Even better than the real thing.

Evolution windows marry modern technology with old-world charm. Advanced production techniques mean they look exactly like solid wood, with every detail of the grain faithfully reproduced. They also replicate the joints and other details of traditional handmade timber windows. Without a magnifying glass, it’s almost impossible to distinguish them from the real thing. But in fact, they’re made from UPVC, which means they’ll give you many years of trouble-free service, and require no painting or other routine maintenance.

Designed and manufactured in the UK, Evolution timber alternative windows offer unrivalled energy-efficiency, exceptional weather proofing and tremendous value for money. Available in two traditional designs, these amazingly versatile, high-quality windows are suitable for homes of all ages and styles.

Windows for all seasons and all homes

Tradition meets technology in Evolution timber alterative windows. With their detailed wood grain effect frames, Georgian or Victorian bars and perfectly reproduced timber detailing, they’re prefect like-for-like replacements for your old wooden windows; ideal for period properties, or if you’re in a conservation area. At the same time, you can enjoy the modern benefits of high energy efficiency (Evolution double glazing outperforms many triple-glazed windows) exceptional weatherproofing and low maintenance.

Evolution windows are available in two different styles, so you can choose exactly the right windows for your home, whatever your location and personal preferences.

Evolution Storm 2 Stormproof Windows

The Stormproof Storm2 window combines traditional joinery methods and intricate detailing with state-of-the-art technology. It’s supplied with energy-efficient A+13 rated double glazing, with the option to upgrade to triple glazing or soundproof acoustic glass if you wish. The hinges are designed for easy cleaning and fire escape, while multi-point shoot-bolt security locks help ensure your safety and security.

Evolution Flush Windows

Evolution Flush Windows perfectly replicate the beauty of traditional timber windows. With their sleek, flush-fitting frames, they’re simple and elegant, and a perfect match for period and contemporary homes alike.

Glazing options to suit your personal requirements

Not only do Evolution give you good looking, low maintenance timber-effect frames which are almost impossible to tell from real timber, but you can also choose from several glazing options to give you maximum energy and noise efficiency.

Double Glazing

Evolution windows have always been among the most energy-efficient available, and the Storm 2 and Flush ranges are no exception. Both are A+ rated as standard, and double glazed with 28mm glass, helping to keep your home warm in winter and cool in the summer, and your heating bills under control.

Triple Glazing

Having triple glazing in your Evolution windows raises their energy efficiency, or U value, making them 15% more efficient than double glazing in terms of heat loss.

Glazing Designs

Georgian bars

This traditional window style is still extremely popular, and with good reason. Evolution’s single 36mm mid-rail design is now available for larger windows, and suits both period and contemporary properties.

Leaded glass

Idea for period properties or a traditional look. You can choose from plain, coloured and leaded glass options, as well as opaque glazing for bathrooms, entrances and other rooms requiring privacy.


All the colours you can think of

Evolution windows are available in white, traditional wood effects or a range of custom colours to suit your home, surrounding area and personal taste.

Timber effect finishes

With their intricate timber grain detailing and realistic timber colouring, Evolution windows are almost possible to tell from the real thing, even when viewed up close. Choose from 10 standard finishes that replicate the most popular wood types to perfection.

Standard paint finishes

Evolution windows are available in smooth white gloss finish as standard, to suit a wide variety of houses. If you want something more individual, or to match an existing colour scheme, the Kolorbond system gives you a choice of over 200 paint colours, mixed to your requirements.

Finishing touches

When replacing your windows it’s the details that make all the difference. Evolution’s attention to detail extends beyond frames and glazing to handles and peg stays – and items you can’t even see!

Handles & peg stays

As well as the traditional ‘monkey tail’, you can choose from a handles styles, including teardrop, designer, curve and standard; finishes include hammered black metal, pewter, chrome and gold.

Designed to match your handle choice, peg stays are available as a fully working option or purely as decoration.


For complete peace of mind Evolution windows are fitted with multipoint shoot bolt locking and centre casement locking with opposing bolts.

Noise Reduction

You can specify acoustic glass as an option on Storm 2 and Flush windows. This special laminated glass has an interlayer that can reduce external noise by up to 30%. Ideal if you’re living near a busy road or railway, under a flightpath, or just value your peace and quiet.
