Aluminium Bi-Fold Doors

Let The Light Flood In...

Explore Our Aluminium Bi-Folding Doors

Flood any room with natural light and, in just a couple of seconds, open up for extra space and the feel of a cool summer breeze. The addition of a bi-fold door can completely transform a living space – their flexible nature mean they can be fully opened, partially opened, or totally closed depending on the space available and, naturally, on what the weather’s like. Versatile and aesthetically pleasing, our bi-fold doors are the perfect replacement for existing sliding patio or French doors to flood any room with natural light.

Innovative and Visually StunningBi-Folding Doors

It’s not just about beauty. The aluminium bi-fold doors utilise industry leading technology that gives you – and your home – the absolute cutting edge in looks, weathering, and security. Our bi-fold doors are the full package – excellence both inside and out.

All of our bi-fold doors are designed with slim contemporary lines and hidden gearing. Sophisticated hardware has never looked so sleek and stylish.

High Security PerformanceTotal Peace of Mind

Nothing matters more to a homeowner than security. Using the latest technology, the aluminium bi-fold doors ensure that you and your family’s safety is never in question.

All of our doors use shootbolt locking features, with 3 hook locking and latch for all master doors. The security doesn’t compromise the bi-fold doors’ sleek design though – all the locking systems are enclosed within the aluminium casing, maintaining the pleasant aesthetic and keeping the mechanism away from interference.
