Ah damn. You can try traditional vinyl backed blockout curtains but they can be a bit stinky, especially right after being washed.
If you don’t have curtain hooks a tension rod will work but it depends on the width of the window. It’s expensive and tougher to find tension rods over a meter and I had hooks so cheap blockouts over the blinds it is.
I more used the tension rods to suspend blankets (with a quickly sewn fold-over casing) in doorways as curtains, in order to heat or cool a smaller space while still letting the cat get to her bowls and litterbox.
Be warned though - leaving one room unheated/cooler in winter can contribute to condensation and mould issues.

Definitely weatherstrip the doors too if you can
