What Are Aluminium Concertina Doors?
Also known as concertina aluminium doors, concertina bi fold doors, or just concertina doors, these are a type of bifolding door made up of multiple glass panels connected by slimline aluminium frames and discreet hinges.
The panels open in a concertina-like zig-zag fashion, folding and stacking neatly to one or both sides of the frame.
Sleek, Functional, and Versatile
When closed, these doors look like a sleek wall of glass, offering wide, uninterrupted views of your garden or outdoor space. When opened, they completely transform a room by removing the barrier between inside and out—perfect for creating that sought-after open-plan lifestyle.

Built for Performance and Convenience
Each door leaf slides and folds along a track, with options to configure the number of panels, the opening direction (inward or outward), and even include a “traffic door”—a single hinged door for everyday access without opening the whole system. The use of aluminium means the frames can remain incredibly slim while still supporting large panes of double- or even triple-glazing.
Perfect for Modern Living
These doors are ideal for homeowners who want to maximise light, create a connection to the outdoors, and add a striking architectural feature to their home, whether it’s a modern extension or a period property with a contemporary twist.
Why Are They So Popular?
Perfect for Open-Plan Living
Aluminium concertina doors have quickly become one of the go-to choices for homeowners, architects, and developers alike—and it’s not hard to see why.
They tick all the boxes: form, function, and flair.
First off, they perfectly suit the UK’s growing love affair with open-plan living. With just a gentle push, these doors fold away to open up an entire wall, allowing you to seamlessly blend your home and garden.
A Seamless Indoor-Outdoor Connection
Whether it’s hosting a barbecue, enjoying a quiet cuppa with the sunrise, or simply keeping an eye on the kids as they play outside, concertina doors bring flexibility to everyday life.
Let There Be Light
These doors are designed to flood interiors with natural light—even when closed—thanks to their slimline aluminium frames and expansive glazing. This not only boosts the look and feel of your space but also helps reduce the need for artificial lighting, contributing to better energy efficiency.
High-End Style Meets Practical Performance
Whether you’re going ultra-modern or updating a period property with a contemporary edge, aluminium concertina doors offer a minimalist, high-end look that elevates any project.
Finally, they’re practical. From space-saving designs to high-performance insulation and security features, these doors meet the everyday demands of busy family life while still looking effortlessly stylish.

Design & Aesthetic Appeal
Concertina doors are celebrated for their clean lines and modern elegance. Aluminium, being naturally slim yet strong, allows for large glass panes with ultra-slim sightlines.
Want a traditional-meets-modern finish? Anthracite grey frames in a matte finish are particularly popular for industrial-style homes and extensions.
Prefer something warmer? Go for a dual colour finish—grey outside, white inside—to balance external curb appeal with a cosy interior vibe.
Complement these doors with matching aluminium roof lanterns, window frames, or internal glazing screens for a consistent, curated feel throughout your space.
Key Benefits & Features
- Max Light Inflow: Minimal framing, maximum glazing = brighter interiors.
- Thermal Efficiency: Look for thermally broken frames and low-E glass to keep your home warm.
- Security First: Multi-point locks, shoot bolts and PAS 24 certification as standard.
- Weather Resistance: Seals and drainage systems built for the UK climate.
- Smooth Operation: Gliding tracks, sealed bearings and anti-lift rollers for effortless use.
- Configurable: 1-7 sashes, open in or out, with traffic door for everyday use.
Brands like Korniche and Smart Visofold deliver class-leading performance across these areas, offering some of the most reliable concertina aluminium doors on the market today.
Installation & Maintenance
Installation is quicker and simpler than many expect, especially with systems like Korniche that come pre-assembled and ready to glaze. Here’s a quick overview of what the process might look like:
- Measure your aperture accurately.
- Choose your door configuration, colour, and threshold type.
- Our team delivers your doors pre-assembled (or in kit form for DIYers).
- Fit the frame, insert the panels, glaze the units.
- Secure everything in place with final adjustments.
Maintenance? Easy. Thanks to the powder-coated aluminium frames and advanced weather seals, a simple wipe down is all that’s needed to keep them looking fresh. No warping, no rusting, no repainting. Keep the tracks clear of debris and check handles annually for smooth operation.
How to Choose the Right Style for Your Home
Here are some key things to consider:
- Opening Configuration: 3-3-0? 4-1-3? More panels = wider opening. Odd numbers often allow a central traffic door.
- Threshold Type: Choose between rebated thresholds for better weather protection or low thresholds for step-free access.
- Ventilation Needs: Consider integrated trickle vents for passive airflow—ideal for new builds.
- Colours: Over 150 RAL shades available, including dual colour options.
