What Are Double Hung Windows?

4/22/2016 12:27:44 PM

Whether you’re replacing your home’s existing windows or choosing a style to install in your new home, double hung windows are certainly worth considering. As a long-established style, double hung windows are some of the most widely recognized windows available today.

Features of Double Hung Windows

In double hung windows, both the upper and lower sashes can slide up and down past one another. This is different from single hung windows that have only one moveable sash. This dual, independent movement is made possible by two grooves in the side jambs.

Some double hung windows have a full screen while others have only a half screen that you must position according to how you open the window. Each sash may be a solid pane of glass, or for added style, they may be divided by
decorative muntins set between the panes of glass. Glazing is also available to improve energy efficiency and provide UV protection for your furnishings.

Benefits of Double Hung Windows

This window style is certainly traditional, with a history dating back to the time when smaller sheets of glass were fitted between functional muntins to make a larger window opening. After all this time, double hung windows have remained a popular option. Here’s why:
  • Versatility: Double hung windows come in many different shapes, sizes, materials and colors to match a variety of home styles and personal preferences. They can also be arranged in different ways. You might install a single window, place two or three in a row, or use this style in bay and bow window configurations.
  • Easy to clean: For convenience, some modern double hung windows come with tilt-in sashes to make cleaning a breeze. This prevents you from having to hire a professional window washer, even for upper story windows.
  • Great for kids’ rooms: If you want to enjoy natural ventilation in your child’s bedroom, double hung windows are the safest choice. You can open the upper sash and allow a nice breeze to enter while keeping the lower sash locked. This prevents the possibility of the child climbing or falling out of the window.
  • Air conditioner friendly: Do you supplement central air conditioning with window units? Double hung windows are the easiest style to install room A/Cs in, since you don’t need extra pieces of Plexiglas to close off larger openings found in sliding and casement windows.

Other Considerations

Even if you’re totally sold on double hung windows, don’t make your purchase without knowing the following:
  • Lower energy efficiency: While double hung windows are available with quadruple weatherstripping, the openings aren’t as airtight without this feature. Fortunately, modern double hung windows are built more efficiently than older models.
  • Limited ventilation: Whatever the dimensions of your double hung window, the sliding sashes allow you to only open half of it at once. This restricts ventilation to a small degree.
