Blinds In Windows…

What are your thoughts on the “blinds-between-glass” style of window/door that has the micro Venetian or honeycomb blind in between the 2 panes of the double glazing?

I like them. They won’t get dusty. There is a Canadian study that shows the energy efficiency INCREASES with internal blinds. I am not sure about moving door panels, as the blinds get some movement too. But we had a sample that was lugged around everywhere even upside down and it always worked well… we will introduce these soon…
