Casement timber alternative window solutions

Marry modern technology with vintage aesthetics with these truly stunning timber alternative Evolution windows.

Sculpted beads, grained detailing and putty Ovolo Georgian bars perfectly replicate those features found on traditional timber windows.

More than that, the mechanics of Evolution’s casement provide slim site lines, thermal insulation and market leading security features.

With virtually no maintenance required, these beautiful products deliver A plus rating as standard, protecting your home against even inclement weather conditions.

Authentic and charming, a key characteristic of the Evolution storm casement is its closed position. The sash overlaps the outer frame, providing additional sealing and protection alike.

A full 10-year guarantee offers reassurance, along with the knowledge that your windows will be manufactured solely by Evolution themselves under strict quality control measures.

Windows are fitted by expert and accredited installers who round off a slick, rewarding process.

Evolution Storm Windows - Rococo

Safe and Warm

Evolution’s Storm Windows have undergone extensive tests to ensure they achieve excellent energy performance.

An A+13 energy rating and a U value of 1.3 help to provide a safe and warm environment for you and your family.

Evolution can further increase the performance of the window by introducing triple glazing or innovative acoustic glass solutions to help with the reduction and control of noise.

Home security is at the forefront of the development team’s thinking, which is why security features form an integral part of the overall design.


All products have been independently tested to current British and European Standards and as a result feature a wealth of high security features.

These mechanisms include multi-point shoot bolt locking systems and 3-point window locking systems respectively. To ensure these elements lend themselves to the overall design we ensure all steel bolts are silver finished for continuity. It’s the small details that make the biggest difference!

A full range of contemporary and traditional lockable handles are also available to provide your home with extra security.
