Casement windows are one of the most popular styles on windows. They are most often found in kitchens as this is the traditional style with hinged sides. These windows can open inwards or outwards, but it is most common for them to open into the household while having outside shutters open away from the house.
One of the downsides to casements is the lever, crank, or cam handle that is needed in order to open the window, which is also used as a lock. Normally you will find casement windows have two windows next to each other but you can occasionally see some with single windows.
The title of earliest movable window, as well as the first window ever to be used in American households, goes to casement windows. It is believed that casement windows date as far back as the 1500s. The use of this particular type of window was prevalent in the 1800s in Europe as well as America, but slowly declined in the early twentieth century due to the creation of the sash window. However, casements are making a comeback.
These windows normally have a metal or wood framing. Ones with hinges at the top are called awning windows. They have been given this name as the open out in a similar way that awnings do. Hooper windows are another style of casement windows that are popular. They are the opposite of an awning window, with hinges on the bottom. Hopper windows open out, in a similar way to a drawbridge.
These windows were quite small when they were first invested, this is due to the lack of material available in the 16th century. However, things changed as time moved forward and the windows market changed after the invention of cylinder glass. This invention allowed for larger and thinner windows. Cylinder glass, combined with a hunger for more modern looking windows, allowed for the creation and popularity of the sash window.
Sash windows were at their height of popularity in the 21st century in America. Sash windows are not without their problems, there are issues with maintenance and their opening mechanism. This is probably why casement windows are making a comeback. Casement windows are now one of the leading windows in the UK and the rest of Eurpoe.
