What Are Cor 4700 Sliding Doors?

Slim Frames, Bigger Views

The Cor 4700 is a high-performance aluminium sliding door system from Cortizo, one of Europe's largest and most respected aluminium systems companies. It sits in the sweet spot of the Cortizo range: modern, slim sightlines and strong performance, at a more accessible price than ultra-slim bonded systems like the Cor Vision.

Built for Modern Living

The system takes its name from its slim 47mm central interlock. That is the vertical bar where two glass panels meet. Keeping it this narrow means more glass, more daylight, and a cleaner view of your garden. Add a fully thermally broken aluminium frame, large panel capacity, and smooth precision rollers.

Why South London Homeowners Choose the Cor 4700

We fit a lot of sliding doors across South London, and the Cor 4700 stands out for its excellent value, combining premium looks with strong modern performance at a mid-range price. Slim sightlines maximise glass, daylight and garden views, making smaller spaces feel more open. Its deep polyamide thermal break and double or triple glazing provide impressive energy efficiency, with U-values as low as 1.1 W/m²K. For added peace of mind, it offers PAS 24 security, a multi-point locking system, and durable aluminium construction that requires minimal maintenance.

FAQ

Frequently Asked Questions

How much do Cor 4700 sliding doors cost? 

Prices depend on size, number of panels, glazing, and finish. As a mid-range Cortizo system, the Cor 4700 typically costs noticeably less than ultra-slim bonded sliders while offering similar modern looks. Contact 4Moon Windows for a free, tailored quote based on your exact opening.

What is the difference between the Cor 4700 and Cor Vision sliding doors? 

The Cor Vision is Cortizo’s ultra-slim, structurally bonded system with a 20mm interlock. The Cor 4700 uses a slightly wider 47mm interlock but is simpler to manufacture and install, which makes it more affordable. Both offer excellent thermal performance, security, and large glass panels. 

Are Cor 4700 sliding doors energy efficient? 

Yes. The system uses a deep polyamide thermal break and accepts glazing up to 36mm thick. With high-specification triple glazing, U-values can reach as low as 1.1 W/m²K, comfortably exceeding UK Building Regulations and helping to cut heating costs.

How big can Cor 4700 sliding doors be? 

Individual panels can reach up to 2500mm wide and 3000mm high, with sash weights of up to 300kg. Multi-panel configurations on triple tracks can span openings of more than 6 metres, making the system ideal for large extensions and open-plan spaces.

Are Cor 4700 sliding doors secure? 

Yes. The system is tested to PAS 24 security standards and comes with a multi-point locking system as standard. Optional laminated glass and anti-lift features provide additional protection, making these doors a safe choice for family homes.
