Derby based Kensington Windows is a family run fabricator-installer that has always set its standards high, so when choosing supply partners, they only work with the best. The company has been working with Bison Frames for 9 years and has recently added the WarmCore bi-folding door to its portfolio from the high-end fabricator. “When we started buying from Bison Frames, we were just buying Vertical Sliders,” explains Steve McGinty, Operations Director of Kensington Windows. “We had used several different suppliers and experienced problems from all of them – we had quality issues, bits missing, and products just not being manufactured.
The aim behind the development of the Genesis Vertical Slider was simple: to create a window that could become a viable alternative to timber windows in Grade II listed and conservation area buildings. Two years on, that’s exactly what has happened. The Genesis Vertical Slider is regularly being accepted for use in heritage buildings where previously timber would have been the only option, including Grade II listed and conservation area properties. While it’s hardly surprising given the level of acceptance it has achieved amongst planning officers, the first thing that strikes you about the Genesis VS is just how authentic.
To take the best advantage of a growing market you need to have the right products in your portfolio. And when it comes to vertical sliders, the best product to have is the Genesis VS from Bison. Mark Tetley of Bison says, “The vertical slider market has grown 20% in recent years, so there are huge opportunities out there. Our Genesis VS offers everything the market is looking for and more.” The rapid growth in sales of the Genesis VS since it was launched in 2013 backs up Mark’s comments and demonstrates the market was waiting for a product with.
PVCU windows and Grade II listed buildings have historically been strangers. For planners and conservation officers, these buildings (and all too often, conservation areas too) have meant one thing only when it comes to windows: timber. Yet, in many cases, a modern timber window is inferior to its PVCU counterpart in terms of durability and thermal efficiency, not to mention more expensive. We wanted to develop a product that would give homeowners in listed and period buildings a genuine choice when they upgraded their windows. After much development and design work, the Genesis vertical slider was born. The Genesis VS.
We have just received listed building consent for our Grade II listed cottage to change the windows from wooden VS to UPVC VS. I thought it may be useful to explain the process we went through to help any interested parties wanting to do similar for a listed building or building in a conservation area. I have been involved in the PVC industry for a number of years so I had a slight advantage knowing the market and also how much UPVC VS window systems have improved in recent years. You do have to go through a full planning application.
