About Twinfix


Based in Warrington, Twinfix are proud to be a high quality, safety focused, British manufacturer and installer of roof glazing and canopies.

Established in the late 1980’s, Twinfix was the first company in Europe to develop a range of glazing bars and fixing accessories specifically designed for installing polycarbonate. A family business, owned and led by Graham Kench, the company is now managed by Graham’s daughters Vicky Evans and Sarah Kench, together with fellow directors Dan Smith and Paul Greenfield. Growing from its original roots as polycarbonate and glazing bar suppliers, today Twinfix offers a full range of glazing products from the original glazing bar products to the non-fragile Multi-Link-Panel which is often incorporated in to a wide range of canopies and shelters. Working across many sectors, from rail to education and retail, Twinfix offers a full service from initial enquiry and advice on projects, to design, manufacture and install.

Our brilliant design team has over 30 years’ experience in glazing bar development and roof glazing innovation, producing many unique products from our Georgian wired effect polycarbonate (a solid polycarbonate that looks just like Georgian wired glass), to our thermally broken Multi-Link-Panel.

We have a new 3D printer that allows us to continually develop our product, testing new bar shapes and sections.

Manufacture and Fabricate

We are proud to be a British manufacturer. From our factory in Warrington we produce bespoke canopies and glazing systems. Our cutting edge facilities include multiple CNC saws, CNC profile machining, a large capacity notching saw, an automatic vertical panel saw, a box section roller, a 4mtr 100 tonne pressbrake and guillotine and 6 modern aluminium TIG and MIG welding machines. We invest in our machines to help us to safely and efficiently manufacture our product.

All of our work is in aluminium which is an excellent material, known for its light weight and high quality look and feel. In order to ensure a swift and accurate installation on site we also dry assemble all of our canopies in our warehouse to ensure that they fit together on site.

All our canopy structures are UKCA marked.
