Frost King Indoor Window Shrink Insulation Kit, 42-in x 62-in

The Frost King Indoor Window Shrink Insulation Kit provides a quick and easy solution for insulating your home’s windows, reducing drafts, and improving energy efficiency. This kit includes clear shrink film that fits windows up to 42 inches by 62 inches. Once applied, the film tightens when exposed to heat from a hair dryer, creating a wrinkle-free, clear barrier that helps keep warm air in and cold air out. Perfect for use during the colder months, this insulation kit is ideal for single-pane windows and can help lower your heating bills by preventing heat loss.
