Bison Frames is known across the industry as a trade fabricator of high-end PVC-U vertical sliders. However, 2018 sees the launch of the company’s expanded Genesis Collection and WarmCore range, which represent a complete suite of high-end products. Mark Tetley, Director of Bison explains: “We’re very well known and respected for our sash windows, because we have the expertise and skillset in-house to continuously improve our offering. We constantly design-in new features and customer benefits, to make our existing products better and better. However, 2018 sees this philosophy expand into a whole suite of products, to ensure our customers can.
