DIY Window Insulator Kit for 6'-8 x 19.5' Windows

Available in a variety of indoor and outdoor window sizes, 3M Window Insulator Kits keep cold drafts out and warm air in through heat shrink window film and Scotch Window Film Mounting Tape. With the clearest film that stays up all season long, these kits utilize Scotch tape technology to create an airtight seal.

The 3M indoor window insulator kit enables users to lower their heating bills during the winter and make their homes more energy-efficient. Part of 3M's line of energy-saving products, this kit includes window insulation film and a roll of double-sided mounting tape to establish an airtight seal. Stretching the film removes wrinkles for a transparent view, and this version of the kit allows for the insulation of one window measuring 6 feet 8 inches by 19 feet 5 inches.

Included with the kit is a 1/2-inch-by-27-7/10-yard roll of 3M window film mounting tape to keep the insulation in place all season long. This double-sided tape seals off cracks and crevices, creates an airtight seal, and establishes a strong bond between the surface, the tape, and the insulation film, as recommended in ENERGY STAR's "Seal and Insulate" guidelines. Featuring a convenient, ready-to-peel liner, the tape adheres easily to a variety of surfaces and stays intact upon removal.

Installing the window insulation is a simple and fast process. Users unfold the film, cut it to the width of the window (allowing an extra inch on all sides), firmly apply the mounting tape around the window frame, remove the paper liner, and then apply the film to the tape, starting at the top of the window. They then reposition and stretch the film to remove wrinkles, use a blow dryer to remove any remaining wrinkles, and finally trim any excess film.

Made in the United States and designed for indoor use only, this insulator kit can be used with aluminum, vinyl-clad, or painted or varnished wood molding, but it should not be applied to veneer paneling or Lauan mahogany molding. The film and tape should be removed from the window at the end of the season. The film measures 15 square yards, or 7 feet by 19.7 feet by 0.75 thousandths of an inch (H x W x D), and weighs 0.5 pounds.
