Dim-out external venetian blinds are a specialised form of external venetian blinds . Their external venetian blind slat types , edge sealing and guidance are designed to reduce light gaps and lower the incidence of light. They do not create complete blackout; residual light may remain depending on the installation detail.
Dim-out external venetian blinds use shaped slats and system details that close more closely than standard slats. The result depends on slat geometry, sealing strips, lateral guidance, end-rail detail and installation tolerances.
A WAREMA specialised retailer can assess the window and select a compatible system, drive and control solution.
Dim-out slats 73, 90 and 93 are designed to reduce incident light more than standard slats. The final result depends on the complete blind and installation detail.
How the slats reduce light
- edge sealing helps reduce light gaps
- the closing geometry limits stray light between slats
- compatible guidance and end-rail details support the dim-out effect
Typical applications
- bedrooms and children’s rooms
- media rooms and home offices
- rooms where stronger privacy is required at dusk
The Zetra dim-out slat 80 Z is designed for a high dim-out effect. Its Z-shaped closing geometry and edge sealing reduce light gaps between adjacent slats.
The result also depends on guidance, dimensions, installation tolerances and the lower closure. Small residual light gaps may remain.
Dim-out external venetian blinds can make rooms significantly darker, but the system is not completely light-proof. Residual light can remain at lateral guides, between slats or at the end rail, depending on the installation.
The slats must close in a coordinated position, while edge sealing reduces gaps between adjacent slats.
Lateral guidance, fixing and installation tolerances influence how much residual light enters at the sides of the blind.
The end rail and lower closure determine how much stray light can enter beneath the blind. The available detail depends on the selected system.
Motorised operation can make defined blind and slat positions easier to reproduce when compatible controls are specified.
- adjust the blind height and slat angle
- store repeatable positions where the control system supports them
- combine operation with compatible time or sensor functions
