Perfecting the vertical slider

Mark Tetley, director of Bison Frames takes a look at the importance of the mechanically jointed concept and the impact that the Genesis Vertical Sliding Window has had over the last four years in the window industry.

In the beginning the Genesis VS fully mechanical concept was conceived purely to meet the needs of the largely untouched heritage market, previously dominated by timber windows. The success since it was first introduced has given Bison’s sales a boost and shown the industry that the Genesis concept and attention to detail has become a benchmark.

One of the biggest changes in the VS market is the growing acceptance of PVCU for use in conservation areas and in some cases Grade II listed properties. The level of acceptance Genesis has achieved amongst planning officers is hardly surprising because the first thing that strikes you is just how authentic it looks – an area where the Genesis VS has blazed a trail as the customer’s first choice, a true alternative to timber with rapidly growing sales up and down the country – a real testament to the Genesis VS fully mechanical concept.

The vertical slider has now become a core part of most installers’ portfolios – an essential product that no longer just appeals to the heritage market but has been attracting more and more attention in the new build, self-build and general retail markets for use in modern and contemporary homes. This is in part down to recent developments in the industry as more and more products are following in the footsteps of the Genesis VS mechanically jointed concept which was launched at the first FIT Show in 2013, and is still at the pinnacle of authenticity.

Genesis is still leading the way and there are four key reasons for this. The first is the Genesis concept – the use of traditional timber jointing methods on the frame and sash. The second is a full range of contemporary colours, heritage colours and woodgrain foil finishes to the meet the growing needs of both homeowners and architects. The third is the fact that PVCU outperforms timber hands down when it comes to energy efficiency. And finally ‘It’s the attention to detail that makes the difference’.

The Genesis VS also offers run through sash horns and a deep bottom sash rail as standard or without for a more contemporary feel. It also has a wide range of design possibilities with the optional fully milled Astragal Georgian bar, ovalo or putty line to give either a traditional or contemporary feel to any property plus high security hardware in a full range of colours to suit everyone.

The Genesis Vertical Slider is very much a modern window. It’s easy to fit and maintain, it has a tilt open facility for easy cleaning, and is capable of achieving window energy ratings (WER) of A, B and C.  

There is little doubt that the sliding sash is considered a classic for a reason: it’s a good-looking window that adds instant kerb appeal to any traditional or contemporary property. When you combine the looks of a traditional timber sliding sash with the practical benefits of PVCU, you have an unbeatable combination.
