tesa 05432-00000-01 4 x 1.5m Thermo Cover Window Insulating Film - Clear

Take your time to apply and it's great stuff.

Really effective on our poorly fitted upvc windows that leak air because they do not shut properly.
I saw other reviews saying it pulls off the plastic windows but I never had any problems with the supplied double sided tape.
After applying the tape, before you peel the other side off just make sure you go round it with a teaspoon and really press it on. I also warmed up the plastic with a hairdryer on low setting to get rid any water from cleaning around each window with bleach before fitting.
Preparation is the key like with many things. Take your time getting the surface ready and everything else follows suit.
DO NOT put your cut piece of film down on the floor or a bed because every little bit of dust will stick to it as I found out with the first bit I put up lol. Peel the double sided tape off then cut the film and stick it straight on.
Once on go around again with the teaspoon and you will hear it clicking, it is then stuck on properly.
Again with other reviews I saw pictures that clearly showed people using too much heat/or getting too close to the film, there is no need. Low speed and heat and just woft it over the film from about 10 inches away like you're spraying a car and it will shrink perfectly.
Once you tap it and it sounds like a drum with no warping or wrinkles you're done.

It made a huge difference in our house. We rent so new windows are not an option and the landlord won't but new windows. No drafts coming down the stairs and the upstairs stays hotter for longer now.
Very happy. Cheers.Read full review

Does what it says on the tin!

This has made such a difference to our draughty old barn of a house. Ok its not triple glazing, but it doesa very good job of keeping out the cold and stopping the condensation. Our bedroom is a few degrees warmer at last.
I found the product easy to use, and I'm not the most dextrous person in the world. Actually quite satisying to use the hairdryer to tighten the film for a good fit. Would wholly reccomend!Read full review

It works!

Just about every morning, in Winter, my Georgian single glazed bedroom windows were dripping with condensation. After fitting this film to all but one window (the only one that opens), there is still a VERY small amount of condensation, but now it's trapped between the glass and the film. No 100% perfect but much better than before. I haven't noticed a huge difference in the room temperature, but it wasn't a cold room before.Read full review

Amazing value for money

Performs exactly as describes. Did one of a pair of single glazing sash cord windows and it was a very cold night. One without the Tesamol covered in condensation, Tesamol window clear. Great for reducing draughts in the casement windows. Also works on the failed double glazing units by stopping the draught round the seals.
Take care cutting as the film rips easily.Read full review

does the job

really easy to fit and really does keep the glass from steaming up.

over rated over priced

no instructions provided. The online videos by the manufacturer and the photos are very deseptive. Managed to install them somehow but was very disappointed with the results.
