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.

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
