Used on both my patio doors and all 10 windows. Excellent quality, easy roll across and cut design, thick, sturdy, tape in place holds perfectly, great value for money, when I blow dryed sealed it was taunt, clear, effective. Perfectly shrink wrapped.Drafts were immediately gone. Made a huge difference keeping out the winter drafts and holding in the heat. Would definitely buy again and highly recommend.I bought both patio size and xl window size.

Covered the windows where a cold draft was coming in. Easy to apply and works great.

The Duck MAX Strength Window Insulation Kit is a game-changer for anyone with drafty windows in winter. I put it up over my old, rattly panes, and it’s like the cold just gave up trying to get in. It’s basically shrink-wrap and tape—super easy to set up, even if you’re not crafty. My room’s cozier, and my heater’s not running on fumes anymore. Looks a little plasticky, but I’d rather be warm than stylish. Solid fix for surviving the freeze!

I recently moved to a new apartment, 2nd floor of a 2 family house. There are several crawl spaces that have little to no insulation due to it being an older house. The owner had them lined with insulation but during those extremely cold days, you can feel a draft coming in.I tried a few different options, including weatherproof insulation tape before coming across this. I was a little skeptical seeing how I was planning on using it for more than my windows but once I followed the quick video and got an idea how it works I was confident about the product and the quality of the materials you get.After seeing how the product worked, simply measure and give yourself some room to work as well. The height on the door was my concern but I can easily seeing this cover a window size of 5 feet. After trimming off the excess, run a hairdryer on high around the edges where the tape and plastic meet being careful as you go. The size and look aren't a bother. The tape sticks very well and after 24 hours I can say this product works great.

to be fair, i’ve only had this up for less than 24 hours, but already my apartment is much warmer. the heater turned off for the first time in a month lol. pennsylvania is about to get hit with super low temps & my windows are from 1970 & super drafty, so i got these to help prevent my electric bill from being almost $200 again. super easy to install, the adhesive works great even though i forgot to clean the windowsills, most of the wrinkles went away after using the hairdryer so we can still see through the windows clearly. overall i recommend this, especially if you have drafty windows! hoping my electric bill will finally go back down now that these are up. will definitely use again next winter!

This is a truly heavy duty product and given the quality I am very confident it will keep all the cold out.There is plenty of adhesive which I was worried about. I was planning to do a multi panel bay window so was concerned there wouldn’t be enough of the tape but there was plenty.The one negative was that the product clearly states to use a hair dryer to shrink it and give you a clear window. This works with other products but this product was too thick and the hair dryer did nothing. I did however use a heat gun and it worked perfectly. You do need to be very careful though as one time I was distracted and put a hole in one panel. You need to really be cautious with the heat gun.Once I got the hang of this film - it is a 5/5. It’s a shame a hair dryer isn’t enough because that seems to be the source of negative reviews but it’s only because it’s such a heavy duty product.
