My comment about the shades with the tapes, rings and mylar was a result of some research my sister and I did about 20 or more years ago when solar houses were all the rage here in New Mexico. Some people were making Roman shades they called Warm Windows using quilted fabric with a layer of Mylar sandwiched in the middle. The idea was that in summer the mylar would reflect heat out and in winter it would reflect the warmth back into the room. I'm not sure if they attached somehow to the window frame but it seems to me that if they had a slightly wider width than the window it would fit snugly and keep the cold or heat out.I don't know what the R factor was but it was high. Is it really possible to get R factor equal to that of a papercrete wall which would be 30+? Long commute? You have a job? That couldn't be possible with all that you contribute to this group. If I ever know where you live I guess I forgot. Refesh my memory please?

Ideally I'd want to have a shade system with an R-factor that
approaches the R-factor of the wall. No small challenge. This will
probably require more than one shade, but this could be an
advantage. The shade closest to the window could be a light passing
shade while the inside-most shade would be light blocking and more
decorative.
Gee, if I moved to New Mexico do you think I'd find any neighbors
with papercrete experience? Gorgeous country, but the commute would
be a doozie!

use quilted fabric (even insert a layer of mylar in the middle if you
want) and attach the tapes to the back and the hardware along the top
of the window opening. It was a long time ago but I would think they
are still available. And I know of 2 lovely tracts of land for sale
in my neighborhood in Northern New Mexico. There's a lot of stuff on
the market here.

only place the insulation will be compromised by crushing is at the
fold. Rings placed on the face at the location of the desired folds
will allow a cord to go from top to bottom for lifting the shade.
