You might consider having the insulating shade fan fold instead of roll. It will make deployment and (?) undeployment easier and the 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.

It is a simple roll down shade design where a rod or tube acts as a
spool. When open, the spool is at the top of the window with the
insulating and decorative fabric rolled around it. The top edge of
the fabric is permanantly attached to the top casing. When closed,
the entire spool decends unfurling the fabric as it goes. The spool
rolls along two sloped tracks on each side of the window that are
about 1/4" per foot out of plumb. The sloped ramps on each side
allow the fabric and spool to rest against them and eliminate air
convections. Depending upon the stiffness of the fabric and the
width of the window, dowels or other stiffeners are sewn into the
fabric horizontally at vertical intervals. Gravity holds it all in
place.
Keep in mind that the window wells I anticipate are deep, around 2
feet. There is plenty of room to hold this.
Of course, first things first. I don't have my land to build on.
I'm not really too worried about window treatments. I need to buy my
view before I look to frame it.
