I am thinking that air (if it is still) is a very good insulator.
So why aren't we putting the window shutter far away from the window?
It would have more air between the window and the shutter and the Question: it would cause better insulation?
Or above a few centimeters thickness, the airflow would start anyways by itself and it would just only backfire?
because on that link I don't understand what are the letters mentioned in the formulas.
can you pls update that answer with more details on what is what, ex.: what is "A" or "ΔT"
or would my theory work? to make the distance bigger between the windows and the shutter
many thanks :)
