EASY-PEASY HEATING ECONOMY,
This review is from: tesa 05432 Insulating Film for Windows, Transparent 4m x 1.5m (max) (DIY & Tools)
An excellent product, not least because it is easy to use. After some initial experience I was able to install the film as tight as a drum without having to use the hair dryer. This is because the film will lift off the adhesive strip for progressive tightening adjustment. It's not like contact adhesive, where, if you don't put something in exactly the right place, you're stuck with it. You can lift and adjust again and again until the film is invisibly taut.
The lifting and adjusting technique is rather easier if there is a nice wide frame around the glass. So the trick, I've learned, is to fix the adhesive strip close to the glass, so as to leave the maximum width of frame for fingers to grip and pull.
If a window is deeply-recessed and has only a very narrow frame around it, like some of mine, the job's a bit harder, and you could get a few creases. But the hairdryer will take care of moderate creasing.
Best of all is the double-sided adhesive strip. Picking the backing off double-sided tape can be a nightmare--but not with the Tesa stuff. Providing it is firmly thumbed down, a sharp craft knife lifts the backing off like a dream.
Be kind to insects. I sealed up a greenfly in one of my windows. I expect he'll crawl about and crap all over it. I don't blame him; I'd do the same.

Yours seems the most informative review on here, so I hope you can help by answering one question: is the double sided tape provided clear? I'm looking to apply this film to windows with a dark wooden frame, so white tape would be no good! :)

I'm pleased to tell you that the tape is perfectly clear, and suitable for dark wood. I used the Tesa product on a glazed, hardwood door. Of course, where the film adheres to the wood, the surface is very shiny (shinier than the wood itself) but this is the film reflecting light, not the adhesive tape. Your request for more information has prompted me (just now) to take another look at my Tesa-sealed windows. In the kitchen I found the film surfaces to be very dirty-not surprising, perhaps, since they've been in place for almost two years. Before returning to my keyboard, I did a quick experiment, and succeeded in cleaning the surface with a damp tissue.
I have now read the critical review by "Northern Climes" in which he says that the Tesa product has given his windows a 'grey tinge'. I simply do not understand this. Did he seal in some moisture? This might evaporate and condense on the inner surface of the film or on the glass. The Tesa film is totally colourless, and unless you instal it during a chip-pan fire you can expect it to be entirely invisible. As for the tape's adhesion not being as great as the competitive product, perhaps this is what allowed me to make my film really taut, by making lifting and stretching adjustments. See my original review.
Some people are using this product to seal off draughty windows, and there is no doubt it will do so very effectively. But you should understand that if air is coming in from outside you will not achieve the insulation associated with secondary glazing. The pocket of trapped air between the film and the glass must be sealed off from both the air in the room and the outside atmosphere. Only then will the film be warm to the touch, as described by "Northern Climes".
Good luck, Monotone. If your snobby neighbours, with thousands of pounds worth of posh, sealed units, rib you about sticking 'cellophane' on your windows, take pleasure in the fact that a thin, plastic film transmits less [much less] costly heat to the outside world than solid glass.

Thank you for taking the time to not only answer my question, but to also add further valuable information!
Our windows seem well sealed, so it's just a case of using them for their intended purpose as a second layer. They seem exactly what we need to reduce our bills :)

Very handy info. The greenfly comment made me smile! but, it did highlight what can happen, thank you.
