Insulating drafty windows for winter, this XL window shrink film kit seals a clear plastic film over a window to trap an insulating air barrier that cuts drafts and heat loss through the glass. Double-sided tape holds the film around the window frame, and a pass with a hair dryer shrinks the film drum-tight and wrinkle-free for a nearly invisible insulating pane that stops cold drafts and condensation all winter, then peels off clean in spring. The XL kit covers large or multiple windows. It is an economical way to insulate old or leaky windows without replacing them.
