A Modern Take on Tradition

Flush sash windows are a beautiful window option, drawing inspiration from traditional timber joinery to bring an authentic period look to your home. Further to this, they are manufactured using a market-leading profile to ensure they achieve contemporary standards of thermal efficiency, PAS 24 security, durability and design.

The flush sash window is essentially a casement window, with a sash that replicates the look of more traditional windows by sitting flush within the frame. They open out and are internally glazed. They are available in a wide range of colours, and with a selection of traditional and modern hardware options, to make sure they are well suited to modern and traditional homes alike.

Features & Benefits

Frame Options

The uPVC flush sash window utilises our decorative profile with two frame options. The standard frame is 55mm across the large face and the large frame is 70mm on the large face. Both frames are 70mm deep. All sashes and frames are fully welded and the transom and mullions are mechanically jointed to retain the traditional timber look. All flush sash windows come with dummy sashes.

Hardware Options

Our stylish inline locking handle is available in White, Gold, Satin Silver, Chrome and Black. For a traditional look ask for our monkey tail handle and monkey tail stays. The standard friction stays can be upgraded to Fire/Easy clean and restricted hinges. Alternatively, any of these friction hinges can be coupled with a restrictor catch. Espag locking is fitted as standard with the option of security locking, hinge protectors and PAS24.


We offer a range of security specifications and options. Our uPVC flush sash windows have been fully tested and certified to PAS24, which is not only suitable for new build and new extension projects, these flush sash windows will bring peace of mind to the most security conscious.

Stylish Colourways

Choose from an extensive range of wood grain foils to add a classic touch to your flush sash windows and enhance the look of any type of property. Our fast track colours include Rosewood, Golden Oak, Anthracite Grey, Black, Cream, and many others. Alternatively, incorporate the woodgrain foils on the outside with the standard white on the inside. The Heritage woodgrain range and special order colour options give a multitude of choices to suit your customer’s taste. We can also supply matching ancillaries trims.

Energy Rating

Our flush sash windows achieve a ‘B’ window energy rating with the British Fenestration Energy Rating Council (BFRC) as standard, with the option for upgrading to an ‘A’ rating by adding Argon gas. The four-chambered profile and thermal composite insert offer superb insulation for year-round comfort.


An extensive range of accessories is available to complete your flush sash window installation requirements. These include 95mm, 150mm and 180mm cills, 15mm, 25mm, 40mm, and 70mm frame extensions. With a 2mm joiner or 15mm steel reinforced joiner, along with a 90° corner post, 135° fixed bay pole and variable angle bay assembly, joining frames together couldn’t be easier. Trickle vents can be fitted in the frame with our standard colour options, and colour matched trickle vents are also available.

Thermally Efficient

With modern performance and design in mind, all of our flush sash windows utilise a thermally efficient profile to help increase the overall heat retention of the home. Not only does this mean that your customer will remain comfortable throughout the colder winter months, it also means that they could find themselves saving money on their energy bills as they rely less on their heating throughout the year.
