Casement Windows vs. Double Hung Windows

Casement Windows vs. Double Hung Windows

Double hung windows are popular. Very popular. If you look around your home, these slider windows probably make up the majority of those windows. But did you know there’s a window with even more energy efficiency? Casement windows aren’t right for every window situation but they can be a fun and functional change for your space. In this article we’ll share the pros and cons for both window styles and some great placement options for you to consider.

What is a Double Hung Window?

A double hung window is one of the most popular replacement window styles chosen by homeowners. It is called a double hung window because both the top and bottom sashes are operable, move up and down. The ability to open both sashes creates increased airflow and ventilation, one of the big reasons this window is so popular. Both sashes of a double hung window can also tilt for easy cleaning. This is very helpful for windows on upper floors that would normally be very tough to clean on the outside. 

What is a Casement Window?

A casement window is attached to the frame by hinges on the left or right side of the frame. They come with a single window pane with one hinge on the left or right or with double window panes that swing open in the center. Casement windows are often held together by a casement stay and are opened by a crank, lever, or handle. Similar to a casement window, windows that hinge at the top are called awning windows and those hinged at the bottom are called hoppers. Casement windows are popular in spots where pushing a window open is tough, such as above the kitchen sink, and can be easily opened with one hand. They’re actually considered one of the easiest windows to open and close.

Pros and Cons Comparison

Casement Window Pros

Casement windows may not be as popular as the double hung window but it’s not far behind thanks to the many benefits of casement windows. 

 

  • Energy Efficiency - When casement windows are closed, they are the most energy-efficient of all window types. The casement window’s sash is able to fasten very securely when in a locked position - all four sides seal tightly; allowing for very little outside air to get in. This type of window is especially good to have in a very windy climate.

  • Superior Ventilation - No other replacement window offers as big of an opening for ventilation as casement windows. Depending on which side the window opens from, it can also act like a funnel catching and directing additional air into your home. 

  • Better Views - Since casement windows are one panel of glass, you have fewer window panes and parts obstructing your view. Fewer obstructions yield a clearer, more beautiful view for you to enjoy. 

  • Design Options - Casement windows actually come in a large variety of styles that will fit any style and make your home feel uniquely you. French style, side open, bottom open, push open, Colonial, and much more. 

  • Security - Casement windows feature hook-shaped casement locks embedded within their frames, which gives homes an added layer of security.

 

Casement Window Cons

Not every window style will work for every situation or location, here are the cons for casement windows.

 

  • Cost - Casement windows do tend to cost more than other window styles. Of course, size, style, glazing, and other factors will all play a role in the final cost of a window and should not be the determining factor when deciding on a window style. 

  • More Mechanical Parts - Casement windows’ functionality depends on mechanical parts including the latch, hinges, and crank. This means, when comparing a casement window to a slider, there are more parts for potential replacement and fixes down the road.

  • Size Limitations - Due to how casement windows are mounted, they cannot be very wide. Casement windows are not able to be used with window-mounted air conditioning units due to the safety issues.

  • Not Screen Friendly - Casement windows allow for a lot of ventilation but without a screen, that could also mean an increase in bugs and outside debris.

 

Double Hung Window Pros

Double hung windows are the most popular and commonly used window style. The many benefits explain why.

 

  • Versatility - Double-hung windows are compatible with most home styles and they come in a variety of shapes, sizes, and stock colors. 

  • Easy to Clean - Newer double hung windows have tilt-out upper and lower sashes (the part of the window that holds the glass). This makes the windows easier to clean. Many manufacturers also offer windows with removable sashes for even easier cleaning.

  • Energy Efficiency - Although precise measurements are required to minimize moisture and air leaks, high quality double hung windows have the option of quadruple weatherstripping. This feature prevents heat from escaping and cold air from entering, eliminating the need to adjust the thermostat up.

  • Air Conditioner and Screen Friendly - Unlike casement windows, double-hung windows can accept air conditioners and screens. Because they slide up and down instead of cranking out or sliding to the side, they can hold AC units safely and screens can be added and removed when necessary.

Double Hung Window Cons

Even the most popular of the bunch has a con or two. 

 

  • Limited Ventilation - Double hung windows work by sliding the bottom sash up or the top sash down. This means, only half of the window may remain open at one time.

  • Possibility of Air Leaks - While replacing your windows with double hung windows will reduce air leaks, these windows are not the most airtight. Casement windows, which seal tightly at all four sides when closed, provide superior defense against air leaks. With double hung windows, it is a good idea to use interior weatherstripping as a barrier against air leaks. By weatherstripping windows, you can reduce the likelihood of drafts as the windows age and ensure your utility bills stay low.

Best Place for Casement Windows

Casement windows work very well in lots of different situations. 

  1. Home Office - Casement windows are the best window style for home offices, as its large glass areas allow more light in, creating a conducive work area.

  2. Bathroom - You probably never considered a casement window for your bathroom due to privacy concerns. Casement windows are versatile with several obscured glass options. They are especially useful when you need to quickly vent excess humidity. 

  3. Living Room - Casement windows can be installed without grids, making them a great alternative to picture windows when you want to get the most out of a view but don’t want to sacrifice ventilation. Casement window hardware allows easy crank operation and can withstand years of repeated use.

  4. Bedroom - The standard window for bedrooms has been a slider style (single or double hung) for as long as we can remember. While always a good choice, maybe you’d prefer to see more of your view or create more ventilation in your room. Casement windows are a great option.

  5. Kitchen - Casement windows are most commonly found in kitchens because they’re easy to operate and can be quickly opened in case you need to quickly air out the kitchen. The hand crank can be easily opened even if you only have one hand free. The increased natural lighting also makes preparing your dishes a lot easier.

Best Place for Double Hung Windows

Double hung windows are a great option for almost every window space in your home. 

 

  1. Bedroom - Double hung windows are great in any bedroom. They’re easy to slide open, provide good ventilation, and are easy to clean even on the second floor since the sashes tilt inward. 

  2. Living Room - Double hung windows are perfect for living rooms and any larger room where air flow and ventilation are needed. They’re easily customized with color and grid options that will make your room and your view look gorgeous. 

Double hung windows are very versatile, they could truly work in any room in your home. However, there are instances where a double hung is not the best option. For instance, you don’t want to place a double hung window over your kitchen sink since that reach can make opening and closing the window difficult. 

Summary and Next Steps

While the double hung window is the most popular window style out there, casement windows are a wonderful option in a variety of situations. Casement windows provide more unobstructed views and ventilation than the double hung window and are simple to open - even one handed. Both double hung windows and casement windows can be customized by size, color, and glass style to work perfectly in your home.
