Our Guide to Casement Windows and Sash Windows 
We Restore, manufacture and design many types of windows, our main focus has always been to make sure our customer receives their order exactly as they desire. We provide both restoration and the manufacture of high quality wooden Casement windows.
So by now you may be wondering; is there really such a big difference between Casement and Sash Windows?  Well, yes there is a huge difference in design and even restoration process - Let's just go through exactly what each Window is like.
What is a Casement Window?
Casement Windows or just simply – casements, are a type of window that is attached to it's frame by hinges on the side of the frames.
If there hinges are at the top then the window is called an awning window and at the bottom, a Hopper window!
Casement windows were used long before Sash Windows were introduced and more often than not the glass panes were held steady with strips of lead. Some countries in Scandinavia still use these type of windows and have been the standard for many centuries.
What is a Box Sash Window?
Sash Windows are designed using one or more movable framed panels that each holds one or numerous panes of glass.
Sash windows tend to open vertically or horizontally in a style known as a Yorkshire Light.  The oldest surviving Sash Windows were designed and installed in the late 17 century and even windows from that era can still be restored without the need for entire replacements to be done.
Sash Windows are normally found in Georgian and Victorian properties and have the standard three panes of glass across and two up on each sliding panel.
