The Evolution Flush and Storm timber alternative range has been designed to emulate the beautiful aesthetics of traditional timber windows but without the drawbacks.
The 82mm outer frame is wide enough to give traditional timber styling and accept a working peg stay, and narrow enough to fit into window openings without cutting back plaster lines (subject to existing building/survey).
Despite the fact that it is the slimmest timber alternative window available – the thermal performance is outstanding, achieving an A+ 11 rating with a u-value of 1.3 W/m²K.
Due to the bespoke nature of these items and the wide colour range available we strongly advise viewing the options before you make any decisions. We can arrange this by appointment at our showroom in Bracknell, Berkshire where we have a number of Evolution windows and doors on display.
Unlike all other composite and uPVC window companies, Evolution does not supply profiles to other fabricators or manufactures. Every window and door is manufactured in their own factory, meaning that they have ultimate quality control. Evolution is, quite literally, a hands-on company. It’s what sets them apart from other manufacturers. They combine traditional manufacturing techniques with modern materials to ensure that their products look authentic and for many years to come.
It’s the attention to detail that makes Evolution windows so exceptional.
The most unique, advanced storm-proof window available. The sash has a very low profile with a small round edge, so avoiding the ‘chunky’ appearance of other lipped / storm timber alternative options on the market. It is the only rebated casement on the market with a timber joint.
The Evolution flush casement is the perfect choice for a traditional home and is now also very popular for contemporary designs due to the flat clean lines. The sash / casement sits flush with the outer frame, showing more outer frame and making the casements slimmer. The authentic grained wood finish fits in well with ‘tired’ surroundings, a perfect maintenance-free option with no compromise on style or character.
The Evolution timber-look butt joint has the best of both worlds; the strength of a welded joint on the inside, with the look of a mechanical joint on the outside. Handcrafted to perfection!
The Evolution Georgian bar is handcrafted to fit perfectly over the glazing bead. The exterior detail looks like a putty line. The interior is an ovolo and is available in 20mm and 36mm options.
Evolution is the only timber alternative window on the market to have developed a sill that truly replicates timber. The sill is 45mm deep with a complete end cap. The Evolution outer frame on both Storm 2 and Flush is simply beautiful. It has been modeled to perfectly duplicate a traditional timber window. It has a delicately small ovolo achieving a wider flat surface area to the transoms and mullions. The 82mm depth of the frame allows a fully working peg stay. It is virtually impossible to detect that this is not a timber frame!
Evolution offers 10 timber alternative finishes and one smooth gloss finish. It’s also possible to have any RAL colour using a special Kolorbond paint finish. White Grain is a soft white (RAL 9010). Agate Grey and Olive Grey have a green/grey tone. Anthracite Grey (RAL 7016) is popular for contemporary designs. The Natural Wood finish is unique to Evolution. All colour finishes are exterior with White Grain on the interior as standard, or you can choose any of the colours for an interior finish.
