Flush Features & Benefits

Windows, redefined.

The Key Features of Flush Windows

The Evolution Flush window is a superb addition to the Evolution Collection. Our Flush windows are ideal for period properties who want to replace traditional timber flush windows with a high performance, equally beautiful alternative. Due to their fuss-free simple design, they also look excellent in more contemporary properties as well, making this a truly versatile window choice.

Showcasing sleek window lines that fit flush into the window frame, unlike stormproof windows that overlap the frame. This gives the Flush window a simple and elegant aesthetic. Originally, all windows were flush-fitting, it was the main window style until modern windows were introduced. Until recently, flush-fitting windows were only available in timber, so we challenged our innovation team to create a modern flush window, with stunning results.

Here are just some of the many reasons why discerning homeowners choose Evolution Flush windows:



Features & Benefits

Window aesthetics heavily inspired by traditional timber styling. Deep timber cill and timber-like proportions across the frame.  The Evolution Flush window is ideal for those wanting to replace original flush casement timber windows, or aspire to achieve the look of timber windows. The Evolution Flush window really does look like timber, and it’s difficult to tell it apart from real timber. 

Flush delivers an exceptional energy performance of A+11. With triple glazing optiond also available.  The heat generated in your home will not be able to escape with the highly energy rated Flush window. Your bills will reduce in cost and your house will stay warm and cosy for years to come. You can even have triple glazing to reduce noise and conserve heat. 
Slimmest window available with a greater glazed area.  Let more light into your home with the Evolution Flush window, without compromise. 
Exquisite wood detailing across all of the frame.  With the Evoltution Flush window, you can achieve the look of wood, but without the laborious sanding and painting every 5 years. The Evolution wood-grain effect laminate ensures a seamless finish and a maintenance free window. 
Discreet trickle ventilation via our unique weather bar.  Trickle vents can be an unsightly, but sometimes necessary addition to replacement windows. Evolution have developed a weather bar that sits over the trickle vents on the outside, keeping them hidden from view, so your beautiful new windows will look their very best whilst still being practical. 
Available in a range of standard colours and in over 200 RAL colours.  Having a wide colour range to choose from, you can have the exact finish you desire. You can even colour match your new Storm 2 windows to an existing colour – suitable for conservation areas.
