3M Indoor Window Insulation



    Product Description

    Available in numerous 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. 3M window kits have the clearest film and stay up all season long with Scotch tape technology. Scotch double sided tape holds firmly between films and surfaces.


    With the 3M indoor window insulator kit, you’ll be able to lower your heating bills all over 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 indoor window insulator kit enables you to insulate five 3-foot-by-5-foot windows.

    Keep the Heat In and the Cold Out
    Made by 3M, this indoor window insulator kit contains window insulation film together with Scotch Window Film Tape to keep cold drafts out and warm air in. Because of this, you’ll be able to reduce your heating costs all over the winter. The film shrinks tight 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 Protected Seal
    Included with this kit is a 1/2-inch-by-27-7/10-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 numerous 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. In the end, you use a blow dryer to remove any remaining wrinkles, then 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 will have to not be applied to veneer paneling or Lauan mahogany molding. The film and tape will have to be removed from the window at the end of the season. The film measures 10 square yards, or 5.16 feet by 17.5 feet by 0.75 thousandths of an inch (H x W x D), and weighs 0.33 pounds.
