With its modern form, s_onro combines blind and roller shutter functions in fascinating fashion. At a pitch of 20 degrees and above the aluminium blind shields the interior from direct incoming sunlight.The unique construction enables transparent privacy screening and sunshade and also lets the room be blacked out. The amount of incoming light can be individually determined by opening and closing the blind. With its high level of transparency, s_onro ensures sufficient light inside and the ability to see outside.

Once the angle of elevation of the sun exceeds 20 degress s-onro ® does not allow any direct sunlight into the rooms. If darkness is required then the lamellars are closed up. If there is a desire to maintain contact to the outside world, then the s-onro ® can be raised individually to in exactly the level of light that is desired.
