External venetian blinds
Control of the blade’s tilt can be managed in a way that light may still flow into the room in a sufficient amount even with the sun and heat protection still staying intact. The extension of these systems with automated control via the use of a wind-sun-controller further increases comfort using the external venetian blinds. The blinds simply close up should the preset insolation settings be reached.
Weatherproof systems – through wind and rain
To protect the year-round exposed external sun protection systems, they are all fitted with guiding ropes or guiding tracks to ensure stability against the weather. However they still need to be packed up if winds reach a certain force. At what point that is the case depends on the position and type of the product used. To automate that process a wind-controller can be installed.
External blinds are often installed with a screen to hide the underlying mechanics and the package when it is in a parked position.
