UKO Group is proud to announce a major enhancement to our aluminium product portfolio with the full transition to high‑performance Cortizo systems across our window and door portfolio. This strategic move marks a significant step forward for us, delivering enhanced performance, refined aesthetics, and a smoother, more installer-friendly experience while maintaining the trusted look and feel customers expect.
At the heart of the transition is a new generation of aluminium bifold and patio door systems, alongside the ever-popular window range. These new systems bring cutting-edge design and engineering together, offering a sleek, contemporary finish without compromising on strength or usability.
We are the first to launch this brand-new Cortizo bifold system in the UK. The bifold system offers even slimmer sightlines, now 100mm, reduced from 107mm, for a cleaner, more contemporary look. The system also brings back the popular pre‑gasketed clip‑in bead, maintaining a trusted aesthetic while improving performance and simplifying installation.
The updated aluminium window collection is now available in Flush, Standard and Heritage styles, ensuring suitability for a wide range of architectural preferences. When paired with energy‑efficient glazing, the windows can achieve U‑values as low as 1.0 W/(m²K) which supports excellent thermal efficiency.
Expanding the range further, we have also introduced the new Cortizo 4900 sliding patio system. Featuring slim 35mm interlocks and a fully beaded design, it enables faster installations while achieving U-values from 1.2 W/(m²K). The result is a product that perfectly balances style, performance, and energy efficiency for today’s homeowners.
Colin McCabe, Group Manufacturing Lead, UKO Group said: “Cortizo allows us to deliver higher performance and a better‑looking product without complicating installation or increasing costs. It’s exactly the kind of step forward we want to bring to our customers.”
A spokesperson from Cortizo said: “We’re proud to work with UKO Group as they bring the benefits of Cortizo technology to their customers. The move reflects a shared dedication to providing products that combine design, efficiency and ease of installation. It’s a partnership built on delivering real value to the end user.”
This transition marks a significant step forward for us, reinforcing our commitment to innovation, customer satisfaction and long‑term value. These elevated products will be available across the UKO Group brands and full technical specifications are available on request. Contact us to find out more!
