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

When I bought this I didn't expect it to be as good as it was. I'm happy to say it has actually surpassed my expectations, but that's not to say there aren't some negatives about it. Firstly, I bought this because my rented house has old double-glazed windows that basically aren't double glazed. Despite running a dehumidifier to the point where the air was as dry as a desert, and the wife and I would wake up feeling hungover we were so dried out during the night, the windows were still covered in condensation. And with condensation comes black mould. So I bought this. To be honest I felt cheated when I got it. It is just a sheet of thin plastic and some double sided tape. So not worth the money, right? And then there was the putting it up. Having to find floorspace enough to cut a window shaped size, while the cat bounds around on her new crunchy crispy playground that you (obviously) have bought just for her was a pain in behi d to say the least. Depending on how big your window(s) is/are you're probably going to need a hand putting it up. Sometimes the plastic sheet hits the exposed tape before it's meant to causing rucks etc. Most of these you can sort out with a hairdryer, but some you can't. There isn't a worse feeling than fecking around with all this only to find a huge crease along your window pane that won't go away. Finally, it's up. You take the hairdryer to it and eventually you cant even see that it's there. Not only has it stopped ANY condensation forming on my windows, it has also made my house much warmer. Win! I've actually placed it to just above the window handle meaning I can still open and close my windows, and therefore I leave it on during summer. I've had the current set on for about a year. Just beware, you forget it's there. So you go to peek out the window at something going on outside only to bump your face against the new invisible forcefield before the glass. Doesn't hurt, but can break the sheeting. Overall then this is the most effective, simple, yet fiddly solution I can imagine. For the results I've had I'd say this is as cheap as chips. However, if I'm basing it on what you're actually paying for then I'd say this is overpriced. But since it's not going to break the bank, if in doubt I'd say go for it. I will definitely get it again if needed.

The film works. No doubt about it. Keeps he room warmer and no water on the windows. However, You're going to have to keep readjusting it as the tape is not strong enough. This creates air pockets in between the film and the window creating folds and creases. Overall. OK solution until windows are eventually replaced.

i was a little apprehensive about putting this up .... my main reason for doing so is my home is listed and has single glazing and i livterally am across the road from the sea so condensation is a nightmare. the impact this has had is immediate. condensation reduced to an absolut minimum rather than running down the window pain ... as for visibility, it is not an exaggeration to say the the clarity is such that i genuinely do not know its up. i would take a photo but honestly, theres no point as you would see anything! remarkable and actually fun to put up because when you run the hair dryer over it you see all the wrinkle disappear. (i know right? little things please little minds). is there a rise in the warmth of the room is more hard to tell as i have 15 ft high ceilings ... lets just say i don't notice it being any colder.

Absolute waste of time. Wouldn’t stick, all creased. Would give this 0 stars if I could

The product would probably be great on windows where you have a lot of flat space round the window to apply the adhesive tape, but on awkward shaped windows like mine it's awkward. I added these to my victorian sash windows and had to tape onto corners because of the way the windows are made. First day or so you couldn't see the film and could definitely feel insulation improvement. Much warmer in the room. But after several more days the plastic shrunk and took the tape off the tight edges, losing the vacuum and crinkling the shrinkwrap. It does say in the instructions you need a decent space between tape and glazing though. And I did buy knowing this.

Used in a box room thats North facing and seafacing with a wooden window frame and lots of cold,damp and windy weather to deal with. Had a mold problem, not really bad, just in the corner above an air vent that creeps along the ceiling above the window frame and along the bottom of the wooden window frame and cill, not the worst but looked grotty and needed addressing, all the mould sprays etc performed a very temporary fix and I thought this was worth a go, measured the window, cut the film and sticky strips, the film is completely clear (so you can't see it from outside) then followed the instructions, which were straightforward. This was a complete success, the room is noticeablely warmer, mold has stopped completely, it just didn't come back and we've seen some seriously bad weather this year. I keep going into the room and checking but it's bone dry and no mould. I've been able to completely clean and repaint everything and it's all stayed mould free. For the price and the ease of installation, it's very very impressive.

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 had a drafty livingroom widow behind the sofa, so thought I'd give this a go !! Works very well no draft whatsoever and no condensation. But I did find the sticky tape was utterly useless, so I used double sided carpet tape from poundand !!! Cut it ti size and works a treat !!!! Although I did think this item is over priced for a sheet off thin plastic and useless tape, it's done the job, but wouldn't buy again because of the price.
