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.
