Duck 286218 Extra Large Patio Door Shrink Film Window insulation kit, 1, Crystal Clear

I’ve used this kit for the last few years to seal my windows in my Motorhome for the winter. The adhesive is very sticky. The product works very well in keeping the heat in and the elements out. Ordering more for next winter.

Amazing what you get for the amount you pay. It's not perfect but it definitely helps a lot to prevent the cold air from coming in. It's also pretty easy to install and the adhesive works well. You might need and extra person to help since it's so big, and if you want to get it perfectly straight the second person can really help.

Size was more then enough, not very thick but was very effective. Strength was good. Insulation was very effective and no hot air hot in. Peeling is easy as well

I am very pleased with this product. I admit to procrastinating buying it until it was already cold an average of 40F or lower outside, and so I was worried that it would not stick well. Our house is built out of cinder blocks and has absolutely no insulation. We have large VERY drafty windows that are all irregular sizes. I bought two packs of this and was able to cover two large windows in the living room (~5'x4' and 6'x5') and one 4'x4' bedroom window, before I ran out of double sided tape. However, there was still plenty of film left so I used gorilla tape and was able to cover another 4'x5' window and another 4'x4' window. I had large enough pieces left over that I could have covered more windows but we didn't need it. It has made a huge difference in the temperature of the house already. It was necessary to leave some flexibility to cover the window crank handles without seeming like it would poke a hole in the film so I did not smooth the film with a blow dryer as directed. It is still very clear and it was easy to apply smoothly over the top half of the windows. I did not peel pack all the tape until I was ready to apply the film. It has been a week of subfreezing temperatures now and the film has not come off. It did not seem like it was sticking at first but after taking off the back, both sides of the tape were more flexible and stuck to the uneven cinder block surface and have stayed. I heated up the walls with a space heater before applying the tape in the living room. I just set the space heater to blow on the wall for about 5 minutes beforehand. This may have helped adhesion, though it did not warm the walls very much. The gorilla tape may be a horrible idea; we will see in the spring. So, I don't recommend that to anyone else right now. I recommend that you buy an extra roll of window tape if you plan to use all of the film that comes in one or more of these packages.

Very pleased with how well this stayed attached to my windows all winter and came off with minimal effort and less mess on my windows frames. I did go the extra mile to clean all of the windows before I applied this. I made sure to clean the window frames throughly before applying and had no problems removing the tape at the end of the season.

The first time I installed this I put it on the window frame, and while that definitely helped with the cold air from the 4 large old windows along the front of our home, I could still feel a draft. I soon determined that was because the "frame" was an old metal decorative frame, not what one would traditionally be thought I'd as a window frame, and not something I could easily replace or seal. So, I removed the plastic and redid it (with new plastic as I needed it to be wider). It was a little more difficult to get it tight enough that heat application would make it pretty much invisible again, with just a little more effort than the first time around, it came out perfect. This makes a big difference in the warmth of our living room. We have an old home with old single pane windows, so this solution is not 100% blocking. You can still feel that the plastic is cold to the touch, but there are zero drafts. Adding pleated shades (thermal blackout curtains would work too) is the final piece that keeps those ancient windows from driving up our winter heating costs. These were easy to install, just follow the directions and they go on just as stated. The only mistake I made was not pulling the plastic tight enough on the first window. I was concerned about tearing the plastic, but I was worrying for nothing. I pulled it plenty tight on the next 3 windows and there little to no wrinkles. Once heat was applied it tightened the rest of the way to become essentially invisible. I would highly recommend this product.

It doesn’t stick as well as I was hoping, but overall it is a decent product.

The product arrived earlier than expected and does the job. A bit fiddly so make sure you read instructions and view videos before you start.

Super clear finish. Went on as well as these things can. Does the job, no air coming through and it looks like it’s not even there. And it’s cheap so just buy it.

Fácil instalación y cumple expectativas!

Super Qualität, super Preis, schnelle Lieferung, was will ich mehr!

Size was sufficient so a beginner like me was able to cut it up easily. Shrinks really well so adding allowance was fine. House temp improved and winter westher is now bearable (Sydney)
