Muy funcional para la temporada de frío, se pone muy fácil

I'm not sure I was expecting much, and after reading reviews, was sure the plastic would be clingy and very hard to get open and install. Not true at all! The plastic is amazingly clear and you'll never know once it's up, you have anything to the window. My large picture window in my living room, leaked air so badly, I could sit on the couch and feel the air pouring over me, even with double lined thermal drapes! This plastic opened easily, and was easy to stretch. The tape looked very flimsy and I did not expect it to hold, but it did and if you put the plastic on it, it's easy to remove and stick again. I didn't think that would actually work, but it did. I pulled it as tight as I could and then took the blow dryer to it. At first, that didn't work well, until I realized, you have to set the drying almost directly on the plastic and then it will shrink and tighten the plastic. Plastic sticks well and doesn't come undone. The amount of cold air it has stopped is simply amazing! It's warm and cozy. I made sure the window was super clean to begin with, and the wood I was sticking the tape to, had no oils from polish on it. My window had a wooden window sill, so I took the plastic over the sill and taped it underneath the wood, and that provided even more security for sticking. I will definitely be ordering more for other windows. Don't be afraid of hanging this yourself, as you'll be quite surprised at how well it works!

Me ayudó mucho a que no entre la corriente de aire frío, mi casa ya no es un congelador.La cinta que trae no me sirvió. Termine pegandola con cinta doble cara que ya tenía en casa para una ventana y el resto con cinta canela. De ahí en fuera estoy muy contenta con el resultado.

Easy to fit. Makes a difference in winter.

The film is very thin and can easily get pierced by sharp object if not careful. Has to be installed at least an inch away from glass pane to be effective.
