Aluminium bi-folding doors: How they work and why material matters

---

22.08.2025

Aluminium bi-folding doors are becoming increasingly popular in UK businesses and buildings thanks to their space-saving functionality and clean, modern design. 

What are aluminium folding doors and how do they work?

Unlike other automatic doors, an aluminium folding door opens by folding into tucked away sections, saving space as it doesn’t require a swinging path. 

Automatic aluminium folding doors are powered by electricity, using motion detectors for contactless entrance to diminish the need for manual operation, which is particularly beneficial for high foot traffic environments and businesses where hygiene is imperative.  

Like any automatic door, the aluminium folding door can be a single or double door with or without windows. 

Why aluminium? 

The most common material choices for folding doors are wood and aluminium. Businesses choose wood for its rustic look, natural thermal efficiency and environmentally friendly material. 

But if you’re looking for a sleeker, more contemporary style, then aluminium is best suited for you. 

Aluminium also comes with some significant advantages that wood does not, such as:

• Improved durability – even in harsh weather conditions
• Low maintenance 
• Significantly longer life span 
• Higher level of security
• Energy efficient 

Aluminium bi-folding doors are popular in the UK because, unlike wood, they do not warp or change in harsh weather conditions, and are therefore a better long-term investment for businesses.
