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.

I used this window insulation film on our 21 year old home and it made a noticeable difference. Cold air used to come through the window in winter, but after applying this, the room stays much warmer and it helps reduce heating costs. The price is good and installation was simple. I just wish the plastic were a bit thicker, but overall it works well.

Very impressed so far. Solved an annoying condensation problem I was having on single pane windows. They should make this in a translucent/etched version. Great product!

I bought this because one room in my home is freezing in the winter and way too hot in the summer. I honestly thought I had a wall-insulation issue, but I tried insulating the windows first, and wow. The difference was immediate. The room finally feels normal. I’ve never used a window insulation kit before, but this one was really easy to work with. With two people, it’s simple to line it up and get it nice and tight. And if you mess up, a blow dryer fixes everything. It shrinks perfectly and looks clean once it’s on. Only downside: you can’t open the window afterward, but for the comfort upgrade, I’ll take it. At this point I’ll just replace the window when I’m ready. If you have a room that runs too cold or too hot, try this before assuming you need major insulation work. It’s cheaper than installing a new window and works instantly.

It works. BUT. Follow these pro tips for best results: 1.) lay the 2 sided tape. If you go ALL the way around your window in one fell swoop, use a razor blade and score the window corners. Every time there is a 90 degree angle, score this with the razor. The reason is this is an area of weakness, and if it is going to pull off the tape, this will be the first place because there's usually a bend in the tape here. Scoring the tape will prevent this. 2.) While using a blow dryer DOES tighten the plastic, and make it wrinkle free.... forget this step. It's nice for about 3 weeks, but once it gets cold, the plastic tightens more and pulls off in some places. Leave it wrinkly if you're putting these in to keep out cold. 3.) After you lay the tape and have your MEASURED section ready (give yourself 2-4 inches BEYOND you measured, put the plastic up 1" INSIDE the tape. This gives you room to move on the other sides while you put it up, and if you do decide to not listen to me in #2 above, it gives some play in getting it set the first time. Even without using a blow dryer to tighten, leaving a little play keeps strain of the double-sided tape, and keeps you from putting these up again in the winter. My windows suck and I can see the plastic move at times with extreme wind... but now with these up, my furnace can actually keep up, whereas it couldn't last winter. Last tip, don't get the Amazon Easy package, get the name brand (here on amazon too). You're just paying $3 more for a brown cardboard box rather than a duck brand cardboard box... ***update 11/30/18*** These are still good, and working well FOR THE WINDOWS I DID NOT TIGHTEN WITH A BLOW DRYER. I've had to re-tape almost every other window that I used a blow dryer on.... as it gets colder, the plastic tightens more and pulls off the sides in places Never mind using the blow dryer to give the crystal clear effect. If you are putting these o. to keep out the cold, just put them up with a little slack and you'll be fine.

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.

My house is 100 years old and everything is original, which means windows let everything in. This product is great, easy to install even if you are alone, great quality and works amazingly! It’s goes a lot further than you’d think which for a house full of windows is a good deal!
