Why aren't Rolladens more popular in the US?

When my pops was in Germany during the 90's, their house and about every other house and small business building in Western Germany and Southern Holland had Rolladens. I love them - security, keeps house cool and dark (esp great for sleeping in the morning or napping). If/when I build my own place I'll put them in (there is a dealer here in Vegas). http://www.rolladenlv.com/testimonials/rolling-shutters-catterton.php For those who haven't seen them, they're a rolling shutter that is similar to siding material, that come out from the side of the house and interlock over the windows - closed, they look like vinyl siding.

They would be perfect for every house in the American Southeast - hurricane territory... basically in 30 seconds every window in your house is a metal wall. But you never see them. Why? Ever since I first went to Germany I thought for sure that would be a 9 figure industry if it caught on in the USA, but 15 years later it still hasn't.

What's up? Maybe some builders can chime in.

 

I dunno. I think they're also a great alternative to having metal bars over your windows (in any inner city). A little more asthetically pleasing than black iron IMO.
