Zetra slat is an 80 Z-shaped profile for WAREMA external venetian blinds. Within the available external venetian blind slat types , its linear geometry is designed for cubic façades, adjustable daylight control and enhanced dim-out. The permissible wind load and available system configurations depend on dimensions, guidance and installation.
The Zetra slat combines a defined Z-shaped profile with a sealing element and concave reflection surfaces. Depending on the blind configuration, these features support:
- a linear façade appearance
- adjustable daylight and glare control
- enhanced dim-out compared with standard light-guiding slats
- coordination with selected roller shutter profiles and colour finishes
The Zetra slat 80 Z received the Red Dot Design Award 2022.
The linear profile can be coordinated with modern window and façade grids. Selected Zetra slat colours are also available for the A 37 roller shutter profile, allowing external venetian blinds and roller shutters to be visually aligned. Availability depends on product and market.
The 80 Z Zetra slat is designed to reduce light gaps when closed. It can be specified for living and sleeping areas where stronger dim-out is required, but it does not create complete blackout.
In the referenced WAREMA comparison, the closed 80 Z slat achieved up to 25 per cent greater dim-out than the predecessor system. Actual residual light depends on the complete blind, lateral guidance, end-rail detail, installation tolerances and ambient light.
When open, the concave reflection surfaces support controlled daylight distribution and view out. Four matt surface colours are coordinated with the A 37 roller shutter profile.
The Zetra slat provides enhanced dim-out and adjustable light control in compatible external venetian blind systems. The selected slat angle determines daylight, glare, view out and privacy. Product-specific operating and installation limits apply.
The linear profile is intended for façades with clearly defined horizontal lines.
The permissible wind load for a Zetra slat system depends on blind width and height, guidance, fixing and installation position. Use the current technical documentation rather than a general wind-speed value.
The Zetra slat is available in defined standard and matt colours. Product, system and market availability must be checked during specification.
Compare available powder-coated colours for guide rails, guide profiles, cover panels, boxes and frames. Product and market availability vary.
Use the coordinated collection to compare available colours for external venetian blinds, roller shutters and visible aluminium components.
