ᐅ What type of blinds or external Venetian blinds are these? Do you know the manufacturer? (in a Regnauer house)

Hello everyone,

We recently visited the display home exhibition in Munich Poing and saw these blinds / external venetian blinds on a Regnauer house.
Unfortunately, the house was not open, and so far the manufacturer has not replied to my email.
We saw blinds there that looked very sturdy and wind-resistant. The slats were made of fairly thick material.
Does anyone here know the manufacturer of these blinds?

Thanks for your help
