Duck MAX Strength Window Insulation Kit, Winter Window Seal Kit Fits up to 10 Windows, Heavy Duty Shrink Film Cuts to Size for Easy Indoor Installation, Window Tape Included,62 In. x 420 In., Clear

I live in a 200 year old house with the crappie at windows ever made. Sashes coming out on multiple windows, cracks etc. needless to say my electric and gas are high. This kit does four large windows. The material is thick and it cinches tight as a drum when you put the hairdryer on it. Acts like a storm window and it’s hard to tell it’s there. Note: clean your windows first. You’ll see everything. I bought two more kits to do 8 more windows and I’m not taking it down ever until I take a mortgage out for windows. Highly recommend. Easy, inexpensive and from the results I can feel immediately in the first room I suspect my power bills will go down.

Works so easy. I love it so far.

We didn’t end up using this ourselves, but gave to a friend who said it was easy to apply and worked well throughout winter in a normally drafty home

The best piece of advice is to follow the instructions (they are very simple) and have an extra set of hands to help install to make sure the plastic doesn't get stuck on the double-sided tape and to help to make sure there's less wrinkles. To get out the wrinkles, the hair dryer needs to be on high heat, but don't get it too close to the plastic for too long, because it will burn a hole in it. (I just popped another piece of double-sided tape and plastic on top of the little hole and it sealed fine) I can already tell the difference of heat retention in my 1937 home with original windows. This is also a really great renter friendly solution. I bought the pack for 10 windows, but I had just enough supplies for my 11 windows.

DISLIKE NOTHING AND WOULD TOTALLY BUY IT AGAIN

I was never good at installing window insulation. The tape is such a pain. I finally managed to install the film. It is pretty thick so the heating and tightening does take time. I know with it being thick you get more insulation.

Worked great. I was very skeptical of it. Sealed very well. Tape stuck great and can see out it almost like it’s not there. Very clear. Very worth the money.

Nice thickness and thought a roll would be easier to use than measuring and cutting to size BUT, you need two people in order to keep the roll from constantly coming apart. Now I just cut it to size otherwise there is a lot of waste.

The plastic sheeting/film shrinks very significantly under heat, minimizing the wrinkles that can occur if you don't get the film on the window exactly right, so the overall result is very forgiving and looks great.In addition, the tape sticks really well to both the film and the window.Overall a great result at a very fair price. Totally satisfied.

Easy enough to use, did it on 4 windows by myself 2 large and 2 medium size. Would be easier with 2 people for sure though I found the adhesive take stuck better to the vinyl on the window then it would on the painted trim. Don't really notice it's on there once it's heat shrunk.

I ordered the 10 window version but when it arrived the film was dirty and had marks on it.

This year I splurged a bit to get this stuff instead of the usual thinner stuff.. and holy cow, the difference.The plastic itself is a perfect thickness to keep all the heat in and my kids can't poke holes in it just by poking at it (which they did all the time with the thinner one last year). The tape actually sticks as well, I didn't have to go buy double-sided tape separately. I will be buying extra since I have TALL windows and this just comes a little shy of the length of my windows, but honestly that's my own fault for not measuring my windows.This product is great!

Product is very good if you ignore instructions.First Clean the surface where tap will go using isopropyl alcohol and then make sure it is dry.If surface is cold warm using heat gun.Once surface is dry and warm apply tape and remove protection cover from top of window tape.Then follow the instructions that came with the product.
