Frost King Window Heavy Duty Shrink Window Insulation Kit 42-Inch/62-Inch (Pack of 3)

I’d buy this product again instead of one of the pricier alternatives, but I’d still wish the tape would hold better.Five stars for an imperfect product because it was only fifteen bucks and other stuff costs a lot more but doesn’t seem appreciably better. If there was an alternative product with the perfect tape (and maybe instructions for what temperature settings on the heat gun), I might opt for that. FTTB, I’ll be happy to use this product again next Winter.What I’ve learned is:- Don’t over-stretch the material with the heat gun. It’ll pull the tape off the edges.- Favor rectangular shapes. Irregular shapes also led, in my experience, to the material pulling off.

I've installed a lot of window insulation like this over the years. This brand is just as easy to install as the other thinner brands, and I think it's going to insulate a little better. It did take a bit more time to heat and shrink with the hair dryer, but I'm sure that's just because of its thickness. The two sided tape worked as expected. Just make sure your window frames are clean, so the tape has a solid surface to adhere to. The three big sheets that come in the box will give us enough to do the windows again next year.Not long after installation, one of our cats put a small puncture in the film with it's claw. However, because it's a bit more thicker, I was able to easily patch it up with a small piece of clear cellophane tape. You can not tell it's been patched unless you're standing up against the window.

Not the best out there, I like to use the heavier thickness as we live in -30c to -40C temps.Works good enough, would love a 65 inch width. Tape was easy to use.

This is easy to use and unfold and the double sided tape works very well I was really impressed

It was a little awkward to install but it shrunk & is staying in place so far.
