External venetian blinds can direct daylight very precisely. If additional dim-out is required, the slat geometry of the external venetian blinds is the decisive factor. WAREMA offers special dim-out slats for this.

External venetian blinds with dim-out slats reduce light gaps and make rooms noticeably darker. Decisive for this are the closing of the slats, sealing, and appropriate guidance.

Do you want to know which dim-out slat suits your windows and how the solution is installed in your home? Use the WAREMA specialist dealer search and get advice on execution, operation, and details on site.

These slats are designed for dim-out and reduce the incidence of light more than standard slats.

Why does it get darker?

  • Sealing strip at the slat edge reduces light gaps.
  • Optimised closing of the slats ensures less stray light.

Suitable for

  • Bedrooms and children's rooms
  • Rooms for TV and home office
  • Areas with a desire for more privacy at dusk

This slat is designed for a particularly high dim-out effect.

Why is it particularly effective?

The sealing strip and closing of the slats are designed for maximum dim-out.

In combination with suitable finishing details, the incidence of light is further reduced.

External venetian blinds with dim-out slats make rooms significantly darker. Completely light-proof like in a photo studio is not the constructive goal for a FIX slat system. Small residual light gaps may remain depending on the installation situation.

Dim-out with external venetian blinds works when the slats close cleanly in the closed position and light gaps are minimised.

The lateral guidance also influences the result. The better the unit is planned for the window and facade, the less residual light remains.

The end rail and sealing help reduce stray light. This is especially noticeable at dusk and with street lighting.

For dim-out, a motorised operation of the external venetian blinds is particularly useful:

  • Finely adjust the slat angle
  • Repeatable positions for "Day", "Dusk", "Sleep"
  • Optionally combinable with control functions
