This is a riddle that has baffled many mathematicians, philosophers, scientists and lecturers.
The Oxford dictionary tells us that the word ‘bi’ is defined as two / having two. In theory this means that the definition of a bi-folding door is a door set that does not have three, four, five, six, seven or eight folding panels-only two!
However, historically speaking, in the bi-fold door industry, a bi-folding door is an internal timber door that has two panels. If the bi-fold door has more than two panels then surely it is not a bi-fold door. In theory this is then a sliding, folding door or a concertina door if you prefer.
Unlike other bi-fold door specialists, the people at Arbor Window Systems Ltd do know the difference between a bi-fold door and a sliding folding door.
Arbor Window Systems can provide you with door sets that will open up your house; doors that will give you more space and light; doors that can be opened with ease and make entering and exiting your house much easier.

So, when is a bi-fold door not a bi-fold door? When it’s a sliding folding door from Arbor.
