Maybe a transparent plastic foil that covers all the windows in winter could serve as double window. Question is how to fix it in place airtight. Maybe velcro fastener? Glue strips on the window around, and on the plastic sheet, then velcro it up. It could be taken down during warm seasons (some plastics also UV degradable, so that could give longevity).
Btw aren't you worried about you get doxxed?
