Beaded slats are the classic slat geometry for external venetian blinds. They combine view out, wind stability, and flexible light guidance, and are therefore used particularly often.

With external venetian blinds you control daylight very precisely. The slats are infinitely variable in tilt and reduce glare, heat input and insights. The fact that a slat geometry works so well in everyday life depends heavily on stability and closing behaviour.

Beaded slats are made exactly for this "reliable standard".

  • Stable in weather and use: suitable if the unit is to run robustly and permanently.
  • Good balance between view out and visual privacy: You keep the view outside without compromising privacy.
  • Flexible daylight instead of "fully open or fully closed": slat angle finely regulates light and glare.
  • Effective thermal protection at the window: External sun shading systems stop sun rays before they heat up the glass.

Beaded slats have folded and reshaped edges on both longitudinal sides. These edges stiffen the slat, make it dimensionally stable and create the classic slightly curved external venetian blind appearance.

A beaded slat is not a flat aluminium strip, but a profiled strip with folded, reinforced edges. This makes it robust and durable.

This is how the shape affects:

  • More stability: The folded edges stiffen the slat. It remains shape-stable in everyday use.
  • Clean slat finish: The defined edge shape ensures the slat closes more evenly.
  • Typical appearance: Beaded slats appear slightly curved and are the "classic" look for external venetian blinds.

Beaded slats are a good choice if you…

  • want a "classic" external venetian blind with proven appearance and function.
  • need to plan for more wind stability in locations exposed to wind.
  • are looking for a versatile solution that works in many facade and window situations.

Beaded slats are often used in wind-stable external venetian blinds in locations exposed to wind. Which version suits you also depends on guidance and installation situation.

Beaded slats are primarily designed for light guidance. If you want targeted dim-out, special dim-out slats are the more suitable approach.

In addition to the classic beaded slats, flat slats and dim-out slats are among the various slat shapes for external venetian blinds from WAREMA.
