What is a Double-Hung Window?

Versatile and functional, double-hung windows are characteristic of traditional architecture. Historically, we most often find these types of windows on Colonial, Cape Cod, Victorian and cottage style homes, but double hung windows continue to be very popular today. The signature characteristic of the double-hung window is that both the top sash and bottom sash are operable, allowing for more adjustable ventilation and easier cleaning. In contrast, a single-hung window can only be opened using the lower sash.

Double-hung windows are a hallmark of high-end homes because their ease of use, safety, and easy maintenance increases a home’s value.

In this article, we'll explain why double-hung windows are an attractive option, cover the practical considerations, and look at how to choose the right window for your remodel or new construction.

Double-Hung Window: Definition and Features

A double-hung window has superior functionality because of its two operable sashes; it can be opened either by sliding the upper sash down, the lower sash up, or moving both sashes to the middle to maximize fresh air circulation. Modern double hung windows also have tilt pins that allow them to tilt inwards for easy cleaning.

What is the difference between a double-hung window and a single-hung window?

Unless you’re a window expert, it’s hard to tell the difference between double-hung and single-hung windows when you see them in a closed position. The difference is easily visible when a double-hung window is open, because all double-hung windows have two operable sashes. With a single-hung window, the top part of the window stays closed and only the bottom sash opens. Double-hung windows have more moving parts that allow both the top and bottom sash to open and be positioned in several ways.

What are the advantages of double-hung windows?

Double-hung windows offer superior ventilation to other window styles because with both sashes open, warm air flows out the top while cool air flows in the bottom. These energy efficient windows are Energy star rated, which means a lower monthly heating and cooling bill. Marvin’s line of double-hung windows is ranked Energy Star Most Efficient 2022.

Many people prefer double-hung windows because cleaning is much easier when both sashes can tilt inward. Cleaning a stationary sash requires you to reach the window from the exterior, which makes it difficult to tackle home window cleaning safely. Double-hung windows are a safer option because homeowners can simply pull down and tilt each sash to easily reach all of the exterior glass from inside the home — no ladders needed!

Double hung windows are ideal for replacement projects; they’re available in designs that suit a wide variety of home styles. Window sashes might have a single pane of glass, multiple panes (known as divided lites on modern windows) or a combination of both.

What are the disadvantages of double-hung windows?

The added features and convenience provided by double-hung windows makes them more expensive. As a result, upgrading to double-hung windows typically costs more than choosing a similar single-hung style. However, the high return on investment provided by double-hung windows means that higher upfront costs are usually offset by the home’s increased resale value.

The casings on double-hung windows are deeper than those of single-hung windows. This is because each sash requires its own track in order to move independently. However, the casings still fit neatly into standard wall framing, and the sashes are a similar size to those of single-hung windows so they won’t appear any bulkier.

The double-track configuration of double-hung windows can slightly reduce a window's airtight qualities. This is unavoidable because having two tracks instead of one creates an additional separation where the two sashes meet, allowing more air infiltration than other window designs. However, modern, high-quality window manufacturers like Marvin have engineered their products for a superior seal, eliminating any noticeable differences between installed double-hung and single-hung windows.

Types of Double-Hung Windows

Double-hung windows are available in an impressive variety of styles and configurations. An extensive selection of wood and fiberglass framing options make it easy to combine care-free maintenance with custom finishes that match your home. Double hung windows can be used alone, or in combination with other styles to expand the view and let in more light.

Double Hung & Transom Windows

Transom windows are installed above a window or door to let in additional light; they might be stationary, or operable to increase ventilation as well. Pairing a double-hung window with a transom is a great way to increase the glass area while maintaining a traditional look. Adding a transom at the same time you replace a double-hung window helps to save on installation costs.

Round-Top Double-Hung Windows

Half-round windows can also be combined with a traditional double hung window to create a round top or Palladian style window. Quarter-round and elliptical styles are also available to create custom designs that preserve the architectural integrity of a home. However, only a limited number of window products are compatible with a round-top configuration.

Double Hung & Picture Window

Double-hung windows can be combined with picture windows to create a variety of sizes and configurations. Generally, the center window in a three-panel picture window is a fixed-glass pane that does not open. This center window has no dividers to provide a clear picture of the view. Only the two side windows in a picture window configuration would be double-hung windows. A double-hung and picture window combination might also be configured as a bay window.

Frame-in-Frame Double Hung Inserts

A frame-in-frame window is sometimes referred to as a double hung insert. A double-hung insert is an option when a homeowner wants replacement windows and their existing wood or aluminum window frames are structurally sound. Using a frame-in-frame replacement window makes it possible to preserve interior and exterior frame material, an advantage when restoring older homes.

Where To Use Double-Hung Windows

The best place to use double-hung windows is … anywhere in the home! That's because no other window option gives you the versatility and value of double-hung windows. They can be used anywhere you'd consider using a traditional single-hung window, a casement window, or a fixed pane.

Double-hung windows are often the best option for a home's upper level. It can be impossible to safely clean the exterior of your window glass in a two or three story home, and hiring a professional can be expensive. The tilt feature on Marvin’s double hung windows makes it easy and safe to clean them yourself. Double-hung windows are also a safer choice for small children’s rooms, because you can open the top sash just a few inches for ventilation and leave the lower sash closed for safety.

Shopping for new windows? Double-hung replacement windows give your home improved ventilation and a superior seal against winter weather. You can choose custom exterior and interior finishes, and add grids or transoms for a more traditional look. Replacement windows should match your home’s architecture; but not at the expense of energy efficiency. Marvin offers solid wood windows for new construction and historic homes.
