DUCK Brand Rolled Shrink Film Window Kit, Insulates up to 10 Windows, 62 in. x 420 in, Clear (287406)

Buy this pack, the tape actually sticks, the plastic film gets nice and tight when using a hairdryer. I covered 7 sash windows with a single pack, and still have some spare. Totally worth the money.1. Clean the windows and the area you will stick the tape.2. Apply the tape accurately and peal the top left and side back about 4 inches, leave the backing tape sticking out.3. measure the height of the window with tape, and add about 5cm, cut the plastic to the length.4. Apply the film to top left while ensuring the left side is over the tape, carefully maintain the light tension while you peel the backing tape and press the film on about 30cm at a time. (Or when you get good you can peel the top tape totally and then apply)5. Hair dryer the taped areas esp. any wrinkled areas, then just steadily the whole area, keep the dryer moving slowly.6. cut off excess, replace blinds or curtains etc. and pretty good results.

It is so clear that we genuinely forget it is there. It has stopped all the condensation on the old single glazed windows and helps keep the heat in. It took a few windows before I figured out how to best overlap the corners with tape as these bits can pull free if not done well or the window pane is not properly cleaned and the shrinking is overly vigorous but where I've got it right it's the best glazing kit I've seen.

I compiled with the instructions but I just couldn’t get it to work twice but there after fantastic results.Put tape on the wood only.It doesn’t work on metal or wall well I could not get it to work.Make sure you overlap the corners.Cut slightly too big the sheet you must.Start from top and work your way down the window both sides if you can far better fit.When on do not cut off excess.Use your heat source and get the sheet stretched so clear then if you can leave the excess honestly it’s so much easier. I tried with scissors a stanly knife some times it ripped into the bit you wanted to keep. Very frustrating so if you can just let it you can’t really see it as long it’s not too much.

The media could not be loaded. Really recommend these if you have single glazing. Were a bit fiddly to fit and not stick to itself and to cut and fit straight. However once fitted and (I left mine over night before) tight - with a hairdryer - just spot on! No condensation, good improvement to heat retention in the room, sound improvement, very hard to see (creates a very slight hazyness), just a really good product. Can't yet comment on how they will come off once they are no longer needed but we'll see. Really really good.

I tried a few brands of window film and definitely had the best results with this one. You cannot see it unless looking very closely. The tape sticks great and I have not had any loosen over at least a month, as I did with another brand within one day. With cold weather and single glazed windows this made a difference to loss of heat. Not incredibly but enough that it was well worth it. Instuctions are good but watching a video made it much more clear and turned out to be quite easy. I left mine overnight before using a hairdryer to tighten to plastic (which takes out all wrinkles! It's quite amazing and satisfying) and trimming the edges the following day. Cannot tell it is there, especially on white window frames.

Ok - served a purpose. Looks terrible.

Only been applied about a week ago to three small windows. So far, the rooms are warmer and the noise from outside is noticeably reduced too. Hopefully it will stay on and working all winter.

I really did not expect this to be SOOOOO good. I have a pretty humid flat. Like, puddles of condensation under my windows, level of humid. I struggled a lot last year because I had to clear the water every day with a towel but there was just so much! I bought this thinking it would help a bit and maybe make my flat a tiny bit warmer, but it genuinely got rid of all the condensation. I have had it for almost a year now and they are all still there, no issues whatsoever. The application was a bit annoying because I have a lot of big windows, but not challenging at all. I did a lot on my own and some with a friend. Either way is doable (although 2 people is definitely better). If you have a very humid place and there is condensation in your windows, get it. It is a really good product and does the job. Seriously, cannot recommend enough
