Internal Crittall-Style Doors: The Ultimate Room Divider
Broken-plan living for the modern home. We supply and install slim-framed internal glass partitions in Windsor, Ascot, Sunningdale and across all 32 London boroughs.
The Crittall-Style Aesthetic: Heritage Design for the Modern Home
The “Crittall-style” look — slim black frames and multiple glass panes — originates from mid-19th-century steel window designs. It has seen a massive resurgence because it balances industrial grit with architectural elegance. The Korniche Internal Door system replicates this heritage look using high-grade aluminium, creating a striking focal point in both traditional and contemporary interiors.
Technical Precision: The 34mm Advantage
The Korniche system features some of the narrowest sightlines on the market — mullions, transoms, and frame profiles as slim as 34mm. By utilising 6063 T-6 aluminium, the system maintains high structural integrity even with these slim profiles.
Ultra-Slim Sightlines
34mm profiles maximise glass and minimise frame, unlike bulkier timber or uPVC doors.
SpeedBead Technology
Glass panels secure into the frame in seconds, with no visible fixings and easy serviceability.
Magnetic Locking
Smooth, light closing action with no mechanical “click”, for a premium feel.
Acoustic Upgrades
6.8mm acoustic laminate glass available for enhanced sound reduction.
Practical Zoning: Managing Light and Noise
Home offices: A Korniche glass partition lets you stay visually connected to the rest of the house while blocking out noise — ideal for the rise of remote work in Ascot and Sunningdale.
Kitchen-diners: Contain cooking smells and noise while keeping the view into the dining space. Doors fold back to provide a wide, unobstructed thoroughfare for entertaining.

Ideal for standard doorways or narrow home office entries.
French Doors
For wider openings between living and dining rooms, up to 2000mm.
Fixed Screens
Standalone glass walls to create “zones” in large open-plan extensions.

Frequently asked questions
How long does installation take?
Typically, a standard single door or French door set can be installed within a few hours. Larger partitions with multiple fixed screens may take a full day, thanks to the SpeedBead system.
Can I have these doors in colours other than black?
While Matt Black is the most popular choice, other RAL colours can be specified to match your existing aluminium windows.
Do the doors have a threshold on the floor?
The Korniche system can be installed with a low-profile threshold, or in certain configurations designed to minimise trip hazards.
