Casement Windows and Their Energy-Efficient Properties

Casement Windows and Their Energy-Efficient Properties

October 17, 2018

The casement window is one of the most popular options for replacement windows on the market today. This classic window style combines modern functionality with the traditional aesthetic. Its simplicity can give any part of your home a charming look. Moreover, it is an energy-efficient alternative to other window styles.

Casement Windows and Their Energy-Efficient Properties

This article explains the features that make up this window and its overall role in ensuring indoor comfort and energy efficiency for your home.

Ease of Operation

Casement windows are similar to other operable replacement windows like the double-hung and sliding types. While double-hung windows are lifted upward or downward and sliding windows move on a horizontal track, casements have sashes that open outward with a turn of crank, lever or handle. Such hardware is often found either in the middle or near the bottom of the sash.

Standard casement windows utilize heavy frames and full weatherstripping around the perimeter. It also helps that the included hardware also serves as a lock. This holds the sash in place when closed. Aside from better security, the tight seal resists the entry of drafts into your home. This improves your energy efficiency further, limiting your use of heating and cooling during winter and summer.


A prominent quality of these windows is their ability to provide enough ventilation for your home. Just swing open the sashes and let air in. You also don’t have to worry about strong gusts of wind, because the hinges hold the window in place. In addition, the angle of the open sash catches side breezes, something that no other window style can do.

More Lighting

The expansive glass area of casement windows helps frame your outdoors, as well as allowing natural light into your room. Fortunately, the glass used in today’s windows are spectrally selective, which means that some wavelengths can only enter. Here, natural light passes through the window while blocking out harmful UV rays that would otherwise heat up your indoors.

Hear From Our Customers

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!
