The basis of the self-supporting blinds are guide rails, on which the entire weight of the armour lies. The main representative of this special design of exterior blinds is the VIVA self-supporting blind. All types and sizes of slats can be used for this self-supporting blind, except for Cetta 50. An insect mesh can also be integrated into them.
For the VIVA blind, the upper profile of the blind, including the entire package of slats, is placed in an pre-assembled box, which has an angular design. Its box can be made in two variants – under-plaster or recognized. The under-plaster variant means that the box is "hidden" under facade and when the blind is fully retracted into the box, this blind is not visible at all. This variant of design must be taken into account already during the implementation of the construction project. In the under-plaster version, the VIVA blind box can be provided with 10 mm thick hardened polystyrene from the front and back at the same time. The box is visible for the recognized variant.
