Energy-efficient folding door FFT FLEX Green-Dorma Kaba

Maximum clear opening widths in tight spaces
The wide folding door requires very small space when folded open – to the side, to the front and to the rear:
With a height of 2.5m FFT FLEX Green offers 2 options for opening doorsets:
Bi-parting opening doorset: up to 2.4 m
Unilateral opening doorset: up to 1.2 m
The folding door is suitable for both external doors and internal doors in narrow passageways as well as barrier-free access points in public buildings.
Efficient thermal separation
The thermal separation with low thermal transmittance values enables a sustainable and reliable system to support the planning of an energy efficient building. We support our customers with the computation of their specific thermal transmittance value.
Enhanced wind load resistance
The innovative operating system of FFT FLEX Green detects wind loads and compensates accordingly to guarantee a smooth opening and closing behavior.
More performance, less wear
The intelligent operator transmits its power without toothed belts for significant gains in dynamic response and silent efficiency. The doorset thus opens and closes particularly quickly, yet also quietly and with minimum wear.
For emergency exits and escape routes
Dormakaba’s proven DualDrive technology ensures emergency in any situation. A reliable opening and closing of the door is guaranteed by the fact that the system self-monitors on a continuous basis. In case of power failure an integrated battery pack provides for the reliable operation
