What is meant by slat?

Lamella (from the Latin “lamella” = thin disc) is used in our context for a long rod that is arranged repeatedly several times.

For example, in a roller shutter curtain, the individual profile bars are called slat. Similarly, in the case of a sliding shutter, the profiles are repeated in height. These profiles cause the typical shadow.

By cleverly arranging the slats, attractive aesthetic and architectural effects can be achieved on the one hand, and on the other hand, desired technical and functional aspects can be utilised.

For example, in the case of a sliding shutter, the slats can be arranged so that they block direct sunlight, which usually shines on the blind from above, but allow indirect light, i.e. reflections of the surroundings, to pass through in the gaps. This creates a strong shading effect behind the sunshade but still allows a certain amount of light to enter.

In roller shutters, the lamellar arrangement enables the curtain, i.e. the roller shutter curtain, to be rolled up and down, resulting in a space-saving structure when closed.

Slats also often help to save material and thus weight when replacing a functionally equivalent but more solid because of full-surface or full-volume construction.
