The blind is therefore ideally suited for bedrooms, presentation rooms and anywhere where the incidence of light needs to be reduced on demand. A bead in the front edge of the slat also reduces the incidence of light and prevents rattling noises. The exceptionally robust slats make this external venetian blind highly durable. On high buildings or in wind-exposed locations, we recommend our additionally reinforced wind-stable external venetian blinds. These external venetian blinds are available with dim-out slats as well. Of course, our dim-out venetian blinds are also available with standard equipment options such as daylight transport blinds.
