Our range of aluminium bifold doors are fully compliant with Doc L of the Building Regulations.
Folding doors for internal use can be specified with a low threshold or a flush track so the two floor levels remain constant. Our Visofold aluminium folding door has a 30mm low threshold which can be sunk into the floor.
Traffic Door Option
Many styles can be specified with a traffic door which provide a normal day-to-day door leaf, allowing easy access to the garden without opening the whole bi-folding door up.
High Security Locking System
Our folding sliding doors are fitted with the latest high security locking. On styles supplied with a traffic door, lever handles operate a high security hook-bolt locking system and a profile key cylinder allowing access from both inside and outside. Bi-fold doors supplied without a traffic door do not have external access and can only be opened from the inside by operating the shoot bolt locking system, using the handles fitted to the meeting stiles of the door
