Korniche Aluminium Bi-folding Doors

The Ultimate Installer Advantage: The Korniche Speedbead

The Korniche Bi-folding Door system is designed to perfection, combining robust, high-security functionality with breathtaking architectural elegance. Engineered to maximise natural daylight while minimising sightlines, these premium doors deliver a flawless, ultra-smooth glide every single time.

For trade installers, it is a game-changer. Delivered with precision-machined components and innovative glazing tech, a Korniche bi-fold slashes time on-site, completely eliminating the typical headaches of traditional door installations.

Fast and easy to install

Time is money on-site. The biggest revolution in the Korniche bi-fold design is the patented Speedbead glazing system.

No More Wrestling Gaskets: Traditional bi-folds require installers to spend hours manually wedging and rolling wedge gaskets around the glass panels.
Fast Clip-In Application: The Speedbead replaces traditional gaskets entirely. Once the glass unit is set, the rigid bead simply clips cleanly into place using a soft mallet.
Precision Fit First Time: It achieves a perfectly secure, uniform, and weatherproof seal across the entire frame in a fraction of the time, with no adjustments required.

The Easiest, Smohest Glide

Equipped with an exclusive stainless steel rail and an articulated wheel axle arrangement, the weight of the door panels is distributed completely equally along the tracks. Utilising sealed stainless steel roller bearings, the doors slide open effortlessly with a simple touch.

Market-Leading Heat Retention

Engineered with extra-wide polyamide thermal breaks and industry-leading Q-Lon main outer frame seals, these doors comfortably comply with modern Document L building regulations. When specified with advanced high-performance glazing, they prevent cold bridging to keep spaces exceptionally well insulated.
Thermal Performance: U-values down to 1.6 W/m²K as standard (or lower depending on specified glass centre-pane).

Smart Shoot-Bolt Security

The bespoke Korniche shoot-bolt handle is beautifully styled and engineered with built-in protection: its unique mechanical design makes it physically impossible to leave the key in the lock, entirely avoiding frame crushing or accidental damage when folding panels back.

Integrated Trickle Vents

Say goodbye to ugly frame extenders and added hardware costs. Trickle vents can be neatly integrated directly into the head of the outer frame profile, maintaining the slim, sleek, contemporary sightlines of the door set.
