Well, those are windows with glass in. I don’t think there are many places which have windowless houses, and since windows leak more heat than walls in winter, you typically have smaller windows in very cold places.
Blinds on the inside do help, because they trap a layer of hot air next to the windows rather than letting it further into the house. It’s better to keep it all outside, of course, but it’s better than nothing.
Modern windows can give oldskool walls a run for their money in terms of insulation. Although a proper designed and insulated wall can do better. It’s not just the glass, but also the gasses used in between the panes and special coatings applied.
