tesa 05432 Insulating Film for Windows, Transparent 4m x 1.5m (max)

Pros: good quality foil and double sided tape. Sufficient amount of tape. Small cardboard packaging. Good easy instructions. Strong hold on the tape even tho I reglued one window sheet when learning. Very good transparency. Doesnt look like theres foil unless you touch it. And most of all does insulate. When I press it to feel the window glass underneath, the glass is very cold but the foil pleasant lukewarm. Attached yesterday on three windows and kitchen door. No condensation between the foil and the glass. I mounted it on double glazed pvc windows in the study, living room and kitchen and on pvc kitchen door as these are the rooms i spend most of my time working from home and bedroom i only use in the evening. Although the room temp in those rooms and the two bedrooms is the same, the quality of that cold is different. In the bedrooms its more chilly on the skin and in the insulated ones it's still pleasant despite being 16c only. I'm trying to postpone having to put heating on as it's just me in a three bedroom flat of energy efficiency E only and that will definitely help.Cons: only that it might require some manual skills and patience. It's not for people who are not very technical or manual unless you won't mind some excess foil if not tensed enough. I had manual jobs before so ended up invisible but it might not be the case with everyone.Process: the manual says leave 5cm spare around the tape and when taping do the top and the sides, then bottom. I wanted to cover as many windows as possible with one sheet so i kept less than 5cm. Turned out still good and did three rooms in full with still some bits left. Also i found it easier to tense and avoid excess wrinkling and flapping about being visible on the window by doing too, then bottom, then readjusting top, then doing one side at a time to tense it more. Then you heat the tape and run your fingertips alongside to smooth any wrinkles on tape or bubbles. Also heating (not too close not to melt) made the foil adjust and tense in the corners so it's tense as s string and straight like glass. See pictures.Advice: the heating doesn't make it heat shrink to glass. It smooths out excess and most of all helps the adhesive. It's not meant to stick to glass but create air chamber between just like you have between two sheets of glass in double glazed. So on singke glazed old windows you'll make them double glazed. Which is fab. If you have wooden frames, I would recommend maybe sanding or varnishing smooth first. I don't know how the tape would stick to rough wood. I used for smooth frame. Take your time. Don't rush. Plan by looking back first how you'll do it in terms of where to put tape. I saw reviews of people wanting to use around the handles and on the far outside part of frame. This is not for that. If you need to insulate the frame, use self adhevise rubber seals for doors and windows or poll filla foam. This product doesnt insulate window frames, it's supposed to insulate the glass and also stop any draft from places where the glass goes into the frame, not where the frame goes into the wall. Think of it as another sheet of glass and check where original glass goea into the window frame. This is how you'll know where to put the tape and mount it all.Pictures: attaching from evening of mounting and the next rainy day. Was going to wash the outside of windows first to test extendable pole i bought, so that it would show full transparency but it's a rainy weekend.

I bought this as the inside of my windows would be dripping wet in the morning. As I keep my desk, computer and console by the window, keeping them safe during the winter months was top priority.As the product states, it's designed to insulate your room and I've definitely noticed my room retaining some much needed warmth. The condensation has been reduced significantly. I was pretty amazed that a simple (perhaps slightly overpriced) thin sheet of plastic could make such a difference! The film was very easy to cut to size, it's recommended that you leave a 5cm overlap when attaching it to your windows. Blow-dry your sheet to make it nice and taut and you're good to go.Now onto the negatives: I found the included double-sided sticky tape to be pretty useless on my plastic window frame. (Your mileage may vary) Despite cleaning it thoroughly, the tape just wouldn't adhere very well, especially at the corners, which led to gaps in the insulating sheet. To remedy this I used I few tiny drops of super glue on the edges of my window frame and now it's airtight. I also noticed a few wrinkles after blow-drying the sheet, but nothing major.

Having moved home last year, we discovered our new home has a condensation problem. Our first floor windows get horrendous condensation during colder periods, particularly our bedroom.I have been trying various fixes and hence found this little gem.So, it won't solve a damp issue, so if you condensation, like mine, has a cause known or unknown, it won't stop it altogether. It has massively reduced the amount of condensation we get though. You can see from my photos the middle window hasn't had this film applied and the windows to either side has. I'd say it reduces condensation on the window by about 80%So, if your condensation is simply caused by hot air hitting the cold window pane, this is a crazy cheap solution that should fix your problem totally!I initially made the mistake of thinking it blowdrys on the glass...it doesn't. It creates an extra air pocket and another layer of insulation.It goes on completely clear once you warm it and all the rinkles magically disappear. Just make sure you haven't got any hair or dust on the inside before putting it up... I didn't think about it and now have a permanent clump of cat hair in the window.I did it all by myself but a 2nd person would allow a nicer finish.Brilliant product. If your still reading and looking for something to help your condensation but not sure if this is a real solution , this is worth buying, it is!.

Just have a brand new patio window installed so perfect opportunity to try out this insulation method. What a waste of time and wrangling with the plastic sheet on such a large pane of glass. Applied to one door only so could make a comparison. It made absolutely no difference whatsoever to the cold coming through or the condensation which collects at the bottom. I don't know whether the plastic sheet needs to be thicker in order to be efficient, this is as thin clingfilm, don't waste your money, emperors new plastic. Also every tiny bit of fluff and dust sticks to the plastic so it's a v v v frustrating job to get it on the window clean. you clean the window first but the plastic acts like a dust magnet and attracts everything to the glass you've just cleaned and the plastic sheet. don't waste your time and energy. disappointing. Tried to give zero stars but of course you can't.

It's quite fiddly when doing it by yourself, but immediately noticed a difference with it up.
