Duck 1163221 Indoor Shrink Film Insulation Kit Insultation, Clear, 10 Windows

This is my first time using something like this but this window sealing kit has been great at sealing out the cold from our house! We have an older 70's house that still has the original windows (single-double pane, no insulation). Which is a killer on our heating bill here in Canada until we can switch out all the windows for newer ones. This sealing kit was super easy to install and is barely noticeable (the only noticeable part being on the window frame if you squint). Drastically could feel and see the difference it made to sealing in our heat! Even going as far as keeping our house from overheating too badly from the sun during hotter temperatures. Overall, would recommend!

No complaints with the installation, some of my windows are sliding sash windows so it was a bit fiddly to install but that's not the fault of the product. Pretty forgiving of bad workmanship as a blow with the hairdryer takes out the creases and gives a great finish. Definitely notice the difference in terms of insulation and sound proofing. Worth doing if you can't fit double glazing for any reason.

I have 11 single pane windows which as well as letting out heat , have a lot of condensation on them in the morning . I decided window insulation would probably be helpful . I was a bit dubious of which brand to try , however I settled on duck . The first window I tried was easy to do , the tape stuck well and was easy to place , however I hadn’t checked the length of my windows properly and the film was too short 😡 I didn’t want to bother doing it again so I added a bit to the bottom 🤣 probably not ideal but still does the job . For the remaining windows I put the film on sideways which was a bit more fiddly but still easy to do . The shrinkage with the hairdryer is perfect , although be careful as I got to close to one window and burnt a hole in the film. Even with my two mishaps (my fault not the fault of the product ) it is doing , what I hoped it would . The film has been up two weeks , has reduced condensation and increased the warmth in the room . Overall easy to place ( really easy if you’re windows are less than 5ft) Photo shows one window with the film on compared with the adjacent window without it .

The best liner that I have installed. The lining is thick and sturdy so it doesn't tear easily. The adhesive tape is a bit tricky to separate from the nonstick strip but once separated it was very easy to install. (Recommend 2 adults to install so that you can affix evenly). Once sealed, I used a hairdryer to stretch and then cut off the extra film. Great seal which will save us a lot in hesting.

Este producto sirve para las corrientes de aire, no para el frío intenso. Te ayuda a que no haya una corriente en el cuarto que pasa de una ventana a otra cuando este cerrada, bloquea las corrientes, pero no el frío intenso ya que requiere de aislamientos especiales y con un costo mayor. Debemos entender para que sirve este producto. A mi me funciono.
