With the 3M indoor 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 indoor window insulator kit enables you to insulate two 3-foot-by-5-foot windows.
The 3M indoor window insulator kit provides an airtight seal to keep the heat in and the cold out (click to enlarge).
Made by 3M, this indoor 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 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 Secure Seal
Included with this kit is a 1/2-inch-by-12-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 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 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.

It is also optically clear, not at all diffusive. That is another absolute must. I was simply amazed at how this product brings all this together into a cheap, effective solution to drafty old windows. Someone reviewed that the tape wouldn't stick to their window frame. Probably a surface prep issue. In my application the paint was new and firmly bonded. I even had strongly curved surfaces to tape over. I found that heating the tape with a hair dryer helped conform it to those surfaces. Directions don't address that issue and for flat surfaces it's not one. This is a great product!
I used these kits to seal drafty windows in an old building. It took a little over an hour to cover 4 windows. The temperature difference is dramatic and when the plastic has been well tightened and trimmed it isn't too noticable.
I did put this up by myself. I am short, and had no problems doing it.
I have a 23 year old Andersen sliding door. I would love to replace it, but have to take the cheap route. When looking for the source of drafts, I used a lit match, and the wind coming through the cracks would blow the match out.
The first thing I did was to use some removable rope-type caulk to seal the huge air leaks. I didn't want this plastic to be billowing.
I wiped all the painted trim with a paper towel saturated with rubbing alcohol. This was recommended to prep the surface for the tape.
Because my sliding patio door didn't have any base trim to attach the tape to, I had to get creative. I purchased a piece of white PVC trim (1 1/2" x 1/2") and cut it just a smidge larger than I needed. This held it in place by tension. I have carpeting in the room, so I couldn't attach trim to the floor. This trim was even with the rest of the wood trim around the door. This allowed me to run tape on all four sides.
The door itself is recessed about 1 1/2" from the other trim. Although the 6 ft. trim piece fits with tension, I cut another piece of the trim to back it up and fill the gap. I used sticky back velcro to hold it in place. I am hoping to upload a photo to show how I handled this, as it is hard to describe.
I should mention that I removed the door handle. The inside handle is connected with screws to the exterior handle. I thought the exterior portion of the handle would fall off, but it didn't.Read more ›
I installed this product on 10 windows having shades, and after the first one, when I made all the mistakes, I was able to do them in 5-10 minutes each. Here's how (and how to avoid the mistakes).
First - and this applies to any window - realize that when you first roll out the film to cut it, you are cutting to the width of the window (+2 inches). When you unfold the film after cutting, it unfolds to 5 feet, the maximum length of the window. After you install the film, you can trim off the leftover film at the bottom of the window.
Start by cleaning the wood surface with alcohol. This is not part of the packaged instructions, but it will surely help the tape to stick. Also, don't expect it to stick to flaky or badly alligatored paint. Now apply the tape. You will be going around the inside of the window: across the bottom sill (facing up), up one side (facing the other side), across the inside of the top (facing down), and down the other side (facing the first side). Do not start the tape in a corner, or you will have a tough time lifting and pulling off the tape covering. Start in the middle of the bottom sill and go all the way around the inside and back to the start. Before you finish the taping, pull up the covering from the start of the tape (with a fingernail or the edge of a knife blade, then finish the tape by overlapping the start by a half inch.Read more ›
