Key Features
Smoother
Korniche bi-folding doors exude the same quality in their function as they do in design, with an exclusive roller system that delivers an effortlessly smooth glide every time.
Slimmer
With a clean, consistent and slim design, our bi-folding doors superbly reflect the care with which they were made, with frames that can be powder coated in vivid colours on either side.
Safer
The frames come with enhanced security that includes a 3 Star Yale locking barrel, high strength shoot-bolts and multi-point locking systems.
Warmer
With high precision materials and equally high manufacturing tolerances, our bi-folding doors feature polyamide thermal breaks to keep heat in and the cold out.
Security
With PAS24 as standard on laminated glass options and the YALE 3 star locking barrel, The Korniche Bi-folding doors are second to none when it comes to strength and durability.
Multi-point locks with combination of hooks, sliding roller and deadbolts.
Korniche Shoot-Bolt Handle features a unique anti-back drive that ensures the door cannot be forced open if the shoot bolt is left unlocked. The handle is disengaged with only a 110-degree turn of the handle with a high gear ratio gearbox.
The Shoot bolt handle also makes it impossible to leave the key in and avoid crushing and damaging the frame with the key.
Slave door sashes are fitted with a hidden ‘flip-flop’ locking lever providing top and bottom shoot bolt engagement.
Quality
Exclusive to the Korniche bi-folding door system – Stainless steel rail and roller wheels with articulated wheel axle arrangement allowing door loading to be equally distributed along the rails for the fastest smoothest glide and operation.
