efficient design that requires less force to operate than double-hung windows, especially in colder climates where you might need an extra push on your window to get it open or closed.

Double-hung windows are also popular for homes with Low-E or insulated glass to save energy costs. They’re more expensive than single-hung windows, but they offer better insulation and security features that make them worth the price.

Pros of single-hung windows



Single-hung windows are more secure than double-hung windows because they have one lock and are only open in one direction. As a result, their locking system is less likely to fail, and it is easier to remember to lock the window with only one lock.

Energy Efficient

As time passes, single-hung windows become increasingly more energy efficient due to decreased air infiltration. Unlike other windows, they only move in one direction, which may have more movement and allow for more significant air infiltration. A single-hung window will also increase efficiency because of its energy-efficient glass, frame, and insulation. The better insulated your windows are, the less you’ll spend on heating and cooling costs throughout the year. They also have less chance of entering moisture into your home and creating mould, mildew, and other problems.

Save Space

A single hung window takes up no interior space and does not open outward, so it is perfect for adding a lot of light and ventilation to a room without sacrificing square footage. In addition, it will give your space the illusion of being larger in smaller spaces, like bathrooms or guest rooms or areas with high traffic.

Not Expensive

Single-hung windows are less expensive than double-hung windows and can be cheaper than triple-hung windows. They don’t require as much work to install and use fewer materials. Additionally, they don’t require special techniques or tools to install them on the frame. You will only need a drill and hammer to install these windows.


Single-hung windows move only in one direction, but you can choose from many shapes, trims, and finishes to match your style. In addition, single-hung windows come in a variety of forms, including eyebrows (curved edges), arches (rounded at the top in a half-circle), Gothic windows (sharply arched windows instead of rounded ones), as well as several unique geometric shapes, all of which can be customized to fit your home’s needs!

Cons of single hung windows

Single-hung windows have less ventilation than double-hung windows because they are mounted without a sash weight. It means there is no way to open them fully, and you can only open them halfway. In addition, the bottom section of single-hung windows will not open entirely because they are mounted to the bottom of the frame instead of the top.

Difficult to clean:

Single-hung windows are relatively easy to clean, but you must go outside or stick your head out of the window to clean the top half. The bottom sash can be easily cleaned, but the top half is more complicated. To open the window, you must first lift the bottom sash.

Repair challenges:

Single-hung windows are more challenging to repair than double-hung windows since a professional window technician must replace the upper sash.

Pros of double-hung windows

Easy to clean:

It is easy to clean your windows when both sashes move, as you can clean the interior and exterior more easily. A two-story house may make this especially beneficial if you cannot reach the outside window.

More designs available:

A wide range of architectural styles can be accommodated by double-hung windows, available in customized frames, glass finishes, and sizes. You’ll enjoy the custom design options available if you own a Craftsman, Colonial, or Cape Cod house.

Keeping children safer:

You can open the top sash of a double-hung window and keep the bottom sash closed to prevent a child from climbing out. It makes them safer for children because small children can fit through a window opening. In addition, you can increase their security when you properly maintain and lock your double-hung windows.

More ventilation:

You can solve the humid air problem in your home with double-hung windows that use both sashes to draw more air into your kitchen, bathroom, or laundry room. Leaving each sash half-opened allows warm air to escape, allowing fresh air in.

Cons of double-hung windows

Expensive cost:

Double-hung windows are also more expensive than single-hung ones, so they will cost more to install and maintain over time. They also require more maintenance due to their larger frames and casings.

Lack of energy efficiency:

Double-hung windows let in a lot more heat and cold air than single ones, which can increase your heating and cooling costs in the winter and summer. It may be an issue for you if you live in a climate that gets extremely hot or cold during certain times of the year.

Difficult to maintain:

Double-hung window styles will require more maintenance than standard single-hung window styles because of their larger surface area and a more significant number of parts on each frame member.


After reading this article, you should understand the pros and cons of single vs. double-hung windows. Single-hung windows are more affordable and easier to install, but they are not as used to clean as double-hung windows. On the other hand, double-hung windows are more expensive and require more maintenance, but they provide better insulation and ventilation. Ultimately, the type of window you choose should be based on your budget, needs, and preferences.
