What’s the Difference Between Casement Windows and Double Hungs?

Casement windows and double hung windows have a few differences.


The biggest difference is how they open and close. Casement windows operate with a crank handle to swing out. Double hung windows slide up and down to open and close.

Screen Placement

Casement windows have screens on the interior side of a window, so they are more protected from weather and dirt. Double hung windows have screens on the exterior side of a window, so you may notice they accumulate a bit more dirt.

Viewing Area

Another difference between casement and double hung windows is the viewing area. Casement windows offer uninterrupted views. Double hung windows have a check rail in the middle to divide the window into two sash.

What’s More Energy Efficient: Casement or Double Hung Windows?

Things to Consider When Choosing Casement vs. Double Hung Windows

  • Natural Light: Both casement and double hung windows can provide natural light. A casement window doesn’t have a check rail like a double hung so it can offer clear views.

  • Size: Casement windows can have size limitations because the hardware needs to support the weight of the window sash. Double hung windows don’t face that problem, but they can also have size limitations in height.

  • Air Ventilation: Casement and double hung windows are some of the best windows to improve air circulation. Casement windows can open wide for ventilation and can capture cross breezes. Double hung windows can cycle warm air out through an opened upper sash and usher in cool air through an opened lower sash.

  • Placement: Casement windows work well above kitchen sinks because it can be harder to reach to open a double hung.

  • Home Style: Double hung windows fit traditional styled homes, especially when they have window grids. Double hung windows often appear in contemporary styled homes, too. Casement windows can also have grids to fit traditional homes. They also appear in contemporary styled homes.

  • Maintenance: Marvin Replacement Ultrex fiberglass windows require virtually no maintenance.
