Zetta 90 external horizontal blinds

Zetta 90 exterior shading is technologically the most advantageous external window blind in the area of exterior shading technology recommended for shading family houses and administrative buildings. Lamellas with a width of 9 cm are in the form of the letter “Z”. When closed, the lamellas create a self-contained area which ensures perfect shading; the rubber impressed along the whole lamella increases the thermo-regulation of the blinds. Compared with Zetta 70 blinds, Zetta 90 external window blinds 90 are recommended for shading large areas because the lamellas give a visually larger impression. 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.

The exterior shading technology creates an optimal environment in terms of lighting and thermal conditions and is a key part of the construction in terms of energy savings. In the traditional concept, exterior shading fulfils the shading and security function, whereas in the non-traditional concept, it is an architectonic element of administrative buildings and adorns family houses.

Advantages and benefits

  • high level of shading
  • thermoregulation and protective effect
  • decrease in the level of outside noise
  • lower profile from the extruded aluminium
  • electric control option
  • decrease in the noise from the blinds (impressed rubber)
  • guaranteed area of up to 24 m2.

References

Manner of control

  • manually – by handle
  • electrically – by remote control unit or switch

Guaranteed dimensions

  • minimum width: 600 mm
  • maximum width: 4,000 mm (for handle control) / 6,000* mm (for motor control)
  • maximum height: 4,000 mm
  • maximum area: 8 m2 (for handle control) / 24 m2 (for motor control)

* Note: The wider the blind, the lower its wind resistance class – see Wind resistance, further down the page. 

Non-standard dimensions are not produced.
