Duck MAX Strength Heavy Duty Insulating Window Film Kit - Keep Your Home Warm and Comfortable All Year Round

Teresa Barnes: This has made a difference in keeping the cold air out. It was easy to install. Clean around window, secure tape, attach plastic on top, cut to size, unfold and attach sides and bottom. I followed the suggestion in another review and did not use a hair dryer. It still works well.

Chris Struc: I've used a few different brands before and decided to try this one and I was pretty impressed. The plastic was nice and thick, the double sided tape was good quality, and everything worked together well. I did manage to burn a hole through one window, but I was using a high powered hair dryer and was pushing the limits of it so no complaints.

Skyler SpringSkyler Spring: I was skeptical at first, But very pleased.
Winter months in my RV gets a lot of condensation build up in the windows. I tested it on ones that do no open, not a drop of condensation in them the next morning after hitting 30 degree outside temp and maintaining 70 degree inside. Even just starting with a few windows for a test run it also helped keep the temp up in the RV easier.
Pretty easy installation. I did one the way everything sits, second one I decided to remove the trim ring inside and that made everything much easier and smoother especially with the windows in the bunks.
Best bang for the buck for window insulation

Ms Mare: Omg!! The best! I was dreading needing to put plastic to my windows getting prepared for winter (in Texas) right🧡but this only took less than 30 min. And it’s clear, tight and in place!! The price is well worth it!!! All the supplies are there (without the hairdryer) but I didn’t need that! L love this!!!! And waiting to see if it will keep the heat also!!

Amazon Customer: Works great, plastic looks robust. The plastic in not as transparent compared to the one I bought from a hardware store last year.

Sarah: Other than rolling it out wrong at 1st, which I thought I had placed it correctly, it came off and I could reposition. After that it was just a matter of lifting and tighning then using hairdryer on hot setting. I sit beside this window so it has made a big difference, as chill is less.

Ashley mcleanAshley mclean: Easy enough to use, did it on 4 windows by myself 2 large and 2 medium size. Would be easier with 2 people for sure though I found the adhesive take stuck better to the vinyl on the window then it would on the painted trim. Don't really notice it's on there once it's heat shrunk.

COKat: This plastic, for sure, is thicker and insulates better than other brands I have tried. However, that also makes it less transparent/clear than those other brands, and it does NOT "shrink" at all with heat, or very very little. So, any lines or wrinkles are not going away. All the brands are all a pain in the butt to get onto your windows without some wrinkles, but you sacrifice better insulation here, for less clarity.

Mommyof2: There is a draft coming from my daughters window so I purchased this until we can get her window replaced. I was skeptical if it would work based on reviews but just took the plunge and glad I did. The plastic is thin but thick enough to hold. I didn’t use the tape that came with it since I didn’t want damage left on my walls so I used painters tape to take it down. It works and the plastic is holding. Her room is warmer now.

Alexx: This year I splurged a bit to get this stuff instead of the usual thinner stuff.. and holy cow, the difference.

The plastic itself is a perfect thickness to keep all the heat in and my kids can't poke holes in it just by poking at it (which they did all the time with the thinner one last year). The tape actually sticks as well, I didn't have to go buy double-sided tape separately. I will be buying extra since I have TALL windows and this just comes a little shy of the length of my windows, but honestly that's my own fault for not measuring my windows.

This product is great!
