Where and how to use folding doors: Internally & externally 

---

22.08.2025

Folding doors are versatile entry solutions for commercial and business spaces. From dividing open-plan interiors to opening up your building to the outdoors, they offer flexibility, space-saving and style. 

But where do they work best? And how can the use of external folding doors differ from indoor folding doors? 

Why are folding doors so popular?

Both external and internal bi-folding doors save space as they don’t require swing room to operate, and they’re also incredibly durable and low maintenance. Perfect for spaces with high foot traffic or withstanding the UK’s harsh weather conditions.

Uses for internal bi-fold doors 

Office partitioning 

As open-plan offices rise in popularity, the need for office partitioning grows. Internal folding doors can divide office areas without taking up too much space to operate. 

Healthcare access 

In healthcare, hygiene and accessibility are crucial. Folding doors provide hands-free movement between rooms and don’t obstruct wheelchair users. 

Education buildings

Schools and universities have many facilities like libraries and lecture halls on campus, which folding doors allow smooth access without compromising on space or safety for their students. 

Uses for external folding doors 

Retail entrances 

Automatic folding doors are a useful entry solution for retail businesses with narrow shopfronts, where sliding doors are not feasible. 

Emergency healthcare facilities 

When space is limited but foot traffic is high, the folding doors enable fast and safe operation in emergencies.

Transport hubs 

Hotel, airport and train station entrances deal with a constant stream of people with lots of luggage. Entryways must be efficient and leave enough space for the users.
