This is a heat-shrink window film kit: a 17.5 ft roll of clear 0.75 mil plastic plus Scotch double-sided mounting tape. You tape the film to the window frame, then shrink it tight with a hair dryer to seal out drafts. The thin film is the clearest 3M makes, so it keeps the view while cutting drafts, condensation and frost. It suits renters and homeowners with old single-pane windows who want a cheap seasonal fix rather than new windows or storm panels.
