Can you call them ask for the manufacturer? They should be very glad to help.

I guess I need to remind everyone including myself: they aren't rich. They will take any money flowing into their pocket. Imaging you are an wall street investor...

I think they were field fabricated. There is probably a similar perforated sheet stock available, but the profile of the shutters isn't a typical one, so I think they were then pressed, shipped to the site, had the parts to attach them applied, and then put on. I don't think it was an off the shelf system as they seem to come up with their own (for instance the Herrnstrasse Work/Housing building also in Munich that no longer has the shading system functioning).

You could try here:

perforated sheet

check out zahner - not sure if it is who they used for that project. i think they did the facade screens at the de young

There is also a Swiss company called Hawa who manufactures similar shutter systems

Surely there is a third option for the pictured example, namely custom fabricated off-site ? Any fabricator would give a better price for doing the work in his own facility as opposed to the tailgate of a truck -- no ?

Funf Hofe has been refinished at least three times I believe.

So, I'd imagine they're nothing special in terms of construction.

ive seen em up close and they dont work too well - so they are 'frozen'.. ie they dont move
