Korniche engineers have taken the standard form of the 4700 door and improved elements of the design with key performance enhancements.

Korniche technologies speed up and simplify installation, provide slimmer sightlines with better vent integration, add a host of security features and add some sleek new hardware options. All whilst still retaining the key features that make it a market leader.

We also add Korniche quality after care and a gold plated 10 year end user warranty as standard.

reliable security

Our in-house locking shoot-bolt handles perfectly compliment the slider and are paired with all new colour matched pull handles. PAS 24 is now standard issue thanks to the fully lockable shoot-bolt gearbox, preventing operation from the outside even when unlocked thanks to anti-backdrive technology. Document Q compliance is achieved when specified with laminated glass.

A Market Leading Slider
with Korniche Technology

Where would BMW be without the M division? Mercedes without AMG?… Yes, the core products are proven market leaders and do exactly what you need them to, but those famous engineering partnerships just offer something a little better, more desirable. And that’s exactly what a Korniche Technology partnership is all about.

Korniche trickle vents at the top of the sliding doors

A signature feature of Korniche, trickle vents are fitted through the top of the door frame meaning a super slim extension piece is all that’s required for the plaster line. This design is a more aesthetically pleasing solution for your home.

thermally broken

Keeping control of the temperature in your home is vital, especially during the winter. Our aluminium frame parts have deep polyamide thermal breaks which keep outer and inner parts thermally isolated from each other minimising heat transfer. Bespoke designed seals complete the picture protecting the system against air and water ingress. Our sliding doors are designed to keep heat in and weather out.
