What is a casement window?

What do we know about casement windows? And why might self-builders or homeowners choose casement windows for a property?

What are the key characteristics of a casement window?

Casement windows, sometimes referred to as side hung windows, are formed of hinges or pivots that are typically attached to the upright side of a frame so that it opens along its entire length, either inwards or outwards, in a similar manner to a door.

Over the years, casement window designs have evolved significantly, their size, shape, and overall design can tell a lot about the time during which it was made. The classic casement dates back to the 16th century, a time when the manufacturing of large glass panes was an extremely complex process. Many early casement windows consisted of a cast iron frame with lead lattice patterns adjoining lots of smaller glass pieces. During the Victorian period, it became more common for casement frames to be constructed almost entirely from timber and adorned with fashionable shutters.

Globally, stylistic variations can also be found, with traditional British and German casement window designs typically opening outward, while the French casement window generally encompasses two inward opening sections, carefully crafted without a centre post (mullion) to offer an unobstructed view. In the United States, French casement windows were developed even further to form a French door or casement door design which grants access to outside balconies or patio areas.

Why choose casement windows?

Casement windows are an ideal window choice for housebuilders and developers seeking to encompass a classic design made using modern materials and manufacturing processes when working on traditionally designed projects.

For restoration or renovation projects, especially those situated within conservation areas, listed buildings or period properties; a genuine timber casement window that is in keeping with the surrounding architecture may be the only suitable option.

While there is a common belief that timber windows are high maintenance, a product made from engineered wood such as Accoya® will result in a timber casement window offering superior performance and a beautiful finish.

As well as being non-­toxic, Accoya® offers incredible insulating properties and is able to withstand extreme external environments, it is also a hardwearing and versatile material that can be stained or painted to create the desired effect and a plastic replica will simply not be able to achieve the same results.
