Cortizo 4700 Sliding Doors 4 Sash

Are you tired of dark, cramped rooms that feel cut off from the outdoors?

The Cortizo 4700 sliding doors effortlessly blend indoor and outdoor living, bathing your home in natural light and enhancing your space with a serene, open atmosphere.

With their ultra-slim frames, minimalist design, and smooth gliding mechanism, these doors bring a touch of contemporary elegance to any room. The slim central interlock and precision-engineered profiles ensure a sleek, uninterrupted view, making them a stunning focal point in modern homes.

The Cortizo 4700 Sliding Door is a premium aluminium sliding patio door system designed to maximise natural light, uninterrupted views, and modern aesthetics. Featuring slim 47mm sightlines and expansive glazed panels, it creates bright, open living spaces while maintaining exceptional strength, security, and thermal efficiency. Enhanced with exclusive Korniche innovations, the system delivers a refined balance of style, performance, and ease of installation.

Manufactured using thermally broken aluminium profiles, the Cortizo 4700 offers outstanding weather resistance and energy performance, with double and triple glazing options available. Wide polyamide thermal breaks, high-performance seals, and advanced glazing configurations help reduce heat loss, improve comfort, and meet modern building regulations. The system is also PAS 24:2022 security certified, featuring enhanced shootbolt locking and anti-backdrive technology for added peace of mind.

Korniche SpeedBead technology significantly simplifies installation by allowing glazing in seconds without traditional wedge gaskets, reducing fitting time while maintaining a clean, high-end finish. Integrated trickle vents are discreetly concealed within the frame to preserve minimal sightlines and a streamlined appearance.

Available in a wide range of RAL and bespoke finishes, the Cortizo 4700 can be configured in 2, 3, 4, or 6 sash layouts with double or triple track options. With sash sizes up to 2500mm wide and frame widths up to 6400mm, it is ideal for large openings, contemporary extensions, and luxury residential projects. Smooth-running stainless steel hardware and precision-engineered rollers ensure effortless long-term operation, even with oversized glass panels.
