External Venetian Blind
The façade system meeting the sun before the glass. The guided slat stack is stable in wind, its control fully motorised.
Guide Styles
Three arrangements holding the slat stack in wind. Section and height make the choice.
| Guide | Operation | Note |
|---|---|---|
| Side Guide Rail | Slats slide inside an aluminium rail | The highest wind-resistance option |
| Cable Tension | Bottom bar runs on a tensioned steel cable | Slim façade line; medium wind class |
| Combined (Rail + Cable) | Both guides together on large sections | Stability on wide façades |
Being Outside the Façade
Six results of moving from an interior blind to a façade system.
- Cuts Heat Before the GlassThe solar load is met outside the façade; heat entering the interior falls noticeably.
- Flexible SlatC-form slats flex under wind load and return to form; the target is no permanent deformation.
- Step-Free LightTilt angle is preserved; light redirection is done even outside the façade.
- Motorised StandardLift and tilt run on the motor; the wind sensor is part of the system.
- Façade IntegrationThe cassette works visible or recessed into the cladding — decided in the project detail.
- Project ScaleOn foreign systems 4.5 m width and 16 m² area are recorded; the section is verified in the project.
Questions About the External Venetian Blind
How does it differ from an interior Venetian?
The external Venetian blind mounts to the outer face of the façade; it is designed with guided construction, flexible slats and wind resistance. An interior blind is not produced for these conditions.
How does it behave in wind?
The guide type sets the wind class. The rail-guided system gives the highest resistance; in strong wind the blind is brought to the gathered position — the sensor does this automatically.
Is a new building required?
No. Front-mounted cased units attach to an existing façade; in new projects the cassette can be recessed into the cladding and lost from the façade.
The interior counterpart of external shading is given in the aluminium series; on a façade opening outward the zip screen is the wind-secure alternative.
Let Us Discuss the Façade Project
Once the façade section, partition layout and wind zone are relayed, a guide type and cassette position are recommended.
