5.0 out of 5 stars My office is warm and toasty thanks to this stuff!, December 18, 2000

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.

5.0 out of 5 stars Designed with Attention to Detail, January 21, 2008

By	J. Small "A Bright" (Midwest USA) - See all my reviews (REAL NAME)

This review is from: 3M 2141W Indoor 5-Window Insulator Kit (Tools & Hardware)

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!

5.0 out of 5 stars Great product, easy to install, February 10, 2007

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.
