Like Silly Putty that has been stretched out into a long rope, rope caulk may be pulled apart and jammed into wide gaps and holes in your windows. Apply rope caulk along the margins within the window cases. Do the exterior of the windows as well if you live in a ground-floor flat for added insulation.

Insulation made from window film— Window film is a sizable piece of shrink-wrapped plastic attached using double-sided adhesive tape. This is a barrier between the pane and the cool exterior air to keep the heat inside. To start, measure the size of your window frame and cut the sheet to fit. Use the double-sided adhesive to attach it to the outside of your window pane. To improve the seal quality, shrink the film using a hair dryer’s heat.

Window caulking is a common and affordable solution for winter draughts. First, remove all loose caulking from the window frame with a putty knife. Then, either use a caulk gun to fix any gaps or cracks or insert sealant strips along the internal wall frame. This will stop cold air from entering via the wall and internal sill. However, avoiding caulking around a window opening in an emergency is best.
