Evolve vertical sliding windows offer endless variety to meet every customers needs…

The Evolve vertical sliding window has been designed to offer superior ventilation. Both top and bottom sashes can be partially opened, encouraging fresh air to enter the building at the bottom of the window while warm, stale air escapes at the top. It means that air is able to circulate constantly, keeping rooms fresh and comfortable.The window also features an overhead vent, allowing fresh air to flow all year round without compromising security.

As well as sliding up and down, both sashes in the window also tilt inwards. This innovative slide-and-tilt slide mechanism means that the outer glass panes can be cleaned safely and easily from within the building.

Security is a major concern for all homeowners, therefore our vertical slider has been specially designed to keep intruders at bay – featuring a tough aluminium anti-jemmy bar to prevent the sash from being levered open, as well as a choice of high-security locks.

The windows offer excellent fire safety too, as a large enough opening can be created and used as a means of escape, in line with the requirements of Building Regulations Part B (fire safety).

Modern solution

Evolve VS sash windows maintain the elegant proportions of traditional sash windows, whilst incorporating the very best in modern-day technology to deliver the low maintenance and high security of PVC-U without the problems associated with timber sash windows.

Quality assured Evolve VS sash windows feature tilting upper and lower sashes for ease of cleaning, low-line beads and glazing gaskets for improved sight lines and energy efficient glass for enhanced thermal performance.

From terraced housing to stately homes, Evolve VS sash windows enable old-style properties to retain their heritage, character and charm. A wide range of styles, colours and hardware options can be specified, whilst providing the benefits of modern-day technology.

Many buildings have been disfigured by inappropriate window replacements that have not maintained the original design aesthetics of the property. Once installed, new Evolve VS sash windows blend into their surroundings. Sculptured astragal glazing bars, decorative sash horns, two smoothly sliding sashes and a choice of quality operating hardware options all add to the traditional appeal of Evolve VS sash windows.

Evolve VS sash windows from Synseal are guaranteed for 10 years and manufactured using the highest quality materials under ISO9001 accredited quality management systems.

Safe and secure

Evolve VS PVC-U window frames are fully reinforced with aluminium and sliding sashes are reinforced with galvanised steel to resist deflection under extreme wind-loading conditions and carry the weight of the glass. In addition to strengthening the sashes, the galvanised steel reinforcement provides a strong, secure fixing for lifting handles, latches and other components.

High quality balances maintain the equilibrium of the sash window at any point of travel and robust locking devices ensure properties are secure. Evolve VS operating hardware is designed to give improved levels of strength and durability, safety and comfort to ensure that, once installed, the windows are built to last.

Energy efficiency

Incorporating brush seals around the openings for effective weatherproofing and draught exclusion, Evolve VS sash windows have an A window energy rating (WER) as standard and optional A+, B or C WER ratings can be specified.

Evolve VS windows are lead-free and choosing PVC-U over timber is an environmentally-friendly selection as the majority of end-of-life PVC-U windows can be recycled over and over again to produce new windows.

Double glazing units

Evolve VS sash windows are glazed with 24mm DG units as standard (4:16:4 pane and airgap configuration with Argon gas filling and Warm Edge spacer bar). Specification options include toughened or laminated Low-E glass for enhanced thermal performance. Diamond, square leaded, Georgian and Astragal bar options and obscured patterned glasses for added privacy are available.

Evolve VS windows are available in a variety of glazing bar configurations and shaped frame designs to suit the style of every property, including sizeable units for commercial buildings.

Equal sized top and bottom sashes (50/50 split) are standard, however windows can be manufactured with other split ratios to specification (minimum transom drop: 350mm).
