Beautiful Windows, Tailored by You

At Evolution, we have always set out to be pioneers in modern window design and development and are widely considered to be the most innovative and quality driven company in the industry.

We blend specialist knowledge with the finest materials and craftsmanship to realise the ultimate next generation in window design. Our windows take design inspiration from the beautiful aesthetics of timber but without all the drawbacks of the time-consuming maintenance and costly upkeep associated with wooden windows.

Traditional Features

With all the beauty of traditional timber, our windows have to be seen to be believed. Featuring timber look joints, traditional internal timber aesthetics, deep wood-like cills and discreet ventilation, we take the best from the past and create the most advanced A+ rated products that help enhance and protect your home now and for years to come.

Whether Georgian, Tudor or Victorian, whatever the architectural style of your property, we can create a window to suit. Every window we make is completely bespoke and can be designed with Georgian bars, leaded panes or even stained glass to recreate the exact look you require.

Timber Effect Joint

We strive to find the best balance between old and new and find that taking the best elements of each yields the most perfect results. By taking traditional styling and bringing it into the 21st century, we manufacture products that fit today’s busy lifestyles, allowing our customers to get the look they desire, as well as the practicality they need.

All our windows are hand crafted with timber effect joints to give an authentic wood look to all our Storm and Evolution Flush windows. This expertise and dedication is what sets us apart from other window manufacturers, along with our passion for hand finished.

Acoustic Glass

A key criteria for new windows is minimising sound. There is a comfort in knowing that when you close your windows you are closing out the outside world too. Therefore, we offer an acoustic glass option for both our Storm and Flush window ranges that can reduce the external noise levels you hear inside your home by up to 30%.

In simple terms, acoustic glass is a laminated glass which has a noise reduction interlayer not found in standard double glazed units. This layer significantly reduces the amount of excess noise from external sources such as railway lines, roads, air traffic etc without compromising on light transmission or the energy performance of your windows. If you value a peaceful life from external noise, this is definitely worth considering.

Energy Performance

Did you know that over a third of heat can be lost from your home thorough inefficient windows? Evolution’s window ranges have always been one of the most energy efficient choices available in the modern window marketplace. Both A+ rated as standard, the Storm and Flush window ranges take energy efficiency to the highest level with double glazing to 28mm thickness.

The Storm window range has a 1.3U value and is rated WER A+13 as standard and the Flush range also has a 1.3U value and a rating of WER A+11 as standard so you can be sure that choosing any windows from the Evolution range will keep your home warm in winter, cool in the summer and keep your bills to a minimum, knowing you are not wasting or losing energy.

Furniture & Accessories

We have a wide range of both traditional and contemporary style window furniture available. You can choose from various colours in our standard range, solid colour contemporary 360 or teardrop handles from the Ventiss range or the more traditional monkey tail or bulb end handles.

For the more adventurous, you’ll love our mixed finish Ventiss Designer range where you can mix and match handle finishes. There are 5 colour combinations available in both the teardrop and 360 handle options to choose from. Many of our handles are available with matching working or decorative peg stays.

Protection and safety is important to everyone; therefore we place great emphasis ensuring that our windows are as secure as possible.
