In a home, windows do more than just let in light. They affect ventilation, security, and overall comfort. Choosing the right type can also add value to your home. Two common options are casement and double-hung windows. But the question many homeowners have is: which option is better, casement windows vs. double hung?
In this blog post, we’ll compare double-hung vs. casement windows to help you decide which is the best fit for your needs.
What Is A Casement Window?
A casement window is hinged on the side and swings open like a door, either outward or inward. It has a simple, functional design with a single sash holding the glass pane. Operated by a crank or lever, it opens fully for maximum ventilation and clear views. When closed, it forms a tight seal, reducing drafts and improving energy efficiency.
These windows come in different styles, such as single-frame, double-frame, and push-out designs, and can be made from wood, vinyl, or metal. Casement windows are popular for their stylish look, ease of use, and ability to complement both modern and traditional homes.
| PROS | CONS |
| Great Ventilation; Opens fully to let in maximum airflow, perfect for catching breezes. | Limited Size: Hinges restrict how large the window can be. |
| Energy Efficient: Tight seals prevent drafts, reducing energy costs. Many models include energy-saving glass. | Higher Cost: More expensive due to custom sizing and energy-efficient features. |
| Better Security: Built-in locks in the frame make them harder to break into. | More Maintenance: Hinges and cranks need regular cleaning and lubrication. |
| Easy to Clean: Opens wide, making both sides of the glass easy to clean. |
What Is A Double-Hung Window?
A double-hung window features two movable sashes, one at the top and one at the bottom, that operate independently for better airflow. Hot air can escape through the top while cool air enters from below, improving ventilation. Many modern designs include tilt-in sashes, making cleaning easy, even on upper floors.
Typically rectangular, these windows come in different styles, materials, and glazing options to suit different home designs. With their ease of use, energy efficiency, and classic appeal, they are a popular choice, especially for traditional homes like colonial and Victorian styles.
| PROS | CONS |
| Simple Maintenance: Tilt-in sashes allow easy cleaning of both sides without going outside. | Less Energy Efficient: Moving parts and dual sashes can lead to minor air leaks unless upgraded with energy-efficient features. |
| Safety Features: Keeping the top sash open while the bottom stays closed adds safety for homes with kids or pets. | Complex Repairs: More moving parts mean repairs can be trickier than with simpler window designs. |
| Space Saving: Since they slide vertically instead of opening outward, they work well in small or high-traffic areas. | Potential Drafts: Seals can wear over time, leading to air leaks and higher energy costs. |
| Better Ventilation: Both sashes open, allowing fresh air in from the bottom while warm air exits through the top, improving airflow. |

What Are The Key Differences Between Casement Windows and Double Hung?
Now that you know what casement and double-hung windows are, let’s get into the main differences between them.
#1. Opening Mechanism
Casement windows swing outward or inward on hinges, much like a door. This allows for full ventilation and clear outdoor views. A crank handle makes them easy to open, even in hard-to-reach spots, which is helpful for those with limited mobility. Meanwhile, double-hung windows slide up and down with two movable sashes. Homeowners can open the top or bottom sash or both, making it a flexible option for airflow. Keeping the lower sash closed adds extra safety for children and pets. While casement windows provide maximum airflow, double hung allow controlled ventilation with added security.
#2. Energy Efficiency
Sealing tightly when closed, casement windows minimize air leaks and improve insulation, making them highly energy-efficient. Their design also helps capture breezes for natural ventilation. Double-hung windows can also be efficient, but their sliding design may not seal as tightly unless they have quality weather stripping. Adding double or triple glazing to either type can improve insulation and lower energy costs.
#3. Cost
Pricing varies between the two options, with casement windows generally costing more due to their hinge and crank mechanism. While they require a higher upfront investment, their energy efficiency can lead to long-term savings. In contrast, double-hung windows are more affordable and widely available, making them a budget-friendly option without sacrificing style or durability. The cost of both casement windows and double hung depends on material, installation, and energy efficiency upgrades.
#4. Style and Aesthetics
Appearance plays a big role in window choice. Casement windows have a sleek, modern look with minimal framing, offering wide, unobstructed views that are perfect for contemporary homes. On the other hand, double-hung windows have a more traditional style, fitting well with historic or classic home designs. Their symmetrical appearance and optional divided panes add charm and character.
#5. Durability and Maintenance
Longevity depends on maintenance. Casement windows need regular checks on their hinges and cranks to keep them operating smoothly. Since they open outward, they are more exposed to the elements and may wear faster if not maintained. Double-hung windows, however, have fewer mechanical parts but may develop sash balance issues over time. However, cleaning them is easier since both sashes tilt inward, allowing for convenient access from inside.
#6. Security Features
Protection differs between these two options. Casement windows offer strong security due to their built-in crank locks, making them difficult to force open. Their tight seal also reduces potential entry points for intruders. Comparatively, double-hung windows provide a reasonable level of security but may be more susceptible to tampering if not locked.
#7. Ventilation
Casement windows open fully, allowing fresh air to flow freely into a space. This makes them beneficial in areas that require more ventilation, such as kitchens and living rooms. Double-hung windows offer controlled ventilation since either sash can be adjusted independently, though they do not provide as much airflow as casement designs.
#8. Screen Placement
When choosing between double-hung windows vs. casement, screen placement may impact maintenance needs. Casement windows have screens on the inside, which may require more frequent cleaning but are simple to remove when needed. Double-hung windows feature external screens, protecting the panes from dirt and debris while making them easy to clean.
#9. Installation Process
Fitting these windows also requires different approaches. Casement windows need precise measurements and careful installation due to their hinge system, which often results in higher labor costs. In contrast, double-hung windows have a simpler design, making them easier and more affordable to install, especially for DIY projects.
#10. Noise Reduction
Blocking outside noise is another consideration. Casement windows provide excellent sound insulation due to their tight seal, reducing noise intrusion effectively. Double-hung windows can also minimize sound, but their sliding mechanism may allow some noise to pass through if not properly sealed. Comparing casement vs. double-hung windows, homeowners in noisy areas may prefer the superior seal of casement windows.
Casement Window vs. Double Hung: Which One Should You Choose?
After understanding the pros and cons of casement windows vs. double hung and their basic differences and definitions, your final decision between the two depends on your needs. Here are some points to keep in mind:
Choose Casement Windows If:
- You want windows that open fully for maximum airflow.
- Energy efficiency matters, and you need a tight seal to prevent drafts.
- You live in a windy area and need strong locks and seals for extra security.
- You want a modern design with a clear, unobstructed view.
Choose Double-Hung Windows If:
- You prefer the classic look of double-hung windows, which fit most home styles.
- Easy maintenance is important and you want tilt-in sashes for simple cleaning.
- Safety is a concern and you need a child-friendly option where only the top sash opens.
- You have limited exterior space (since double-hung windows don’t swing outward).
