Traveling through Europe, seeing many different construction methods, I try to take an objective look at why things are done a certain way.
One of the most positive things that I see done in Europe compared to the US is that a lot of their (almost all in some regions) window blinds are built into the window unit and are on the outside.
The first benefit and a much sleeker inside that isn't cluttered by blinds and then there has to be a substantial insulating factor.
Is there any reason why this isn't implemented in the US? And do you know of any reports/studies done on the comparative energy savings of outside blinds?
Note that this is a bit pricey because it has the electric guidance for the blinds. Most have metal chains and the preferred is usually the chain since it is a PITA to fix the electric ones plus the extra hookup. I would expect to pay 200-300 Euros for a window this size normally.
