External venetian blind slat types differ in shape, width, stiffness, stack height and closing behaviour. These features affect daylight control, view out, dim-out performance, wind resistance and façade appearance. Compare the slat options available for external venetian blinds .
WAREMA offers beaded, flat and dim-out slats in different widths and compatible product systems. The appropriate slat type depends on the required function, window dimensions, guidance, wind loads, stack height and façade design.
Beaded slats have profiled edges that increase stiffness. They provide adjustable daylight control and are available in defined widths and systems. The permitted dimensions and wind loads depend on the complete blind configuration.
Dim-out slats use a closing geometry and edge sealing to reduce light gaps. The Zetra slat has a linear Z-shaped profile. Dim-out performance depends on the complete system and installation detail and does not mean complete blackout.
Flat slats have a slender profile and can provide a compact slat stack. They support adjustable daylight and view out. Available widths, guidance types and permissible dimensions depend on the selected system.
The WAREMA Colour World provides compatible powder-coated finishes for visible aluminium components. Availability depends on the selected product and market.
The coordinated collection supports colour matching between external venetian blinds, roller shutters and visible aluminium components.
external venetian blinds use tiltable slats to regulate daylight, glare and privacy. Beaded, flat and dim-out geometries provide different stack heights, closing behaviour and wind resistance.
Because external venetian blinds are positioned outside the glazing, they can reduce the solar radiation reaching the glass when correctly planned and operated. The actual effect depends on glazing, orientation, dimensions, slat position and use.
