BOWED SASH WINDOWS & CURVED SASH WINDOWS
Elegant bowed sash windows, curved sash windows, casement windows and doors are a key feature on many Georgian and Victorian properties. Sash windows with curved tops (see above) are an elegant feature of many Georgian homes, while bay windows featuring bowed sash windows (see gallery below) started to become more popular in the Victorian era.
Creating bowed and curved windows and doors for period, conservation and listed buildings requires a high level of expertise, as they always have unique dimensions and need to be handmade-to-measure. It is even more of a challenge to upgrade the performance and efficiency while matching the original design.
From the classic ‘bicycle wheel’ design of Georgian sash windows (see above) to the arched windows of Gothic Revival architecture in the Georgian and Victorian eras, curved and bowed windows have been an elegant part of British architecture throughout the ages.
In terms of design, the upwards or outwards curve on the sash window, casement window or door must perfectly match the curve of the frame. Within a bowed window, some manufacturers such as Timbawood will also offer the option for each pane of glass to be bowed. This is possible using the more traditional technique of glazing a window with smaller individual panes of glass that are joined with solid glazing bars, rather than the more modern technique of using one larger pane of glass, which wouldn’t work with bowed glass.
At Timbawood, our finest heritage windows and doors can be individually glazed with bowed glass and even hand puttied and hand painted, as they would have been in Georgian and Victorian times.
Our windows and doors are as unique as the properties we create them for, and any curved or bowed design can be made with a range of finishes and glass choices, including single glazing or our specialist ‘Timbalite’ slimline double glazing, that looks just like single glazing but has all the benefit of double glazing.
At Timbawood we specialise in bespoke timber windows and doors for period, conservation and listed properties, and our single glazed and double glazed windows have been approved for listed properties by planning authorities throughout London and the South East. Whether you’re looking for sash windows, casement windows, french doors, fire doors or bifold doors, please get in touch with one of our experts if you would like advice or a quote for your listed, conservation or period project.
