Why Choose Bi-Folding Doors?

Bifold doors can transform the aesthetic appeal and functionality of your home entrance. They’re a fantastic way to open up your living space to a wider vantage point, making it feel larger and brighter.

When you install bifold doors, they essentially replace a wide section of your wall with glass, letting you see through clearly, without compromising on insulation or thermal efficiency. These can be made using many different materials, however, we find that aluminium works supremely well for this application.

Why you Should Install Aluminium Bifolds?

Bifold doors aren’t reserved for high-end builds and luxury designs — they can be integrated into pretty much any style of installation, in any type of home.

Wondering what makes aluminium bifold doors the perfect choice for your home entrance? Here’s everything you need to know.


The major advantage with these doors is the material they’re made from. Unlike wood or UPVc, aluminium doesn’t get affected by the weather at all — it doesn’t crack, expand or lose strength, no matter how humid, or dry the climate is.

Energy Efficiency

Did you know that over 25% of the heat from your home escapes through your windows and doors? The same applies for air conditioning. Our bifold doors have a reliable “A” rating for energy efficiency, ensuring great thermal insulation and minimal leakage.


Our installation team can install doors from as little as 1500mm wide using two door leafs, and we can go right up to 7 metres wide, using up to 7 door leafs. We provide a wide variety of options including handle types and finishes. We can also install bifold doors which turn 90 degrees to expose the entire corner of your home!


Embracing the full aspect view of the outside world is the real advantage of installing bifold doors. Our entire product range offers unbeatable weatherproofing solutions to make sure the elements stay outside when they’re not welcome.


Safety is paramount when it comes to buying new doors. We manufacture heavy duty bifold doors that are PAS 24 compliant, with state of the art locking mechanisms.
