When it’s time to replace your windows or choose new ones for your home, the variety of options can feel overwhelming. Two of the most popular window styles are casement windows and hung windows. While both provide ventilation, light, and curb appeal, they operate differently and suit different needs.
Below, we’ll break down the differences, their benefits and drawbacks, and help you decide which window style best fits your home.
What Are Casement Windows?
Casement windows are windows that are hinged on one side and open outward like a door, typically using a crank handle. They can open to the left or right, depending on your preference and room design.
Where they’re common: Casement windows are popular in modern and traditional homes alike and are often installed in kitchens, bathrooms, and hard-to-reach places where a crank makes them easier to open.
What Are Hung Windows?
Hung windows come in two types: single-hung and double-hung.
-
Single-hung windows: The bottom sash moves up and down, while the top sash stays fixed.
-
Double-hung windows: Both the top and bottom sashes can move up and down, and often tilt inward for easy cleaning.
Where they’re common: Hung windows are a staple in many classic home styles, including colonial and craftsman, and are frequently used in bedrooms, living rooms, and throughout multi-story houses.
| Feature | Casement Windows | Hung Windows |
|---|---|---|
| Opening Mechanism | Hinged at the side; opens outward with a crank | Sashes slide vertically up and down |
| Ventilation | Opens fully for maximum airflow | Offers moderate ventilation; only half the window can open at a time |
| Seal | Compression seal (closes tightly) | Sliding seal (more prone to slight air leakage) |
Pros and Cons of Casement Windows
Pros:
-
Superior Ventilation: They open fully outward, catching side breezes and directing airflow into the home.
-
Energy Efficiency: They close tightly with a compression seal, minimizing air leaks.
-
Unobstructed Views: No sash dividing the window vertically — just a clear pane.
-
Ease of Use: The crank handle makes them ideal for hard-to-reach places (e.g., over a kitchen sink).
Cons:
-
Vulnerable to Wind Damage: Strong winds can catch an open casement window and potentially damage hinges.
-
Obstructs Exterior Space: When open, they protrude outward, which may not be ideal for walkways, patios, or tight spaces.
-
Maintenance: The crank mechanism and hinges may require occasional upkeep or lubrication.
Pros and Cons of Hung Windows
Pros:
-
Classic Look: They have a timeless, traditional style that fits many architectural designs.
-
Space-Saving: They don’t protrude outward when open, making them ideal for patios or pathways.
-
Flexible Ventilation: With double-hung windows, you can open the top sash for ventilation while keeping the bottom closed (safer for kids and pets).
-
Easy Cleaning: Many double-hung models have tilt-in sashes for cleaning the exterior glass from inside your home.
Cons:
-
Air Leakage: The sliding seal is less airtight than a casement’s compression seal, so they can be less energy efficient.
-
Less Ventilation: Only half the window can open at once.
-
May Stick Over Time: Sliding sashes can become difficult to open if dirt accumulates in the tracks.
Utility: Where Each Excels
-
Energy Efficiency: Casement windows typically perform better because they seal tightly when closed.
-
Ease of Use: Casements are easier to open when installed in awkward places.
-
Safety: Double-hung windows offer safety flexibility since you can open the top sash only.
-
Maintenance: Hung windows are easier to maintain when upper floors are involved due to tilt-in sashes.
Which Should You Choose?
The right choice depends on your priorities and space:
-
Choose casement windows if:
You want maximum airflow, top-notch energy efficiency, and a modern, clear view with easy operation in hard-to-reach areas. -
Choose hung windows if:
You prefer a classic look, need to conserve exterior space, want easier cleaning for upper floors, and prefer a traditional window style.

Both casement and hung windows have unique advantages. Understanding how they function — and how they fit your home’s design and your lifestyle — will help you make a smart, lasting investment.
