Duck 1163221 Indoor Krimpfolie Isolatie Kit Isolatie, Helder, 10 Vensters

Living in Canada in the winter my sunroom was always freezing cold. I installed this and am astounded how well it works. I ended up putting it on two more windows inside the spare bedrooms and it has made a massive difference. The whole house is warmer, and the furnace isn't running as often. Its been a week and already I am looking forward to seeing my power bill to see how much it has dropped. It's probably going to pay for its self in the first month. I highly recommed it.

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.

I have 11 single pane windows which as well as letting out heat , have a lot of condensation on them in the morning . I decided window insulation would probably be helpful .I was a bit dubious of which brand to try , however I settled on duck .The first window I tried was easy to do , the tape stuck well and was easy to place , however I hadn’t checked the length of my windows properly and the film was too short 😡 I didn’t want to bother doing it again so I added a bit to the bottom 🤣 probably not ideal but still does the job . For the remaining windows I put the film on sideways which was a bit more fiddly but still easy to do .The shrinkage with the hairdryer is perfect , although be careful as I got to close to one window and burnt a hole in the film.Even with my two mishaps (my fault not the fault of the product ) it is doing , what I hoped it would .The film has been up two weeks , has reduced condensation and increased the warmth in the room .Overall easy to place ( really easy if you’re windows are less than 5ft)Photo shows one window with the film on compared with the adjacent window without it .

Amazingly helpful with sealing the windows in Melbourbe, where they do not believe in insulation nor double pane windows. Although it had to be done from the outside as my windows are openable, therefore, without a flat surface. I am now able to sit my the windows and not freeze. A hair dryer is a must for the installation process.

I love this stuff! It works perfectly for drafty windows - Like in apartments. Should also keep out bugs, dirt, and perhaps a light sound barrier.Installation is beyond simple. Anyone can do this, and alone. There is plenty of room for error.As it happens, I had perfect application on four 3x5 windows. Flawless. But, I want to talk about something that I've noticed a few others mention that I was curious about myself. (I got on here hoping to find an answer, and I didn't. So I'm going to try to answer it)The first day after installation of these, I noticed sound coming from them. It wasn't from *wind* like some people assume. I think it was a mix of static and tension, (and maybe sunlight?) Though, I heard it at night too. The sound - slow, soft crinkling of a potato chip bag.. Usually every 20 seconds or so.It's the time that leaves me to believe it's some form of static discharge.This went on for two days before I decided it wasn't 'settling' and I started to think of what was causing it.Well, if this were permanent, you can bet I wouldn't be giving this product 5 stars. So here's how I fixed it.Remember how I said I had a flawless application, but this product leaves room for error? (if you skimmed ahead, that's what you get for being impatient). Well, my application was too perfect. It was as tight as a drum, stretched all across each side perfectly. I had no problem removing an entire side at a time and repositioning it so it was half an inch closer to the window (loosening the fit). I didn't do this on ALL 4 sides, just two. After doing this, the sound was gone! Bam! It's still pretty tight, but nowhere like it was before. It still tight enough to where you can't see it unless you have a lamp in the reflection. Otherwise it's invisible.I'm not sure why or what combination of things caused the sound, but after repositioning it to be ever so slightly looser, all is golden!So my advice, Don't get it drum tight the first time around... And if you do, and experience this noise, just loosen a side or two and it should go away.To apply, I put tape on all 4 sides, then cut the proximal size of plastic, started at the top, and worked my way to the bottom. I didn't have any issues, but the tape is strong, sticky and forgiving. It sticks great to my paint, without removing it (the paint) , and can be restuck many many times as far as I can tell.I did it alone, and you probably can too. Two people would make it easier, but it isn't mandatory.Having a sharp pair of scissors comes in handy. To trim the excess, I didn't trim, but glided the scissors around to leave as clean of an edge as possible.I also didn't have a hairdryer, but I did have a space heater which worked perfectly, Probably better than a hairdryer.It came with two rolls of film. I did 4 windows and have enough left over from the first roll for one more window, and haven't touched the second roll. (Each roll should get you 5 windows, and I'm on track to get just that). I also have more than enough tape left over and have begun to use it for home projects.It's super strong, invisible, thin, and removable. I love it on it's own and would pay 10$ just for that.****and if you want to get creative... Consider attaching a neodymium magnet to your blind controller in a fashion that could allow you to open and close them as desired, if you so wished! I haven't tried this but I know it would work with some creativity (perhaps super gluing a flat magnet to the base of the spinny thing (attaching it so the N/S polarity is horizontal/perpendicular to the thingy) .. So that you can manipulate it by rotating an equally strong magnet near it (while keeping them apart of course - using your hand as a barrier). If you've played with high powered magnets before, you'll understand how this could/should work. an interesting thought to fix the fact that you can't control your blinds once the film is on) Similar thoughts apply to attaching a magnet to the draw cords (though, they may be too heavy for such ambitious ideas) But adding a weight to the draw string could be a way to counter that. Who knows!I have one more window to do, and I will test this out myself and update with whatever results I have.. Even if they are just awful.
