When we lived at Kalamazoo Michigan, our house had a basement bedroom that my son used. It was cold and damp. We solved the cold problem by making removable window plugs from 2-inch thick foam board.
The windows were recessed into the cement wall of the basement. The opening was tapered just a little. By carving a plug for the window opening out of two-inch thick insulation board, we stopped the cold draft. The foam board pushed into place sealed the window opening and insulated it too.
Yes, we lost the benefit of the little bit of light that might have come in through the windows. The savings in heat and comfort by far out weighted the loss of light. My son was in his bat cave stage at the time and did not want light any way.
As I remember it, the windows were covered with posters of Star Wars movies, hiding the foam plugs from view.
When spring arrived, the foam plugs were easy to remove.
Try it you’ll like it.
