What is a flush casement window?

A ‘flush’ window is a traditional casement window style, where the window ‘sash’ sits flush against the frame. This gives the whole window a flat appearance, similar to traditional wooden windows dating from the 19th century, or earlier.

Our flush sash windows are made using modern, maintenance-free uPVC and A-rated double glazing, but still retain the authentic look of timber. This makes them the perfect windows for heritage properties or conservation areas.


Flush sash windows are typically more cost-effective than other window styles, meaning any homeowner’s additional budget can be invested elsewhere in the property. The cost-to-benefit ratio is always improving with casement windows, continually offering many modern features at a relatively low cost.

Low maintenance

Our flush sash windows are relatively easy to maintain during their lifetime simply needing a wipe down should they ever become dirty. They are also no longer susceptible to warping, discolouring or flexing, acting as a dependable and highly durable window style.

Thermally efficient

Benefitting from multi-chambered window profiles, flush sash windows are good at keeping the heat in and cold out. Various additional hardware can be incorporated also such as thermal breaks and additional glazing to ensure your windows always operate at peak thermal efficiency.

Energy efficient and well insulated

With the sash fitting flush into the window’s frame, our flush sash windows can achieve the pinnacle WER (window energy rating) of ‘A+’. This means that your newly fitted windows will never suffer from excessive heat loss and offer the maximum amount of thermal retention.

The energy efficiency of flush sash window act as only one of their many features. They are also available with 28mm double or triple glazing for further heat retention, internally beaded for added security against potential intruders and can even be fitted with a wide choice of opening configurations in mind. Georgian bars can also be added for increased authenticity.

The appearance of traditional timber

Although often fitted into properties that want to maintain traditional aesthetic, modern homes have a wide range of colours and finishes to choose from. This means your newly installed flush sash window can either bear a striking resemblance to timber or a uniquely finished design that adds a freshness to a traditional design.
