Casement Windows


What is a casement window?

Casement windows are the most popular windows in the United Kingdom and around Europe. Essentially a casement is any window that operates on hinges. Our casement windows offer great levels of heat retention and sound reduction, and are available with double or triple glazing. Since a casement window operates on hinges, there’s much more variation in design, so there’s something for everyone.

Should I change my casement windows?

Over time problems can develop with the hinges and handles. Double glazed units can fail and handles can become stiff and difficult to operate. If the glass has ever been cracked you can lose your Argon gas fill and so remove any heat retention capability. In general, if a window feels difficult to operate or if your home feels cold it may be time to look into some replacements. Luckily casements are some of the most cost-effective windows available.

Practical Design

A casement window is a great choice for the practically minded customer. Since they operate on hinges, they form a tight draught seal and are simpler to produce. They are cost-effective, versatile and can come in almost any size or shape. Our engineered timber frames are up to 60% stronger than regular timber and we can offer U-values as low as 0.74 w/m2k (when triple-glazed). Since the windows operate with a handle system, there’s a great deal of hardware to choose from. From more modern styles to traditional ‘monkey tail’ handles, which can really add a touch of elegance to your home. Multipoint locking provides a high level of security, with the sash secured into the frame at two separate points. All our windows are all produced using sustainably sourced timber and is certified by the Forestry Stewardship Council (FSC).

Other Options:

Until around the 16th Century, it was rare for ‘windows’ to be glazed, or framed, at all. Early windows were effectively just holes, with metal bars preventing unwanted access and timber shutters providing protection from the elements.

Simple glazed windows, as we know them today, started to become prevalent in the Tudor Period and were, in effect, simply glazed shutters that allowed for both light and protection from the elements simultaneously.

These side-hinged Casement Windows were the most common form of glazed window in Britain throughout the 16th Century, prior to the introduction of the Sash Window in the 17th Century. Early Casement Windows typically comprised of multiple small glass panes, held into place with lead, due to the limitations of the glass making techniques at the time.

In the 19th and early 20th Centuries, there was a resurgence of popularity in the traditional charm of Tudor properties and features, and Casement Windows once again became dominant in Britain. Thanks for several advancements in glass manufacturing these newer Casement Windows were often comprised of one or two larger glass panes secured into a timber frame with putty, although non-functional externally adhered lead lights were often used to replicate the original Tudor designs.
