Aluminium bi fold doors, or bi folding doors, have been growing in popularity over the last decade and have now become recognised as a fundamental feature.

Many styles can be specified with a traffic door which provides a normal day to day door leaf, allowing easy access to the garden without opening the whole bi-folding door up. 

The doors are fitted with the latest high-security locking system.  On styles with a traffic door, lever handles operate a high security hook bolt locking system and profile key cylinder allowing access from both inside and outside. 

Bi-folds supplied without the traffic door do not have external access and can only be opened from inside by operating the shoot -bolt system, using the handles fitted to the meeting styles of the door.
