Casement Windows

Casements are a specific type of window which are directly attached to its frame using one or a few hinges. The term casement window is used to describe the specific position of hinges located on the side. Awning windows are windows which are hinged at the top. On the other hand, windows which have been hinged at the bottom are referred to as hoppers. They can be used either singularly or in pairs using a common frame which are usually hinged on the outer corners. A casement stay is commonly used to hold casement windows open.


Casement windows were very popular in the United Kingdom before the discovery of the sash window. It was the most common house window used by the country. In the past, casement windows were made up of leaded glass. They were glass panes which were kept in place by strips of lead. The casement windows were also hinged on their side and they open in an inward motion. There were functional exterior shutters which covered them and these shutters open in an outward motion. To this day, a wide variety of casement windows remain popular in most European nations. The two most notable countries who widely make use of casement windows are Sweden and Denmark.


Casement windows can be opened using a variety of methods. The most common ones include a cam handle, lever or crank. The cam handle is specifically placed in an area with hand height. It is also usually placed at the bottom and is used as a window lock. If the window is required to be opened outward, a stay, crank or friction hinge is needed. They effectively hold the window in the proper position amidst any strong winds or extreme weather conditions. The glass panes are usually put in a rabbeted frame which is sealed using a grazing compound or beveled putty. Its main purpose is to keep the glass securely in place.
