Single- and Double-sliding Windows: Which Ones Should You Get?

Sliding windows come in two configurations: single and double. While they may seem similar or even interchangeable, there are actually subtle differences between the two. If you are thinking about installing a set of sliding windows in your house, here’s what you need to know. 

Single and Double-sliding Windows

The Benefits of Sliding Windows

Sliding windows are a favorite among homeowners and window installers alike because they are easy to install and require very little maintenance. They are also great windows to have if you want to let in plenty of natural light. Unlike double-hung windows, sliding windows open horizontally with sashes that easily glide back and forth rather than up and down, making them ideal for people with mobility issues.

Single Sliders

If there is an area in your home that can benefit from extra airflow, then single-sliding windows may be what you need. In this configuration, one panel slides while the other remains stationary. Your window replacement contractor may recommend single sliding windows if you are working on an area with a smaller width. 

Double Sliders

Double sliders, on the other hand, have the advantage of improved airflow because they can be opened from both sides, giving you more control. You can open either the left or right side to catch a slight breeze, or both at the same time. This may be a better option if you have a particularly wide space. 

No matter which style you choose, think about how you want to direct airflow into the room as well as how much room on the wall is available.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
