MEFENY Window Insulation Kit, 1.6m x 10m Indoor Fit Clear Rolled Insulating Shrink Film Draught Excluder Stop Cold Condensation, Secondary Glazing Film

Fiddly but once installed works well on my back door it’s double glazed but still had a cold area as glass does but now installed 100% better, I think there may be an issue removing the double sided tape for th summer but bit of elbow grease should be ok overall don’t be frightened to buy

The sticky tape provided isn't the strongest. My windows are old and so the frames aren't perfectly flat and have imperfections. The tape doesn't work well with this, and so I would consider this if you have old frames as this has meant the film doesn't stick well and gaps have formed after a short time rendering the film useless.Initially, when first put in the windows, the shrink wrap worked well! One one window where I have had most success, the film has also drastically reduced condensation build up too, which is v positive.I do conceptually like this film and for newer single glazed windows I would recommend, but for me, I need to reconsider a different solution as the tape just isn't strong enough to support the pull of the film once its been fitted to the windows.

Not all of it is clear, some parts had white lines through it, so you can tell its on the windows, also has a very very faint haze when looking out the windows.Much easier to install than the folded up packets that are available,Shrinks easily to remove wrinkles when heated with a hairdryer,But it didn't last more than a few days before it started coming away in places from the windows,Maybe I overly heated it and it made it to tight???As all windows + where tape was placed was cleaned and dried before applying.Whist it was a faff having to keep re applying it with new tape it did work well over winter to insulate the windows,& best of all it stopped ALL the condensation forming,No more having to window vac and wipe the glass and ledges every morning!I have just taken it down ready for spring and in some places where the tape has stuck on well its proving extremely difficult to remove and has gone yellow, which looks unsightly.Even with any negative points I would definitely re purchase this again next winter just to avoid all the condensation.

I purchased a similar window kit like this but sent it back as didn't seem very good. This one is perfect and been used again for the same window 2 years running. It is fiddly to fit and even my second year of fitting the film wasn't perfect but still works.Stops condensation appearing on the window and is a good insulator. You do get condensation on the outside of the the sealing film in the room if the condensation is really bad because this film stops condensation appearing on the windows but doesn't stop condensation itself.

Useless product. It doesnt do anything. It only accumulates insects inside the window

This is value for money and makes a big difference in cold weather

Did 11 windows with the one roll including very large window similar products don't fit, double sided tape wider than most included with other brands, did get a couple faint stripe marks on some of the plastic but seems the case on all these products, will buy again next winter

Not easy to install does not stick well it looks awful nothing like they show in picture but the company was very happy to advise me on how to do it offers me a new roll to try again or a refund their customer service was very good responded quickly to my complaint
