Keep the Heat In and the Cold Out
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.

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

It's smart for a couple reasons. Of course, the concept is simple: trap the air between the glass and the room and the air becomes the insulator. But it's all in the implementation and that's where this product shines. It uses double-sided tape that isn't so sticky that it will pull of paint when removed. Have to get that right and they did. The real attention to detail is the film material. When installed, it better not look tacky. So they formulated the material to shrink just enough to tighten it up to pull out the hard and soft wrinkles, but not pull away from the tape! Don't worry if the tape and the film lie on perpendicular planes. The film won't pull off when it shrinks. It's resilient enough not to overcome the film-to-tape adhesion. Again: brilliant.

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!

This kit makes it easy to quicky insulate just about any reasonably sized window you may have. The kit includes one large sheet of plastic and 2 rolls of double sided tape. You apply the tape around the frame of the window you want to insulate, cut a piece of plastic and then apply it to the tape. Once you've done that you just need to use a hair dryer on the plastic to get it to shrink and tighten in your window frame.
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.

This is a great product, but what do you do if you have window shades or curtains that go across the window between the inside trim pieces? All the videos I have seen show the film being placed across the front of the entire window casement. You can do that, but then you can't adjust the window shades.

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.

I've spent the first part of this winter suffering because of drafty windows in the bedrooms of my new (old) home. I found this insulation kit from 3M, ordered it on Monday and it arrived on Thursday! In about 1 hour I had 4 windows sealed. I found it simple and straightforward to follow the instructions and it worked exactly as described. It's noticeably warmer in my bedroom, and I haven't adjusted the thermostat.

One note however, there was only enough plastic to cover 4 windows, not 5, and my windows are almost exactly the size given on the label. It was okay though, I covered the 4 worst offenders so it wasn't that big a problem for me.

Style Name: IndoorSize Name: 5-Window
We have 2 gigantic windows + a patio door in our living room. Did a lot of research and chose 3M given the positive comments on the double-sided tape vs. the cheaper Duck brand (Walmart) and Home Depot/Lowes equivalents.

First off, the instructions on the box were just awful. Going by these, our first attempt at installing was a disaster. Spent a hour trying to tuck the film into the nooks and crannies of the window/frame, putting tape everywhere and then blow-drying. Got absolutely nowhere and was 5 mins away from giving up and returning. What we didn't realize is that the film is not supposed to stick to the window/frame like shrink wrap, but create a barrier that covers the entire window cavity...perhaps my stupid mistake, but I had no idea!

Having calmed down and taken a break, we tried it again and had much more success. The only other thing is that I to keep the blow dryer as close to the film as humanly possible (but without touching) for the film to shrink and become tight. Worked in the end though and was tight as a drum.

Very happy with the result (although not as crystal clear as other reviewers have said), but would recommend youtube research and patience for first time installers like myself!
