What Are Evolution Windows?
Evolution is a British manufacturer of bespoke timber-alternative windows. Evolution states that its products are handcrafted in its Biggleswade factory, with a focus on timber-style detail and modern window technology.
The Evolution window range covers six routes for Bowalker customers: Storm, Flush, Contemporary, Georgian, Leaded and Bay. Storm is a stormproof casement inspired by cottage and period windows, now in its second generation as Storm 2. Flush gives a simpler line where the sash finishes level with the frame for a cleaner traditional appearance.
Bowalker installs and replaces Evolution windows across Sussex and Surrey, specifying the right style around the property, existing window pattern, required hardware and finish choice.

Why Bowalker Installs Evolution Windows?
Bowalker chooses Evolution for homeowners who want the appearance of timber but do not want the repainting cycle, rot risk and upkeep that come with natural wood. Evolution earns its place for a few clear reasons:
Bowalker customers continue to rate the company highly, including 9.67/10 on Checkatrade, and the same in-house standard is used on Evolution installations.
Evolution Window Styles Available from Bowalker
Evolution window style choice depends on how much traditional frame character the property needs. Each style is a timber-alternative uPVC window, but each creates a different line from outside.
Storm
A stormproof casement with a sash that overlaps the frame, taking inspiration from traditional cottage windows and older timber detailing. The current generation is sold as Storm 2.
Flush
A flush casement where the sash finishes level with the frame, giving a cleaner line for period homes, cottage replacements and newer properties.
Contemporary
Georgian
Leaded
Bay Window
A bay window arrangement that projects from the elevation to add light and space.
Colour and Finish Options Available
Evolution finish options are designed to make uPVC look closer to painted or grained timber. The range includes foiled woodgrain effects, smooth finishes, standard coloured foils and architectural RAL colours.
The finishes Bowalker supplies include:
Foiled woodgrain effects
Woodgrain foils add texture and depth for homes where plain uPVC would look too flat.
Smooth finish options
Architectural RAL colours
Dual-colour planning
Different internal and external finish choices may be used where the specification allows.
Hardware Finishes
Evolution colour and hardware choices affect price and lead time. Bowalker confirms the selected finish, glass, furniture and warranty details before the order is placed.
Performance and Features of Evolution Windows
Evolution performance is tied to timber-alternative construction, frame depth, glazing options and hardware. Evolution technical information lists an 82mm frame depth for Storm and a sleek 70mm depth for Flush, with 28mm double glazing as standard and triple glazing available.
Bowalker specifies these Evolution features around the property:
- Storm or Flush frame design: Storm gives a traditional overlapping casement appearance, while Flush gives a level sash line.
- Double or triple glazing: Storm 2 comes with 28mm double glazing as standard, and a triple-glazed unit may be specified where higher performance is wanted.
- Energy Performance: The Storm 2 window achieves a U-value of 1.3 and an A+ window energy rating as standard.
- Acoustic glass: Evolution lists acoustic glass options for homes where sound reduction matters.
- Multipoint locking with shootbolts: Evolution technical information lists multipoint locking with shootbolts across Storm and Flush windows.
- Timber-look detailing: Woodgrain finishes, joints, bars, beads and hardware help replicate older timber window character.
- Easy-clean and fire escape options: Evolution lists easy-clean and fire escape hinges, with child restrictors available where needed.
- Decorative glass choices: Low-energy glass, patterned glass, coloured glass and decorative leading may be specified.
Replacing Your Windows with Evolution
The signs that Evolution replacement windows may be worth considering include:
Rotten timber with old frames showing soft sections, cracked paint or repeated repair needs.
Draughts around older timber or uPVC frames.
Misted glazing from condensation trapped between old panes.
Poor style match from previous replacement windows that have flattened the character of a period or cottage-style home.
Failed hardware with loose hinges, stiff handles or locks that no longer catch correctly.
Noise or heat loss where rooms feel colder or louder than they should.
