DORMA VISUR presents the door in perfect transparency. Rather than cluttering the clear outline of the leaf, the hardware components are all located in the surrounding structures. This absence of fittings means that the all-glass double-action door will match any room style, making the VISUR system a real boon to interior architecture.
100% transparent – 100% durable
Frameless from top to toe – that’s the DORMA VISUR’s claim to fame, making life easier for architects and specifiers alike. Because they can choose any material and any colour for the surrounding structures. The DORMA VISUR system simply remains a discrete presence, fitting in with every design idea and reflecting it to maximum advantage.
Transom-concealed door closer
In the case of DORMA VISUR all-glass double-action door, the closing function is performed invisibly by the transom-concealed DORMA RTS 85 EN3 door closer. This not only reliably returns the door to its zero position after each opening action, but also – thanks to special backcheck damping – protects the leaf from careless impact arising from excessive opening force.
Thanks to a hold-open feature included as standard, the door can also be retained at an opening angle of 90°. Clampable projections – leaf-integral ‘tongues’ – provide the mating connection for the concealed pivot fittings top and bottom.
Having successfully completed 500,000 operating cycles in its endurance test, there can be little doubt as to its outstanding quality of the VISUR system – a 100 % DORMA product in every respect.
