Rated 4.0 out of 5.0 by Much warmer! So I decided to cover up my fireplace due to it being so drafty. I saw this and had the hubby go get me a pack. Opened it up and it had three individual plastic sheets. Used one, measured and cut accordingly. Followed the directions, which took less then 10 mins of my time. Instantly, the cold was gone. My husband came down stairs surprised that I had it already done and felt the difference in the living room. I'm so happy with the results!! I will be doing this every winter now. Pros: super easy to install, did the job! Cons: needs wider tape. January 21, 2016
Rated 2.0 out of 5.0 by Mehhh I have a sun room attached to the house in the back that isn't insulated all that well and the old windows leak air bad. I bought this to help keep out some cold air. Half of it is holding strong other half the sticky tape is peeling up. Used it on the outside of one window and the tape lasted a day before it peeled up. January 30, 2016
Rated 1.0 out of 5.0 by Dissapointed It hasn't been 24 hours yet since i've installed this product at a window and the bottom is already loose. i followed the directions very precisely and even took time to smooth out and clean the surface before adhesion. the only reason why i settled for this is because i could not find the 3M brand in the Ozone Park Home depot. never again will i purchase these window insulator kits!

Rated 1.0 out of 5.0 by more trouble than its worth the tape wouldnt stay on the window sills at all...better off buying rolls of sheeting and clear packing tape! January 23, 2016
Rated 5.0 out of 5.0 by A clean surface is the key I live in Upstate NY where the winters can be brutal. I have been using this product for several years now with great results. I have found that the key to successful use is that you must make sure the areas around the windows you are planning to cover must be absolutely clean and free of any kind of dirt, dust, grease or grime, including any cleaner residue. I have found rubbing alcohol on paper toweling works the best to do this. You may have to clean around a window twice, depending on it's location (i.e. a kitchen window). Allow a few minutes for the alcohol residue to dry up and the tape sticks very well. The savings I see on my heating bill are way beyond the cost of the product. Well worth the money!

Rated 1.0 out of 5.0 by Avoid at all cost I spent about an hour cleaning/dusting and applying 4 of these to my windows and by the time I finished the 4th window I noticed that the first 2 has completely let go, I went to HD and got a full return on the 3pk and 9pk I had purchased and instead got the 3M kits like I had planned in the first place. Don't try to save a few bucks, get the better quality ones, unlike myself who is now redoing all the windows I did this morning. Boo October 31, 2015
Rated 5.0 out of 5.0 by Drafty windows - No Problem! I live in an apartment with old, drafty windows. It gets ridiculous during the winter. Cold air just pours in through these windows. After applying this film which was a snap, no more drafty windows! This kit makes it easy and Home Depot has kits in all sizes to cover all applications. Thanks Home Depot! November 14, 2010
Rated 1.0 out of 5.0 by Does not attach to window I applied this film to 10+ windows. Each and every window had the film detach. I had to remove the film and the tape and replace it with 3M tape and film. The 3M stuff works beautifully. DON'T BUY THIS STUFF!! October 31, 2015
