Genesis uPVC Windows



The Genesis Vertical Slider Sash Window is a great alternative to timber and is fast becoming approved by many Local Planning Authorities as being a very good alternative to timber. Also the cost to replace your windows if you are in a Conservation area, and you are allowed Genesis, is far less than replacing with timber and the Guarantees are far better too.. they feature a unique timber look alike joint, unlike a traditional window. It is not welded but mechanically works like a timber window. It is a unique window that really does hit the spot when it comes to traditional appearance.

The unique joint design to both sash and outer frame replicates a traditionally- made timber window for a truly authentic appearance, setting your windows apart from the rest. Combined with period hardware and a complete range of heritage finishes, the Genesis Vertical Slider pushes the boundaries of modern PVC-U sliding sash windows. Performance, style and elegance are all at the forefront with this period-feel window.


Genesis recreates the beautiful styling of a traditional timber sliding sash window - with its authentically jointed frame and sash it replicates the windows of yesteryear that are found in period cottages and older properties.



With its elegant styling and precision design, the Genesis vertical sliding sash will enhance any modern home as well as a traditional property. Designed for modern living, Genesis combines cutting-edge technology with the traditional character of a box sash window. Precision-engineered for smooth, simple operation, Genesis effortlessly complements your modern lifestyle.

There are many benefits from choosing a Bison Genesis VS, some of these include:

1 Developed to satisfy the aesthetic requirements of Conservation areas and listed buildings. The Bison Genesis Vertical Slider is manufactured using traditional jointing methods to give a truly authentic, alternative to expensive timber windows with the added benefit of proven modern PVC energy saving and low maintenance technology.

2 Structural joints which allow for traditional dry glazing and easy replacement of broken, scratched or failed glass units just like any other PVC window on the market today.

3 No need for expensive, time consuming, labour intensive glass bonding glazing methods, which is not only impractical but would make changing a glass unit almost impossible without changing the sash or the entire frame.

4 The Genesis VS unique jointing system, because it's weld free, allows for outer frames to be flat packed for ease of transport or access. You can easily and cost effectively replace a style or jamb of a sash ON SITE should it get damaged during or after installation.

5 New high security Acorn cam locks and sash buttons, authentic, period hardware.

6 Genesis VS is only available from BISON. Why settle for second best when you can have a Genesis VS.

7 New external Ovolo weather bar for enhanced weather performance, security and aesthetic appearance.

8 Fully milled Decorative Astragal Georgian Bar.

9 Run through sash horns and deep bottom sash rail as standard.
