Tesa Transparent Insulation Film for Windows - 4m x 1.5m

I only put it on a few days ago on a very large stain glass single glazed window on the stairs that was just haemorrhaging warm air out if the house. I wanted something that was easily removable just in case it didn't work with the textured glass. I needn't have worried. It went on wonderfully and you only notice the film when you run your hand over the glass. Even though its only been on a few days I can already notice the cold pocket of air from the stairs is gone. The true test will be when the weather gets much colder. I would however remove half a star for 2 things. It's quite difficult to get a single layer of the film separated. On the first panel I had actually put a double layer on without noticing so when I trimmed it from the rest of the sheet I actually ended up wasting another window square's worth. The second reason for removing half a star is how fiddly it is to put on. Maybe because I was covering 6 panes rather than 1 large one it was more difficult. Cutting the film to size is quite hard if you want it for smaller window. The tape is super sticky so it's very unforgiving if you don't get it spot on first time. It's also very easy to melt a hole in the film with the hair dryer that's needed but you just need to be careful. Saying that I'd still recommend it to anyone. A cheap way to keep in a bit of heat. Plus a little tip, warm the window with the hair dryer before putting on the tape. Makes it a lot more stable.

Les vitres ne s'embuent plus en hiver. Assez facile à utiliser, mais il faut être très prudent et délicat lors de la pose et de la répartition du film, et appliquer le ruban adhésif à 1,5-2 cm du bord intérieur du cadre.

I live in a very old rental house, where all the smaller windows are singles glass, of course the owner is not interested in changing the windows or doing anything. I suffered with the windows from September until March, almost every day there very humid with a lot of condensation, and cold. I got the product and thought maybe it can be help me. It dis not help me it changed everything, now there is condensation in the windows, not even when im cooking or taking a bath, which is incredible. I would recommend anyone, it is true that it can be complicated to install, but once you do it, it is incredible if you have any window that is bad considered using this product!

This is rubish. Very unsatisfied. The double sided tape dost stick at tall and peeling the top is impossible. Don’t waste your money

Helpful to be two people installing.
