This is the most unusual of the Griesser rolling shutters, because strictly speaking it’s not a rolling shutter – it’s a stackable shutter, as it’s stacked instead of rolled up. The Rolpac^® system has a unique benefit – it doesn’t take up much space in the header. This opens up a wealth of new possibilities for reconstructions or renovations in narrow installation situations, as well as in modern architecture, where glass and an unrestricted view outside play a key role. Rolpac^® provides other benefits too, for example generous slat spacing, which guarantees better room ventilation and light levels than conventional rolling shutters; it also features an integrated safety locking device, developed in accordance with the proven Griesser security concept. The safety sensing edge, which is available as an option, automatically stops the rolling shutter lowering as soon as the motor detects an obstacle, protecting it from damage.
