Duck Brand Indoor 10-Window Shrink Film Insulator Kit, 62-Inch x 420-Inch, 286216

I haven’t had the need to use plastic over windows in awhile. The kits used to come with folded sheets of plastic. This kit actually comes with a roll of plastic. It is so much easier! You start at the top corner and roll it across, then just unfold it down the window. It’s so much easier to maneuver. It has made such a difference in room temp, it’s crazy. My living room was actually at 49, with this plastic up it fluctuates between 68-70 now which is perfect. I’m planning on leaving it up for summer to keep the heat out and lower my a/c costs! This is a great kit, easy to use and works great. They also give you plenty of tape which is very sticky and the plastic is strong and very clear also.

I bought the Duck Brand Indoor Shrink Film Kit because I really didn’t want to take my window AC unit out for the winter, and this has worked perfectly. Once applied, the film creates a tight seal and keeps cold air from leaking in, which makes a noticeable difference in the room temperature. The kit is easy to install — just follow the steps, pull the film tight, and use a hair dryer to shrink it. Even with the AC still in the window, the plastic tightened up smooth and clear. It also feels durable enough to last the entire season. If you’re like me and prefer to leave your AC in year-round, this is an affordable way to block drafts and keep your room warm. It does exactly what it’s supposed to do.

This window insulation kit definitely helps keep drafts out and rooms warmer, but it takes some patience to get it right. The film is clear and fits nicely over the windows, and once sealed, it makes a noticeable difference in keeping out the cold. The tricky part is applying heat. You have to be really careful with the blow dryer, I accidentally ripped through a few pieces while trying to shrink the film. The plastic tightens up nicely when done correctly, but it doesn’t take much heat to damage it, so go slow and keep the dryer moving. Once installed, it looks clean and holds up through the season without peeling off. It’s a good affordable option for older windows, just be gentle during setup.

I have used Frost King film for decades. Although it never split, the film was extremely thin. The Duck Brand here, has noticeably thicker film, but far more importantly, the tape sticks to wood and aluminum FAR better than the other brand. It has shrunk tight as a drum, is invisible, and looks great! Costing less than the Frost King makes it a great value. The only negative I found has been praised by others. This kit, 62-inch x 210-inch, comes on a roll. For me, this makes installation more difficult with the roll remains attached. Had I cut the total width first, it would have been a non-issue, I'm sure, but I wanted to ensure I did not cut too short and ruin the roll for my use. I have attached photos of my bay window installation.

I highly recommend you read the entire directions, and also the other reviews. By reading the very helpful reviews I was able to learn from people who have done this before. It was so worth the time. Speaking of time... that's really the main thing you want to dedicate to this cause - time. If you rush it, it will be unpleasant and not work well. Get your hairdryer ahead of time. Clean and dry the areas to be sealed. If you are doing an old-fashioned door with a checkered=pattern window, like me... Measure/cut to leave enough extra to seal over the grille [cross pieces on the glass]. I just covered my windows on the front and back door that have the glass checker-board panes. I had to cut the tape into 12 pieces. With this type of application the tape had to go on the glass instead of the sill, because the sill is about 50 years old and if I rip off the paint, there is gonna be hell to pay. No worries. It worked on the glass and the draft stopped immediately. There is an issue I can see, and it was mentioned by other reviewers... You may need to use more tape than provided because in some cases the tape gets touched and loses it's stickiness before you are ready to seal the plastic. No worries, just put another piece of tape and don't touch, put that plastic on fast and don't get too many finger-prints on everything as you try to size it. Fingerprint grease is obviously a glue destroyer. For that it's best to do one section of tape at a time. I've done four windows [counting the two doors as one window] so far and still have plenty of tape left. For best adherence, use the dryer to warm the surface you are applying the tape to, especially if it's glass. Then use the dryer to warm up the tape just before you press the plastic onto it, but not too much or it will dry out. The good thing is that this isn't like saran wrap - if the plastic folds on itself it doesn't stick - hence the tape. I also covered 3 regular, modern windows where I could put the tape directly on the clean sill. Worked great, piece of cake. As far as how much of this stuff there is... definitely enough for 5 windows. In my case I've used scraps on the back door - piecing two remnants from the other windows onto this one, since it's rarely viewed it doesn't need to be perfect. It turned out pretty good and that means you can make at least six window covers if you are willing to be creative. One more thing if you do have very leaky windows like these old doors I'm talking about, you may see what I see... that is condensation pooling at the bottom of the plastic which is pulling the plastic away from the glass in those sections. The way I see it... That is condensation that would be in my house, I'm glad that cold water is in the plastic and not in my air. However that does mean that in order to keep the doors from getting more rickety than they already are I have to sop that water up from time to time... and perhaps replace the tape every so often. No worries. The main thing is my heater goes on about half as much as before. I haven't got an electric bill since installing, but I don't think it's rocket science - that's got to translate to savings worth more than the $8 this kit costs. I will never go a winter without it again. Even if there was no cost savings, not having an uncomfortably drafty house is priceless.

This is my first time using something like this but this window sealing kit has been great at sealing out the cold from our house! We have an older 70's house that still has the original windows (single-double pane, no insulation). Which is a killer on our heating bill here in Canada until we can switch out all the windows for newer ones. This sealing kit was super easy to install and is barely noticeable (the only noticeable part being on the window frame if you squint). Drastically could feel and see the difference it made to sealing in our heat! Even going as far as keeping our house from overheating too badly from the sun during hotter temperatures. Overall, would recommend!

This shrink film kit does an excellent job of sealing out cold air, making a noticeable difference in my basement—it’s now much more comfortable to stay in! The installation was straightforward, and the film shrinks nicely for a clear, tight seal. The only downside is that the kit comes with more film and tape than I actually need. It would be great if there were smaller size options. However, the extra materials could be useful for future use or larger projects. Overall, a great product for improving insulation and keeping the cold out!

Es importante ver tutoriales para saber cómo cortarlo e instalarlo. El producto es muy bueno y funciona para aislamiento de frío y viento de ventanas. Se requiere de ayuda de dos personas para facilitar la instalación

No complaints with the installation, some of my windows are sliding sash windows so it was a bit fiddly to install but that's not the fault of the product. Pretty forgiving of bad workmanship as a blow with the hairdryer takes out the creases and gives a great finish. Definitely notice the difference in terms of insulation and sound proofing. Worth doing if you can't fit double glazing for any reason.

Easy to use very effective keeps room warm also helps with road noise
