What’s the difference between double hung and casement windows?
Casement windows and double-hung windows have a few differences. Learn more about the differences and why you might favor one window style over another.
Operation
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 sashes.
What is a casement window?
A casement window is also known as a crank window because it opens and closes by turning a crank handle. Casement windows swing outward. They usually have a vertical rectangle shape. The difference between casement vs. awning windows is the window’s orientation. Awning windows have a horizontal orientation.

What is a double hung window?
A double-hung window has two sashes that move up and down. The difference between a double-hung vs. a single-hung window is the top sash of a double hung window can move up and down. The top sash of a single-hung window does not move.

What’s more energy efficient: Casement or double hung windows?
Infinity Casement and Double-Hung Windows both have energy efficient features. Casement windows can provide a tighter seal to prevent air leakage because of their latch lock. Older double-hung windows can suffer air leakage if they don’t close tightly.
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 as kitchen windows 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: Infinity Ultrex fiberglass windows require virtually no maintenance.
