Does a Great Job!

Last winter I had my handyman install 3-M Indoor Window Insulator on several of my windows. I was so surprised when I touched the windows with the film and felt no cold and then touched with windows without the film and they were very cold. I got brave an installed film on 2 windows myself. Ok, they weren't as perfectly beautiful as the ones my handyman did but they certainly did the job and kept the cold at bay. This year I am purchasing the 3-M Outdoor Insulators Kits for several windows and the Indoor ones for my interior windows. I will install them all myself. My one recommendation is to purchase an extra roll (or two) of the double-sided tape. I certainly needed it! And, I used some of the tape to install rubber insulation around my door as the self-adhesive on the back of the door insulation (Duck) was pitiful. The tape worked great for it. I highly recommend both the 3-M Window Film and their double-sided tape. I'm hoping the exterior film works just as well. Try it, take your time, read the directions (and watch the video), and I think you will be just as pleased as I am.

This kit works like a dream. I live in a very old apartment building. Last year our landlord gave us sheets of plastic and packing tape to try to block the terrible drafts that come in through our windows every year. It was a nightmare to try getting the plastic to work, and looked awful when we completed the windows. To top it off, the plastic did not have the best effect. This year, a friend suggested the 3M insulator kit. I read reviews and purchased it the same day. This product is a dream come true! I have very large windows, and the frames are "art-deco" if you can call it that... fancy frames with strange carvings and difficult corners. I ended up taping the top and bottom of the film to the frame, and the sides past the frame on the wall. Despite the difficult corners, the film sticks and has completely blocked out the drafts. I am amazed. When I got out my blow dryer, I didn't notice a change. However, when I started to hover on spots a little longer, I started to see the plastic tighten. I went slowly over the entire sheet of film and now it is smooth as glass. HIGHLY RECOMMENDED!!

Last year the 3M window insulator saved me $200 in propane heating costs. It eliminated the drafts in the house. I have 30+ year old double pane aluminum frame windows. One window if 96" wide. I do not have wood frames so stuck the tape right to the wall. Removed it in the Spring with minimal paint touch up required. It's super clear, heat shrinks well and not too difficult to do alone. I'm a 67 year old woman.  Just finished applying this year's kits and the drafts are gone. I expect even  better savings this year since I installed them before the snow hits.

I'm shocked to see bad reviews! I am very happy with this insulator kit, best I've tried yet. I didn't have any issues at all as far as separating the folded plastic sheet, securing the plastic, or getting the wrinkles out. The installation was easy and a few minutes with a blow dryer got all the wrinkles out, so much so that it almost looks like glass. The plastic has held tight through the first blizzard of the year without any problems at all and my apartment is staying much warmer!  Highly recommend!

While it helps reduce drafts as well as any brand, it only had enough tape for 1 1/2 windows that were 40 x 44 which is less than 300 inches - a far cry from the 1000 inches the box said was included! So we had to make another trip out and buy more tape. So the stores sale price on the kit covered part of the price of the extra tape. Then it didn't even shrink tight! It blows out when the wind blows. Will go back to the other brand I usually get. Disappointed and irritated.

tape doesn't stick

The way my windows are installed(set into the wall) requires me to put the tape and film onto the wall rather than trim as some others may do it. The tape doesn't stick well. Even before applying the plastic film to the tape, the tape was already peeling off the wall. Pretty disappointed.

I live in northern NY. Just moved into a new home and the windows were a bit drafty. Installed indoor window insulator kit on 4 windows. Stopped Draft, easy to use, clear as glass film. Would recommend to anyone.

Love it! Just place film on the tape and replace by pulling up off the tape until the film is tight. Don't even have to heat the film to get it tight. This is the only brand that is in a single sheet, so my larger windows are easy to cover. Been using it for years since I had trouble with other brands.

Impossible to separate sheets. Tape comes unstuck too easily. Least convenient window insullation kit ever.

Haven't figured out how to eliminate all the wrinkles, but the product stays put and keeps out drafts.
