How Do Double-hung and Casement Windows Open and Are They Easy to Use?

Looking to purchase a replacement window for your home? There are several different types of replacement windows, and the wide variety of options can be confusing. What style of window do I currently have? What type of window do I want to replace my window with? The choices can make you dizzy! In this post, we will explain the differences between a double-hung window and a casement window and share some helpful tips to make your decision a little easier.

Stanek double-hung windows are easy to open due to their spring-loaded balance system that aids in lifting the window. This custom-tuned constant force system along with fully integrated sash lift rails ensure smooth operation for the life of the window. This window style also has an operable upper and lower sashes which tilt in to allow for easy cleaning from the inside.

Stanek casement windows have a fold-down handle that easily opens and closes the window, making them easy to use. Because the handles fold down, they are compact and won’t obstruct your window treatments. To open a casement window, you must open the lever lock and then rotate the easy-turn handle. All casement windows open to a 90-degree angle, which allows the inside and the outside of the window to be cleaned safely from the interior of your home.


When comparing both window styles, a significant difference between the two is that double-hung windows have screens on the outside of the window, while casement windows have the screen on the inside. However, Stanek casement window screens are color matched with the interior of the window – including woodgrain options, so the screens look as though they are part of the window.

What’s the View, Best Location, and Cost for Double-hung and Casement Windows?

Outdoor View: An essential element of your choice in replacement window style is the outdoor view. Double-hung windows have a meeting rail (the horizontal bar) in the center of the window that can potentially be at eye level. This could prohibit your view of the outdoors depending on the location of the window. If you’re looking for an unobstructed view, casement windows may be the right decision for you. Casement windows do not have bars in the middle of the window, providing a clear view of the outdoors.

Screens can often blur or obstruct your view. Whether you choose a double-hung or casement window, both offer you a beautiful view of nature that is so clear you feel as though you are a part of it. Our screens are strong and durable for excellent airflow, visibility and longevity.

Replacement Window Cost: The price of replacement windows can vary, but on average, double-hung and casement replacement windows are similar in cost. Window material, glass type, how many panes of glass, and other options have more impact on the cost of any window. Quality windows that are built to last will cost more than cheap alternatives but are worth the investment. A high-grade window that is correctly installed will last longer, lower energy costs, and protect your home from damage.

Best Location for your Replacement Windows: Something to think about before you decide which type of window is right for you is where the window will be placed Consider what type of room your windows will be in, how the room is used, and what obstructions may be present.

For example, double-hung windows placed over your kitchen sink would be tough to open and close, whereas a casement window would be an ideal choice. Casement windows are also ideal for openings where you’d like to have an unobstructed view of the outdoors, while double-hung windows are great for bedrooms because of their ability to have both the lower and upper sash opened, which allows maximum ventilation.

And, don’t forget to look at your windows from the outside of your home. It is important to consider the proximity to exterior pathways or seating areas. Since casement windows open outward, they can be an obstruction or hazard, making double-hung windows an ideal option near walkways, decks, and patios.

What Architectural Style is Most Suitable for Double-hung and Casement Windows?

Both window styles suitable for any type of home. Double-hung windows are popular with more traditional home styles, such as colonials, though a casement can modernize and update the look. Casement windows have clean, simple lines that complement any architectural style, from traditional to modern.

 

Ventilation and Energy Efficiency of Double-hung and Casement Windows

Energy Efficiency: The top and bottom sashes of double-hung windows fit very snugly in the window frame, which limits air infiltration. This, coupled with triple weather seals makes Stanek double-hung windows exceptionally energy efficient and gives them excellent air infiltration ratings. Casement windows, on the other hand, tend to have a slightly tighter seal than double-hung windows when they are locked, because the lock pulls the window sash tightly against the frame and weather seals. The tighter the seal of the window, the more energy efficient it is. Both styles utilize high density foam for superior insulation in the multi-chambered frames.

Ventilation: Double-hung windows have the advantage of both a top and bottom sash that can slide up and down, allowing for a nice breeze to enter the room. Casement windows also allow plenty of air inside because, when the window is open, the window surface area acts as a sail, catching the wind and sending it into your home. Therefore, both options provide excellent ventilation.

Glass Options: Triple-pane glass is standard in both Stanek window styles. These insulated glass units utilize warm-edge spacers to provide a superior seal and prevent the transfer of heat. Argon gas between the window panes further insulates the glass.
