Flush casements are increasing in popularity but what exactly does the term ‘flush casement’ mean? The easiest way to explain it is that when the window (or sash) is closed, it sits flush within the frame, creating a flat surface on the outside. A lipped casement window is the more widely known design today. This is where the sash overlaps the frame when closed.
Flush casements are actually a very traditional window design and have been used for over 200 years. Dating back to the 19th century, all windows, which would have been constructed using timber, were designed with flush fitting sashes and this is evident in many late Georgian, Victorian and Edwardian properties.
More modern timber windows of the 1950s and onward were designed as lipped casements, as above. This trend continued with the emergence of replacement windows and double glazing. Whilst timber windows have always provided an option for flush casements, the more maintenance-free window types have not. This has now changed and over the last few years a number of flush casement options have been developed. Now uPVC windows, timber-alternative windows, aluminium windows and of course timber windows, are all available as flush casements. The clean, square lines mean they can look good in all property types, from traditional to contemporary.

You can choose lead or Georgian bar designs for a traditional look, or for a more modern appearance, a clear glass design means a larger glazed area and more light. Flush casements are available in either double glazing or triple glazing, subject to what type of thermal performance you are looking to achieve. Options on finishes and colours, both externally and internally, as well as a range of handle styles and optional peg stays mean that the flush casement window is extremely versatile.
