Duck 286218 Extra Shrink Film Insulation kit, Crystal Clear, 1 Patio Door/Large Window

I read the reviews and watched the instruction video several times and didn't have any problems at all with installation. I have a large patio door that's single glazed with minimal sealant around it. I put this over the one window (left) to see the difference. It still collects a little condensation (-2 celcious outside that day) but nowhere near as much as the uncovered door

I have just moved house and have discovered a terrible window that needs replacing. Every morning we wake up to full condensation and a puddle on the windowsill.Bought this to try and help, and it definitely has. Still get condensation, but no where near as much. Haven’t had it long enough to test in true cold weather (reviewed in November after 1/2 months), but for now it is helping.Only issue is the tape that was supplied was truly awful and didn’t stick anywhere, even after cleaning the surfaces thoroughly. Luckily we had our own double sided tape that has done the job.

I was expecting a big faff and a slightly cheap product, but actually it was pretty easy to do and it works. Setting it up took a little getting used to - by window three I was a lot quicker - and it's obviously not like real double glazing, but it definitely helps with keeping the cold out on our rattly sash windows, and seems to have eliminated condensation completely - I would do it again for that reason alone. It has also cut down on street noise a lot.The size of the plastic was generous - a few centimeters bigger than advertised, as was the amount of tape. I didn't measure it, but I expected the tape to run out as I did several small windows, rather than a a few big ones, but I got them all done, used pretty much all the plastic film and had a little tape left.I haven't had to take it off yet... but so far am very pleased with it.

Product not bad but I have requested invoice for over a month and not received it. Customer service is extremely bad

When unfolding the sheet there only seemed to be half the amount. I did wonder if it was still double thickness, but despite trying all the tricks I knew I couldn't separate it, so assumed I had been sent the wrong size. Only on the second window did one bit start to separate on its own to confirm we were indeed using a double thickness. However we were still unable to separate the final piece! So we have half the windows done at double thickness, which is a bit annoying, and not as clear as I would like. But it looks like it will do the job. Just hope removing the tape doesn't take all the paint off in the spring!!

A few points to add to what others have saidIt costs less on the USA Amazon web site , £12 rather than £17, so rip off UKContents of the box are underwhelming, a sheet of thin plastic and a roll of tape with a retail value of perhaps £5 ?My windows are 1m x 1m. So enough plastic sheet for six windows but only enough tape for 2 whole windows, I ran out of tape on the third window and had to buy extra tape.I might have gone to 4 stars if there was enough tape because the sheet does go up well, it looks a tiny bit misty but I was expecting that.

Bought for my patio door but the downside was that there was not enough tape (It's a double door with 2 side panels which had to be done individually so doors could be opened) Thankfully I'd bought the window kit too so was able to complete. Once I'd gotten the hang of it, I found it quite easy to attach it. It was easier once I realised that a little bit of slack would disappear once the heat (from a hairdryer) was applied and that using a Stanley knife rather than scissors for trimming the excess. Whether it is effective ..... only time will tell but I am hoping that it is.

This is the first window that I have used this product on and the result is so clear plus the tape is easy to peel. I would recommend removing any tools that you might need before applying as my scissors are now a modern art installation behind plastic until Spring - oops! Seriously though, I had a long cardboard tube that I used to roll the film around and used this to help control and apply the film as I rolled it down the window, ensuring it was properly adhered. I would recommend using this technique. Four more windows to go and only one pair of scissors left! Will put up another review in a few weeks to see how effective it has been against cold and draughts.
