When choosing replacement windows, the glass package and frame material matter—but so does the way the window actually operates.
Two of the most common options for Chicagoland homes are double-hung windows and casement windows.
Both can provide ventilation, natural light, and improved performance, but they create very different looks and function differently from day to day.
What Is a Double-Hung Window?
Double-hung windows have two movable sashes that slide vertically within the frame.
Depending on the design, you can open the bottom sash, lower the top sash, or use both to increase airflow.
They are especially common on:
- Traditional homes
- Colonial-style homes
- Cape Cod homes
- Older Chicago-area properties
- Homes with multiple windows arranged side by side
Their familiar proportions make them one of the most versatile replacement window styles.
What Is a Casement Window?
Casement windows are hinged along one side and open outward using a crank or handle.
Rather than sliding within the frame, the entire sash swings outward.
Casement windows can work particularly well when homeowners want:
- Larger uninterrupted views
- A cleaner, more contemporary appearance
- Strong ventilation
- Easy operation in certain locations
- Fewer horizontal lines across the glass
They are frequently used in kitchens, living rooms, and newer or transitional home designs.
Which Style Provides More Ventilation?
Both windows provide ventilation, but they handle airflow differently.
Double-hung windows allow air to enter through the lower opening while warmer indoor air can escape through the upper opening when both sashes are open.
Casement windows can open almost the entire window area.
Because the sash projects outward, it can also catch passing breezes and direct them into the room depending on the wind direction.
For spaces where ventilation is a major priority, casement windows can be especially useful.
Casement Windows Can Provide a Cleaner View
Because double-hung windows contain two separate sashes, there is typically a horizontal meeting rail across the middle of the glass.
Casement windows generally provide a larger uninterrupted glass area.
That can make them attractive for rooms overlooking:
- Backyards
- Gardens
- Landscaped areas
- Patios
- Scenic views
If maximizing visible glass is important, also consider how window frame thickness affects the finished appearance.
Double-Hung Windows Offer a Classic Appearance
For many homeowners, the biggest advantage of double-hung windows is architectural compatibility.
Their proportions work naturally with a wide range of traditional homes.
They also pair well with decorative grille patterns.
Homeowners who want to maintain the character of an older property may prefer double-hung windows because they can provide modern performance without dramatically changing the exterior appearance.

Think About Where the Window Is Located
The location of the window can help determine which operating style makes more sense.
Above Kitchen Counters
A casement window may be easier to operate because the crank can be reached without having to lift a sash.
Bedrooms
Double-hung and casement windows can both work well, provided the window meets any applicable egress requirements.
Living Rooms
Either style can work, depending on whether you prioritize a traditional appearance or larger uninterrupted views.
Walkways and Patios
Remember that casement windows open outward.
If the window faces a narrow walkway, deck, or high-traffic area, the projecting sash needs to be considered.
Which Is Easier to Clean?
Many modern double-hung windows include tilt-in sashes, allowing homeowners to clean the exterior glass from inside the home.
Casement windows can also be relatively easy to maintain, although access may vary depending on the size and location of the window.
When comparing products, ask how each window is designed to be cleaned and maintained.
What About Energy Efficiency?
Window style is only one part of energy performance.
Factors such as glass packages, weatherstripping, frame construction, installation quality, and air leakage all matter.
Casement windows can create a tight seal when the sash is pulled against the frame and locked.
Modern double-hung windows can also provide strong performance when they are properly designed and installed.
Before comparing windows by style alone, review the actual performance ratings. Our guide to window energy ratings explains what those numbers mean.
Which Window Style Looks Better?
There is no universal answer.
Choose double-hung windows if you prefer:
- Traditional proportions
- Classic architecture
- Familiar operation
- Decorative grille options
- Vertical window openings
Choose casement windows if you prefer:
- Cleaner sightlines
- Larger uninterrupted glass
- Strong ventilation
- Contemporary styling
- Crank operation
Many homes use more than one window style depending on the room.
The goal is to create a consistent exterior while selecting windows that also function well from the inside.
