Bi-Fold Door Configurations

Our bi-folding door range have a wide variety of options when it comes to sizes and opening configurations – available up to 7 panes wide.
Our door pane numbering works like this:

  • The first number shows the number of doors in total
    within the frame.
  • The second number shows the majority of doors folding back to either left or right.
  • The third number shows the balance of doors opening in the opposite direction.

So, a 4-3-1 bi-folding door would be four panes wide, with three doors folding back to one side of the frame, and a single opening door on the other.

Please see below for examples of our configurations.
