What Is a Double-Hung Window?

Windows are one of the most important aspects of any home. They allow you to experience the wonders and beauty of the outdoors – all from the comfort of your residence. They also provide the necessary ventilation. Updated exterior windows can also help homeowners enhance the look and comfort of their property, adding just as much curb appeal and value as modern siding and scenic landscaping.

When seeking window replacements for a home improvement project, a variety of options are available. Given their features and many benefits, double-hung windows remain one of the most popular types. Here, New Jersey Siding & Windows, Inc. discusses what double-hung windows are and why they are a great option for any house.

Identifying Double-Hung Windows

A double-hung window is a classic style that balances design and functionality well. Its name refers to its ability to open from the top and the bottom. This is different from single-hung windows, which can only open from the bottom. This traditional rectangular window does this by utilizing two sashes: one upper and one lower. Double-hung windows can feature a single glass pane in each sash or the glass may be divided into many panes, separated by dividers known as muntins (more commonly referred to as grids).

These windows are also designed for greater convenience. Generally, the casing on a double-hung window is thicker than a single-hung window. This is largely because both sashes must exist on their own track. This allows each sash to move up and down independently.

The Advantages of Double-Hung Windows

The reason double-hung windows are a popular choice for homeowners is because of the benefits they offer. When choosing to replace your current windows with this style, you can expect the following:

Easy To Clean

Thoroughly cleaning your home’s windows requires you to wash both the interior and exterior. This can be incredibly difficult for second-story windows that feature a top sash that doesn’t open. Since double-hung windows have top and bottom sashes that move, users can wipe down both the interior and exterior sides of the window with ease.

Enhanced Ventilation

Windows are intended to add great functionality to a home. One of their abilities is to provide ventilation – and there’s nothing quite like having fresh air breeze through the house. A home with poor ventilation could be subject to unpleasant odors and possible mold growth. Because they can open at the top and bottom, double-hung windows offer homes superior ventilation options. You can even leave each sash half open, so the bottom opening lets fresh air blow in and the top opening releases warm air back outside.

Improved Safety

When it comes to small children, open windows can be a safety hazard. The thought of a small child falling through the opening of the window is always a concern for a parent or guardian. However, double-hung windows give the adults at home greater peace of mind because they can open the top sash while keeping the bottom closed to help keep active little ones safely inside.


Operating a double-hung window is simple, making it easy for users to let in the fresh air, let out unwanted odors, and control the temperature in the house. Opening and closing these windows requires only applying downward or upward pressure, depending on which sash you plan to open or close.

Greater Home Value

Are you selling your home in the near future? Because of their excellent functionality, double-hung windows are a highly desirable window type. Replacing your current windows with this style may offer a greater return on investment in terms of home value.
