Add close-fitting thermal curtains or blinds
Thermal curtains and blinds cut draughts and mean cold glass won’t make people uncomfortable. The cheapest option is tightly woven or foam-backed lined curtains that fit well. Better options use thermal interlinings or trap air movement by adding a box or pelmet over the window, or are blinds that attach directly to the window frame. Some home sewers can make cheap but effective curtains and blinds. If you put a door curtain on a fire exit, make sure you leave it open when people are in.
