Visofold 6000
The Visofold 6000 slide and fold door offers extremely slim profiles which are perfectly suited to residential properties where narrow sight lines and maximum glass areas are required
Low threshold custom design option for unimpeded easy access tailored to your individual specification, which ensure the perfect finish at floor level or rebated thresholds that improve weather resistance.
Visofold 6000’s flexibility also makes it suitable for commercial projects.
Where large opening apertures are required, the system offers maximum light and space to give unimpeded views.
This highly-versatile, easy-to-operate system is the perfect option for even the largest project. Capable of opening up an entire wall, yet presenting a contemporary, elegant glazed façade when closed.
The system features a choice of internally or externally folding sashes, which when open, sit flush to the frame. Sashes are hung from a floating mullion and slide on a recessed bottom roller and top guide. This allows for ultra-slim profiles, smooth operation and robust security.

Premium Security Fitted As Standard With Patented Active Cam Technology
The clever locking system of the Avocet ABS® diamond grade cylinder knows when it has been snap attacked and fires into action to create a robust barrier to entry. The patented Active Cam TechnologyTM is hidden deep within a solid Molybdenum cam which is 20% stronger than steel, and delivers ultimate resistance against a lock snapping attack and snap/twist manipulation. All of the snap technology is focused on the outside part of the lock only. This makes sure that maximum strength is given to the inner part of the lock – the part that has the job of securing your door.
