Exterior blinds
Zetta 70 external horizontal blinds
Product gallery
Zetta 70 external horizontal blinds together with Zetta 90 external blinds are technologically the most developed blinds in the area of exterior shading technology, and are recommended for the shading family houses and administrative buildings. Lamellas with a width of 7cm are in the form of the letter “Z”. When closed, the lamellas create a self-contained area which ensures perfect shading and the rubber impressed along the whole lamella increases the thermo-regulation of the blinds. Aluminium guiding bars ensure the stability of the blind during windy conditions and function as a supporting element for securing the property against break-ins. The variability of the assembly, the modern technical design and perfect shading enables this external horizontal blind to create a unique shading element for all types of objects.

Assembly options
Basic types of assembly
These three types of assembly can be in two versions: cover box visible cover box incorporated into heat-insulation system or peripheral shell.
Specific assembly
- Self-bearing variant (fixation of the blind on guiding bars)
- Façade variant (round cassette; assembly on the façade)
- Assembly into Heluz lintel (built-in guiding bars)
- Assembly into Porotherm lintel (recommended for separate constructions)
- The self-supporting blind with packet of slats outside the head rail
It is necessary to consider assembly into a lintel in the plans for a family house.
