Sliding Windows and Casement windows are both great options for any home, but there are some differences between the two windows:

Physical Differences

When it comes to your home’s replacement windows, the dimensions of your window opening will influence your decision. Sliding windows are used in openings that are wider than they are tall. They open sideways, with one pane sliding over the other. Casement windows, also known as crank windows, are often chosen for tall, narrow window openings. The windows are attached to the side of the window frame and swing outward. Casement windows are opened and closed with a crank, handle or lever.

Window Ventilation

There is a difference in how air flows through the openings, based on how each window type is built. Most casement windows open completely, so air can pass through the entire opening. With typical sliding windows, half the window space is closed or overlapping, so the windows provide less ventilation. Stanek® sliding windows, however, are built to allow both panes to be opened at the same time, allowing for maximum ventilation from a sliding window.

Energy Efficiency

Both replacement sliding and casement windows are energy efficient, but there is a difference between the two options. Since you have to be able to open a sliding window, the seal must be somewhat flexible to allow the window to open and closed. A casement window seal is not flexible. While both replacement window options are energy efficient, casement windows are more energy efficient since they are not flexible by design.

What to Look For In Quality Sliding or Casement Windows

The opening you have for your window space will help you determine what type of replacement window you need. When you are looking for replacement windows, make sure the company you choose has quality windows and will provide you with all of the information about your new windows.
