Casement vs. Double-Hung Windows Explained
Before you can compare the pros and cons of these windows, brush up on what they look like.
Casement windows use cranks to open and close, so you can open them with one hand. They push open, extending beyond the envelope of your house. Casements are often used anywhere you need to reach to open a window. For example, casements work well above a kitchen sink since it's easier to turn a crank than lean over the sink basin and push a double-hung window.
Double-hung windows move up and down in a frame. Some allow you to move both the top and bottom sashes, while others only let you move the bottom. Double-hung windows are all-purpose windows.
Benefits of Casement Windows
One of the main benefits of casement windows is that they look different! Many people find that a casement window adds a clean modern style, especially since they don’t have the sash dividing the window like a double-hung window does. If your home is contemporary, they may be a good choice.
In terms of insulation efficiency, casement windows create the tightest seal. When the casement window is closed, all four sides of its sash press firmly into the frame, stopping air leaks.
That tight seal helps control your home’s temperature by keeping heating and air conditioning in. If your existing windows let air into your home, you'll likely see a decrease in utility costs by switching to casement windows.
Another convenience factor of casement windows is that they are among the easiest windows to open and close - a great benefit for older homeowners who might have trouble opening stuck windows.
Benefits of Double-Hung Windows
Double-hung windows are flexible enough to work well in most rooms and home styles, and are a must for historic houses. They also accommodate window air conditioning units. Casement windows cannot accommodate window air conditioners, so staying cool is trickier if you choose casements.
Double-hung windows usually last longer with less maintenance required. If the crank on a casement window fails, you'll need to repair it before you can open the window. Since double-hung windows have fewer moving parts, there's less chance of mechanical failure.
Comparing Casement vs. Double-Hung Windows
Main benefits aside, here's how the two window styles stack up:
- Aesthetic - It's a draw. Individual homeowners may be drawn to one style over another, or decide to mix and match.
- Cleaning - It's a draw. Casement windows are fairly easy to clean. Simply crank open the window, then wash both sides from your home exterior. Modern double-hung windows are fairly easy to clean as well, since they tilt in for simple cleaning. If you have old double-hung windows, getting a deep clean is difficult.
- Durability - Casement windows get exposed to the rain and wind when they are open, so they can weather faster than double-hung windows. The frame reduces double-hung windows' exposure to weather. For this reason, double-hung windows are generally more durable.
- Tight seal - Casement windows have an airtight seal when they're closed. Older double-hung windows can allow air in through the top, but it shouldn’t be an issue when installing brand new windows. Consider this one a wash.
As you can see, the question isn't "are casement windows better than double-hung" but which type of window fits your style and works with your home. To learn more about replacement windows, or to get a quote, contact us.
