Roller shutters or venetian blinds are opened and closed at the push of a button or even fully auomatically - resulting insignificantly less effort for the end user. But convenience is also combined with other practical benefits: Using a timer to close roller shutters at dusk can significantly cut energy loss - particularly the energy lost through windows.

Criminal investigations also reveal a further practical advantage. When lowered, roller shutters provide better burglar protection because intruders see them as an additional obstacle.

In future, bus technology will doubtlessly assume increasing significance. Efficient and, at the same time, user-friendly building management is possible by creating a complete, software-driven network of all devices and control systems capable of being connected to the mains supply. Maintenance-free, durable, easy to install and user-friendly.
