FWIW in Germany there's a requirement for buildings with automatic shutters to have one designated emergency exit window where the shutters can be operated manually. But fire-fighters shouldn't really have much of a problem if they carry an axe.
I didn't know the name either. Yeah, I'm spoiled by them in Spain (at least in my region, pretty much every residential house or building has them) and I typically sleep too little when I'm elsewhere due to lack of them. No other alternative I have seen comes even close when it comes to making a room really dark at night.
I just call someone to fix them, though. It's quite a dark art for those of us who suck at DIY.

It doesn't have German Rolladen though.
