Keep the Heat In and the Cold Out
Made by 3M, this indoor patio door insulator kit contains insulation film along with Scotch 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 tight around your door frame 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 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 door insulation is easy. You simply unfold the film and cut it to the width of the door frame, allowing an extra inch on all sides. Next, you firmly apply the mounting tape around the frame and remove the paper liner. Then you apply the film to the tape, starting at the top of the door, and reposition and stretch the film to remove wrinkles. Finally, 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 should not be applied to veneer paneling or Lauan mahogany molding. The film and tape should be removed from the door at the end of the season. The film measures 7 square yards, or 7 feet by 9.3 feet by 0.75 thousandths of an inch (H x W x D), and weighs 0.24 pounds.

What's in the Box
Insulation film and one roll of mounting tape.
