Duck 284351 Heavy Duty Isolatieset met 3 ramen, rood

Out of the box, you can tell this film is approximately twice as thick as regular Duck shrink film. I have a couple windows that are draftier than the others. This film is perfect for those and this will be my film of choice in the future. The tape seems to be the standard Duck window tape (that comes with the regular film) but it holds just the same. This film is just the tiniest bit less glass-clear than the thinner film, but not noticeable once it was shrunk & the curtains were back up. From the outside, I cannot tell any difference at all between the regular film & this thicker film. That's a plus for me, as I don't want the place looking too hokey from the outside. I have used & liked 3M window film in the past, but Duck is my choice because it performs as well overall, but costs less. I am very happy with this product. Thank you Duck :)When the directions say to **remove tape at end of heating season**.....make sure you do it. The longer you wait, the harder is is to remove the tape residue from the window surface. My windows are white vinyl. Normally stuff cleans off the surface easily, but not if I leave the tape up too long. The sticky substance starts to become semi-permanent. This process seems to occur over several months, to longer. I'd say it takes about 8 months for this to start. It prob depends on temps, humidity, UV from sunshine, etc as to how long exactly. I have left film up to three years on windows I never open. In one instance the film let go of the tape finally, but on 2 other windows it held the entire time. I only needed to remove it because the film was pretty dirty. If I had known how hard it was to remove the tape residue, I would have left the film in place and just cleaned it with window cleaner & a microfiber cloth, like I do with glass. When I remove the tape after the recommended 6 months or so, I have NEVER had issues removing the film & tape from ANY surface.The secrets to success with shrink film kits is PREPARATION. Follow the instructions where it says to CLEAN the tape surface properly. This does two things that are vital to the process: 1) making sure the tape holds the entire season and 2) making sure the tape comes off easily when you want to pull it off. On my vinyl windows, I first wipe them down with window cleaner, then I quickly swipe the surface with rubbing alcohol on a cotton ball. On wood windows I did the same, altho I tested both first and didn't allow either to be on the finish surface anywhere near as long. On finished wood surfaces it is VITAL to take this stuff down as soon as possible in spring. If you follow the instructions when it says to do this, you'll be fine. If you leave it up longer you run the risk of having dried tape residue that only comes off with lots of spraying, soaking, scraping and elbow grease.I have used this product for a few non-window applications. In my bathroom there are two openings in the ceilings, an attic access and a disabled recirculating fan. The film worked great to help control the amount of heat that was escaping, and made the bathroom feel much warmer. Those surfaces are *semi-gloss* paint. The tape came off fine when I removed it as recommended. I would be leery of using this tape on any kind of flat or satin wall paint, for example standard flat ceiling paint. Test first, since this is not a labeled use. The less glossy/more porous a surface is, the harder it is to get the tape off without damage or tape residue being left behind.

Easy to use

Easy to install, looks good but would prefer high transparency in the film.

Llevo 3 años comprando en épocas invernales este producto. Casa año lo coloco mejor, ya que tiene su chiste.En cuanto a aislante de frío es buenísimo, claro, no esperen que no haya frío en sus habitaciones. Simplemente disminuye el frío. En mi caso un 50%.

Installed in basement, located in Ontario Canada. Current temp is -8c1. I just installed this today and not sure how much of a difference it will make. It does feel warmer.2. Product feels like good quality and install was relatively easy. 4/10.3. Make sure you have a hair dryer or heat gun handy. Tape did not stick on surface when it was cold. Heated surface, then stuck it, then slightly heated up tape and pressed it firmly, pulled off top layer and slightly heated it again before I put up plastic. Overkill?? Maybe. But she's a stickin'
