Keeps the cold out
Works great to keep the cold out. Went up easily with one person. This was a concern but worked great. Easily trimmed off excess with scissors. Fits the entire slider doors perfectly. I am pleased and will buy again next year when needed

Amazing product
It seemed thin, but I purchased an air conditioner, and air comes through the vents. I used this and all drafts are gone, keeping them behind the plastic. A great product indeed, east to install. This is an affordable and effective way to improve window insulation during the winter. The kit includes four clear sheets of shrink film, double-sided tape, and easy-to-follow instructions. It helps reduce drafts and increase warmth by sealing gaps around windows. The application process is simple, using a hairdryer to shrink the film tightly. However, it's a temporary solution, and the film may not be as durable as more permanent insulation options. Overall, it's a cost-effective and quick solution for improving window energy efficiency.

Does more than I expected
This works well fire what i use it for... keeping those dang Asian Lady beetles out. I was so focused on that and dry they're real purpose, dealing the windows to kill drafts. I spent less on oil because the heat stayed in. That's a real plus with the price of oil these days. Measure right, cut the sheets, and apply the tape. Easy peezy.

It worked well - clean area first!
The foremost reason for this: insulation. I had this on my window for almost a year and it kept the weeping water on the inside. The install was simple - you put the adhesive tape around the border of the window and then stick the plastic sheet to the tape. The tape adhered well. Highly recommend you clean the area to be used first; dry and make sure no soap or residue is left behind. It looks slightly tacky, but I kept curtains over it. I did my install OVER the blinds to not see it from the outside. The room draft was fixed, but my blinds were unusable haha.

Nice window seal!!!
It works!!! I have a couple windows that don't close properly and would let cold air in. This winter I tried this and it works!!! It's easy to put on. Just take your time. It's almost like working with shrink wrap so don't rush. And if you have a window AC, take it out. Or you'll have to do what I did and do another section around the AC unit. But that's minor. It works. Keeps out the cold air. It's cheaper than replacing windows 😊

Good product, but thicker would be better
Used this product for several years. Mounting and shrinking an easily acquired skill. Thicker for better heat retention would be appreciated.

It was very easy to install. In every other kit i bought, the supplied tape was a pain to use, but in this kit, it was very easy to peel the tape without wrecking it.
