The right coverings can reduce heat loss through windows, especially at night.
Options
- Cellular (honeycomb) shades trap air in their cells
- Thermal or lined curtains that seal close to the wall
- Curtains that reach the floor or sill and use a cornice or valance on top
- Interior storm panels for drafty windows
- Close them at dusk in winter
