Explanation of Rouladens
It's a nifty idea. Basically, you build a box above the window....on the interior usually....and you roll up or down this rouladen.
Initially....decades ago....these were all wooden in nature, and you moved them by hand.
Over the last decade, they've gone to light aluminum, electric motors, and push-button devices to move them up or down.
The advantages? Well....first, it secures the house when you are out. If they are in the down position....it's pretty hard for a guy to break in. Second, in bad weather.....like hail storms......you put them down and protect the windows. Third....which fits appropriately for this time of you.....you use them to lessen the heat in the house.
The cooling effect is rather unique. You have the windows open all night and around 10AM.....you close the windows and bring the rouladen down. The rouladen reflects the heat, and doesn't allow the glass windows to draw heat into the house. While the outside temp at 4PM is around 94 degrees.....your inside temp is likely 85. It's at least comfortable.....not hot. Then around 8PM.....you raise the rouladen, open the windows and the even temperature lessens the heat in the house and brings everything back to a starting point.
The negative about the rouladens? If they break or get mangled up.....you just about need to call some specialized repair guy. There's maybe one or two things that a regular guy can do, and beyond that.....it's hopeless.
Why they never caught on in the US? I'm not sure. I always thought they were a fairly good idea.
