What Are Casement Windows and Double-hung Sash Windows?

It can be a little bit confusing to discuss pros and cons without some definitions on these two types of window:

  • What is a casement window?: A casement is a type of window that has hinges on the side, where it attaches to the frame. They may open inward or outward, but usually outward.
  • What is a double-hung sash window?: A double-hung sash window is a design with two sashes, which slide up and down. A single-hung sash window has the top sash in a set position.

The essential difference is that a casement window is one that usually opens using hinges on the side, whereas a double-hung window uses sashes at the top and bottom of the window to open.
