Introducing the Cortizo 4700 In line sliding patio door with patented Korniche Technology.
Appealing specifically to buyers looking to maximise views through their chosen door solution, the Cortizo 4700 sliding patio door has become the go-to option in the UK. Affordable, reliable, and available in multiple configurations, it also remains incredibly easy to install.
Its slim central interlock and sleek frame provide minimal sightlines, creating a clean and modern aesthetic that complements any home.
Korniche engineers have taken the standard 4700 door design and enhanced it with a range of key performance improvements. Korniche technologies help speed up and simplify installation, deliver slimmer sightlines with better vent integration, and introduce a host of additional security features alongside stylish new hardware options.
All of this is achieved while retaining the core qualities that have made the Cortizo 4700 a market leader. To complete the package, every door also benefits from Korniche quality aftercare and a gold-plated 10-year end-user warranty as standard.
The unique patented SpeedBead, a special ingredient allowing our sliding patio doors to be glazed in seconds, along with a neat groove design allowing the seals to be hidden within the frame.
PAS 24:2022 Security
Our Cortizo 4700 Sliding Doors come rigorously tested to keep homes fully protected.
Certified to the advanced PAS 24:2022 standard, their strong durable aluminium frames come with enhanced security from our high strength shoot-bolts.
The lockable shootbolt handles have an innovative anti-back drive feature engineered into it. Even unlocked, a forced entry attempt can’t rotate the handle to open the door.
Simply Better Together
Expertly engineered, the proven Cortizo 4700 sliding doors are the market leader for good reason. Exuding the same quality in fuction as they do in design, they are an even better proposition when packed with Korniche Technologies that enhance security, aesthetics and ease of installation.
Cortizo Core
Crafted from premium thermally broken aluminium, our sliding doors combine clean, modern design with outstanding performance. A slim 47mm interlock creates a strong, elegant central sightline, while precision-engineered running gear ensures smooth, effortless operation for years to come.
Deep polyamide thermal breaks and high-performance seals help minimise heat loss and protect against draughts and water ingress — keeping your home warm, comfortable, and weatherproof all year round.
Enhanced with Korniche Innovations
Designed to complement the sleek look of the system, our in-house shoot-bolt handles are paired with refined pull handles for a premium finish. PAS 24 compliant locking and anti-backdrive technology provide enhanced security and peace of mind, while Document Q compliance can be achieved with laminated glass.
Integrated trickle vents are discreetly positioned within the top frame, maintaining clean sightlines and reducing the need for bulky extensions around the plaster line.
Installation is faster and simpler thanks to our patented SpeedBead system, allowing glazing in seconds. Pre-fitted slimline seals help maximise glass area, natural light, and uninterrupted views. The bead can be removed and replaced easily without damaging key components.
