tesamoll Thermo Cover Window Insulating Film - Transparent Insulating Foil for Thermal Insulation of Windows - Includes Double Sided Tape for Easy Installation - 1.7 m x 1.5 m

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.

Yes, I know I gave this product 4 stars but that is because anyone with a brain ignores 5-star reviews. The real opinions can be found under 4 stars.I have used Tesa products before, so buying this one was a no-brainer. I have a draughty house and I was fed up with ignoring them.It does not matter if does not look nice it is purely a temporary measure and will come down in the Spring.As soon as I fitted this to a bay and bathroom windows I noticed the immediate change in the room temperature. And I kicked myself for not doing this last year!My tips for fitting the film is to allow plenty of time, especially if you have not done this before. The surfaces the tape is sticking to have to be extremely clean. No flaky paint, stains, lumps etc. I used a regular surface cleaner and dried the surfaces afterwards. I then used isopropanol and dried that too. Do not touch the surface with your fingers again. I started by taping the corners first, making sure I overlapped the tape a few millimetres. Tape it, remove the top cover then continue taping. Don't tape everything first then remove the top layer, there are no shortcuts. That's why I said give yourself plenty of time. Once you have done the corners and taped the gaps between them cut the film with at least 5cm extra all around. Using both hands gently stretch out the top of the film with both hands as you approach the window. Keeping it taught press one corner then the other corner while still taught and smooth down the rest of the film on the top of the window. Always taking care not to attach the rest of the film anywhere else. If you do just gently rove the part that is stuck. Now again with both hands hold either side of the film and again as taught as possible slowly work your way down the frame, sticking as you go. Don't over-stretch, just enough so there is no sagging. Again once at the bottom press in one corner then the next as you did at the top. Firmly press the film onto the tape around the window.Get yourself a sharp knife if you are working in a recess or sharp scissors for the outside of the frame and trim off the excess plastic.Now the fun part. Using a hairdryer, any one will do as long as it has a hot setting. Switch it on and depending on how hot the dryer gets determines the distance away from the film. Too close and you puncture the plastic and you are back to square one. Too far away and the film will not shrink. Once you find the sweet spot where the wrinkles disappear then just move the dryer back and forth across the window and watch the wrinkles vanish. You should be left with a window just as it was before you did anything and without any draughts. If not as it looks awful but you have no draughts then remember it is only temporary.I highly recommend this product and I hope this review helped.

I put fitting this off for weeks as thought it would be fiddly and I’d damage the sheeting.I WAS SO WRONG.I’m just having a celebration cuppa as fitted to two ft square single glazed windows.I never received English written instructions but found a short video on the brand website which was more than enough.Tips I can give are clean the windows and paintwork thoroughly and let it dry. We don’t realise how bad our painted windows are until we get up close. With hindsight I would have scrubbed mine and likely sanded and repainted mine a few days before but hey ho.Also make sure you’ve got good safe access, sills are cleared and curtains are held back etc.The tape is almost invisible once fitted if laid completely flat, I used a cloth to get mine totally adhered (with the backing paper still in place) before I fitted the film. The tape allowed me a couple of attempts to get it perfect (ish) before I flattened firmly. I thought the backing paper would be fiddly to remove but as long as the tape is pressed down, it’s very easy to pick the first bit off with your fingernail and enjoy the pleasure of peeling the entire backing off in one strip. The tape leaves an almost fine glue like strip once the backing is removed, so you can overlap if done carefully.The film initially feels quite fine but cuts with ease. I left an overlap incase I misplaced it… which of course I did! I can happily report the I repositioned the film many times without stretching or ripping. Once done I pressed it over with my trusted clean cloth.I thought the hairdryer bit would be tiresome but mine went drum tight in a few seconds as the windows were so small.I trimmed my off with a sharp razor style blade but was a little heavy handed.The finished product was almost invisible, my heavy handed razor lines showed up the most.I’m really pleased and will update longevity when I remember.I’m off to make another cuppa as it’s gone cold… then I’m going to do my final bigger window ;-DQuick update, my first window is looking good after 15 minutes but my second window is steaming up a little . Access to the 2nd window was harder so I was really close to it and likely breathed too much so before I place the film on the final window, I’ll give the glass a final dry buff and hold my breathe a little maybe.My apologies for the long ramble but hoping it helps if you’re feeling as tentative as I was.
