FAQs
Q: What makes this sliding door different from standard Cortizo 4700 doors?
A: The Cortizo 4700 by Korniche integrates patented Korniche technologies, including slimmer sightlines, SpeedBead clip-in glazing, enhanced thermal performance, advanced security features, and sleek proprietary hardware—all exclusive enhancements developed by Korniche’s engineering team.
Q: Is this door secure enough for my home?
A: Absolutely. It is certified to PAS 24:2022, featuring Korniche’s shoot-bolt locking system with anti-backdrive technology. This means even when unlocked, the handle cannot be rotated by force from the outside.
Q: How energy efficient is the door?
A: With a U-value as low as 1.3 W/m²K (with triple glazing), and full Document L compliance, this door keeps your home warm in the winter and cool in the summer, reducing energy bills.
Q: Can I customise the colour of my sliding door?
A: Yes! You can choose from three popular stock colours or over 150 bespoke RAL finishes, including dual-colour options for interior/exterior contrast. Bespoke colours may extend lead time by approx. 5 weeks.
Q: What’s the installation process like?
A: Installation is quick and straightforward thanks to Korniche’s SpeedBead system, pre-fitted seals, and pre-assembled panels. Full guides and crane-assisted oversized glass delivery are available.
Q: Do the doors support integrated blinds or trickle vents?
A: Yes. Trickle vents are discreetly fitted through the head of the frame for a clean look, and integrated blinds are available for most glazing configurations.
Q: What configurations are possible?
A: The door can be fabricated with double or triple tracks, allowing for wide openings and custom setups. You also have options for flush thresholds and minimal step-overs.
