Infinity Flush Sash

Designed to replicate the appearance of timber, Flush Sash windows are distinguished by sashes that close into the frame and finish flush with the face of the window. Flush Sash windows typically have frames that appear the same width, known as “equal sightlines” this look is achieved using dummy sashes, something that undoubtedly improves the overall appearance of your property. Our Infinity range of flush sash windows and doors combine the elegance and style of traditional timber with all the benefits of PVC-U. This range is ideal for those who wish to add or improve the period features to their homes. Its unique, unrivalled, aesthetic appeal makes this range the most attractive suite of windows and doors on the market today.

Manufactured using REVOLUTIONARY GRAF WELDING TECHNOLOGY offering seamlessly smooth timber-style joints for a more authentic look. This innovative smooth corner weld design lets you make a distinct style statement, the Flush Sash window is the revolutionary new choice for all homeowners that wish to install PVC-u windows and doors.

Our wide variety of hardware options allow you to add the perfect finishing touch to your Infinity windows. All our Infinity Flush Sash windows come with contemporary handles as standard, but these can be enhanced with our Premium Furniture range which includes a Dummy Stay and Monkey-tail or Teardrop handle – all available in a choice of finishes.

Our Heritage colour collection has been specially designed to help you put together the perfect colour palette for your home. Our beautiful range of colours take inspiration directly from nature to harmonise perfectly with your home and its surroundings, ensuring it stays looking good for years to come. A unique range of woodgrain foil colours in 26 colourways from stock, complete with matching ancillaries, trims and accessories.


There’s no compromise when it comes to security. The bespoke locking keep has a useful night vent locking position, which gives great ventilation whilst maintaining your security. Our wide range of modern, contemporary and period style windows incorporate the latest built-in safety features, including internal glazing beads and multi point locking systems. To provide enhanced resistance to forced entry our windows can be fitted with a hinge protector device between the frame and the sash opener. Anti-bump, anti-snap key locking cylinders can be installed on all our doors to further enhance their security.



To keep out the wind and rain we use our patented high performance, multi-functional weatherseals. The airtight seal this creates helps to maintain your comfort inside your home. The Flush Sash dual seal is exceptionally watertight, with the added benefit of concealing any hardware. Any water that has found its way inside is quickly evacuated due to the intelligently designed integral drainage gutter.



Flush Sash windows look great in any surrounding, from country cottages to modern townhouses. Their subtle charm and elegance will transform your home. If you live in a Conservation Area, home improvements such as replacing your windows and doors will require planning consent as there are strict guidelines to ensure that architectural features are preserved. We have designed the Flush Sash Window and Door Collection with this in mind; replicating the appearance and style of traditional timber windows with features such as our authentic Wood Grain Finish, Monkey Tail Handles and Georgian Bar options. However, you should always obtain consent from a planning/conservation officer before proceeding with an installation.
