Every year I put plastic film over my windows for the winter. Invariably the film fails. The cheap ass double stick tape fails. The cats claws inadvertently destroy the film. Or pressure from the door opening and such makes them pop off. Dollar general sells these cheap ass shower curtains ($1.29 weirdly). And the most amazingly strong double sided "Craft" tape (Also $1.29). Cut the curtains up to fit your windows. Tape them up. Works like a champ.
