This is the best! The kit was super easy to install, and once it's been stretched with the hair drier (I used a commercial heat gun but same results) it is completely transparent. There is literally no way to tell that this is on a window -- you see no reduction or degradation of the light coming through, and there is no distortion or blurring to give away that there's a plastic window sealer installed. It takes me about 30 minutes to install on two 70" windows and a third 35" window, including the time it takes to remove and replace the blinds. I would highly, highly recommend this easy-to-use and quality product! Read more
Our windows are old and extremely drafty. You could literally feel the draft hitting you while sitting on the couch. Our heater would run pretty much consistently. And that made for a pretty hefty electric bill my brother-in-law suggested this product. I read the reviews which I always do. This product was so easy to install and works perfectly. Our living room actually stays warm now, our heater isn’t running constantly and no more draft. Read more
The media could not be loaded. I’m impressed with how well the Duck Brand Window Insulation Kit performs. The film is easy to cut, the tape adheres firmly, and installation was straightforward — just follow the steps and use a hair dryer to tighten the film. Once in place, it becomes nearly invisible and creates a tight seal that really blocks out drafts. Within a day, I could feel a difference in temperature near my windows, and my heating system doesn’t have to work as hard. It’s especially useful for older windows or rental spaces where you can’t fully replace the glass. You get enough material to cover up to 10 windows, which makes it a great value. Overall, this kit does exactly what it promises — keeps warm air in, keeps cold air out, and saves on energy costs. Highly recommended for winter prep. Read more
I have never used a product like this but decided to put it on over replacement vinyl windows at the ski cabin that had the smallest air leaks but any leak is a waste of energy. I first tried to be as exact and precise as I could but learn that was not necessary. I did the other 7 windows by cutting the film with ample length, then framing in the frame with the provided tape.. all that was left was to unfold the film, pressing it to the tape as I went and no I was not precise. Even with massive wrinkles in the film once you apply heat the film shrinks up and is crystal clear. I would give this 10 stars for ease of use even if you’re not at all careful however the country of origin is a negative. Read more
This product is amazing and you will be asking yourself why you didn't get it sooner. My house is considerably warmer now with these insulation kits installed. THEY REALLY WORK ! I used a laser thermometer on my windows, before and after. I had a 3-6F degree temperature increase on average with the window film. I actually turned my thermostat down on my gas furnace by a few degrees which will make a huge difference in my bill over the entire winter. I have to admit, I was always skeptical about these, but they really do work. They aren't bad to install. All you need is a pair of scissors and a hair dryer. I got a good rhythm going and did 14 windows. I accidentally tore a hole in my first piece of film I cut. But you really can do 15 windows with it. First, I moved my curtains aside. Then I cleaned my windows and the frame with Windex. Next, this to me was the hardest part and that was putting the tape on. Separating the clear double sized tape from the white covering was hard for me because my nails are short. Once I did that, I folded the white cover part back about 1/4 inch forming a tiny tab, then placed the tape across the top of the frame. Then I did the the sides. And the bottom of the window last. I pulled the white cover tab I made off of each piece before moving on to the next section. So here's where I made my mistake on the first one. I accidentally unfolded the roll first. What you need to do is roll the plastic out as it is right from the roll without unfolding it. Measure your window across where the tape is and give an inch or two on either side. Then make your cut. Unfold the plastic and start placing it on the tape at the top. Then do your sides and follow up with the bottom. Now you're ready to shrink wrap it using your hair dryer. Set the hair dryer on the high setting and move the dryer across the film slowly. Keep it moving. Once the film heats up you will see the film start to shrink. Keep the hair dryer moving. Don't let it sit to long in once place or you could possibly burn a hole in the plastic. It helps to have a lot of light in the room to spot the wrinkles. They will all come out. Just be patient. And when you're done, it will look amazing ! Tight as a drum and just like a pane of glass ! I used this product along with painters tape to tape the seams of the windows and foam outlet covers to stop any drafts from coming in. Read more
I had a couple of older windows in my 200-year-old Vermont home that have not been updated. Very easy to use. I did it by myself on a ladder in about seven minutes. Tape is good and sticky. I did put a couple extra pieces on the corner areas after reading some of the reviews. Gets nice and tight after you hit it with the blow dryer. Kind of cool and science-y. Sometimes I have to touch it to remember it’s there. Love it because it keeps the cold out but allows all the light that I need for a Vermont winter Into my bathroom. Good product. Read more
Worked great on my windows. The double sided tape was difficult to pull stripping off but overall was what I expected and is certainly helping keep cold drafts out. The plastic is of good quality and also came with instructions. You do need a heat gun or hair dryer to complete installation. Read more
