Flush Windows
Flush casement windows are a modern take on the classic casement style, with glass panes that sit neatly flush within the frame for a clean, streamlined finish. Combining timeless design with modern performance, our flush windows are available in both double and triple glazing options to deliver outstanding insulation, security, and long-term efficiency.
Designed to be secure and durable, these windows can achieve up to A++ energy ratings depending on your chosen glazing specification. Choose from high-quality timber or uPVC frames and customise the glazing, configuration, hardware, and colour to perfectly suit your home.

What are Flush Windows?
Flush casement windows can be top-hung or side-hung, and when closed, the sash sits neatly flush within the frame for a smooth, seamless finish. In comparison, traditional casement windows usually have a slight overlap (lip) that sits over the frame when shut.
Excellent energy efficiency
Save money on your energy bills with flush double glazed windows that come A-rated as standard in wood, or up to A++ in triple glazed uPVC.
Security you expect
Flush casement windows deliver the security features you expect of modern replacement windows. These include shoot-bolt locks, key-locking handles and toughened glass.
Conservation area friendly
The design of a flush window meets the requirements for most conservation areas in the UK. Customise in colour, glazing, and design to ensure they fit the aesthetic of your home and its surroundings.

Your Questions on Flush Windows Answered by Us
Are flush windows or casement windows better?
For many, traditional casement windows have historically been the most popular style of window, which come in uPVC, wood and aluminium. However, Flush casement windows share many of the same attributes, and are an increasingly popular choice for homeowners looking for an alternative contemporary style.
Are flush windows energy-efficient?
Flush casement windows are a fantastic energy-efficient option. Our uPVC flush casement windows come A+ rated as standard and A rated in wooden. Customise your windows to improve their energy performance, and explore the benefits of upgrading to A++ rated triple glazed flush windows.
How much do flush casement windows cost?
How much a flush casement window costs depends whether you choose uPVC or wooden frames. The cost could also increase if you look at the higher A++ rated triple glazing option. Our windows are made to measure for your home, so the best thing to do in order to get a cost is to book a remote quote.
Should windows be flush with my house?
Windows do not need to be flush with your property. Many window styles stand out from the main fabric of a house, like bay windows. Flush windows can be found in historic buildings across Britain. Modern flush windows combine that history with style, energy efficiency and security to appeal to almost any home.
Are flush casement windows suitable for conservation areas?
Flush casement windows can work for conservation areas so long as they fit with the property’s style. It’s always best to check with your local planning authority before replacing windows if your home is in a conservation area. It is more likely that they will meet conservation area criteria if they are in timber rather than uPVC.
Can I customise the colour and finish of flush casement windows?
At Anglian, you can choose from a wide range of colours and your finishes for your flush casement windows. uPVC windows come in multiple colours and finishes, while flush wooden windows are available in 200+ RAL colours plus our standard colour range.
