With the 3M outdoor window insulator kit, you can lower your heating bills during the winter and make your home 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 create an airtight seal. Stretching the film removes wrinkles for a transparent view. This version of the 3M outdoor window insulator kit enables you to insulate two 3-foot-by-5-foot windows.

Keep the Heat In and the Cold Out Made by 3M, this outdoor window insulator kit contains window insulation film along with Scotch Window Film Tape to keep cold drafts out and warm air in. As a result, you can reduce your heating costs during the winter. The film shrinks tightly around your window for a transparent, wrinkle-free fit and is made to reduce condensation and prevent frost build-up.

Double-Sided Mounting Tape for a Secure Seal Included with this kit is a 1/2-inch-by-13-4/5-yard roll of 3M window film mounting tape to keep your 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.

Simple, Fast Installation Installing the window insulation is easy. You simply unfold the film and cut it to the width of the window, allowing an extra inch on all sides. Next, you firmly apply the mounting tape around the window frame and remove the paper liner. Then you apply the film to the tape, starting at the top of the window, and reposition and stretch the film to remove wrinkles. Finally, you press the film firmly to the tape and trim any excess film.

Made in the United States, and designed for outdoor use only, this insulator kit can be used with aluminum, painted wood, or vinyl-clad surfaces, but it should not be applied to masonry or to roughly sawn or unpainted wood. The film and tape should be removed from the window at the end of the season. The film measures 4 square yards, or 5.16 feet by 7 feet by 0.75 thousandths of an inch H x W x D, and weighs 0.13 pounds.
