Casement windows are standard in millions of homes but ours are anything but ordinary. Available in a wide range of shapes, styles and sizes, with or without glazing bars in any colour you can think of, they offer exceptional performance and beauty in equal abundance. Whether you live in an historic Grade II listed building or a contemporary new build, an Edwardian terrace or a medieval church conversion, our casement windows can be designed to match your requirements and that of the planning/conservation officer.
We offer two versions of casement window – flush casements (or traditional) where the window or sash sits flush to the frame and stormproof which sits proud of the frame, ensuring additional protection from bad weather.
Both versions are very popular in the UK and if you are unsure which to choose then speak to one of our team for assistance.
As well as a endless colour options, we can also provide traditional butt hinges rather than friction hinges if you prefer a more traditional aesthetic.
If you fancy the look of a regency sash window, but need a more budget friendly option, we can offer regency mock sash casement windows, finished with decorative horns to provide an authentic sash window appearance. For practical application we have a wide choice of hinges including egress, restrictor and reversible.
