Size of the windows for exterior blinds

Since I am the blinds man here... Which blind? 80mm slat hemmed? The package height depends on the slat width and whether it is a flat slat or a hemmed slat.

THANK YOU! We would choose the one that takes up the least space in order to have the largest possible windows! What is your recommendation for this? THANK YOU!

60/80 flat slat, however not stable in wind/storm

If necessary, take a look at the 90s Z lamella, it is flat and stable.

Thank you for the tips! But how high is the [Jalousie-Kasten] now? And: How high can the windows be with a room height of 2.75 m, with a usual floor construction?

THANK YOU!

Depending on which [Lamellen Format] you choose. Between 15 and 25 cm
