Timber Casement Windows - Simple, elegant and timeless

Our bespoke Casement windows are Secured by design and 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 are reforming an historic Grade II listed building or designing 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 casement window which sits proud of the frame, ensuring additional protection from bad weather. Our historic range is designed for listed properties and those in conservation areas. This includes putty style glazing, single glazing, narrow double glazing and vacuum glazing. If you need single glazing but also want ultra high acoustic performance, our range will deliver. 

We can offer thousands of colour options from the RAL Classic, Design and Effect ranges as well as NCS colours, We can also colour match to all leading manufacturers including farrow and ball and little greene.

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.

Our contemporary casement windows are incresingly found in modern settings. 

Our casement windows are designed to last decades with minimal maintenance and won't need to be recoated for at least ten years, most last a lot longer than this before needing painting. 

If you require acoustic windows, we have the largest range of performance tested options of all the leading timber window manufacturers and we test the whole window not just the glass. 

Our paint system is the only four stage system which guarantees longevity. Our windows will last at least twice as long as uPVC but much longer in most cases. 

Available in a choice of timber options, our casement windows are designed with drain and vented systems and internal beading. we often mix timbers using softwood for sashes and hardwood or accoya for cills and vulnerable areas. 

All our timber is FSC certified and is stored in moisture controlled conditions in our factory. 

We offer a range of profiles and trims which can be found in our options brochures and on our website.
