2170W-6 Outside Window Insulator Kit

Oct 2019: Purchased this product to cover large screens for older, larger condo insulated windows (30" x 50"). Was a little surprised that these were not heat the shrink type that I've used before for interiors. But the product was easy to install (took me about 15 minutes per screen), was easily able to stretch out wrinkles, and no problems unfolding / peeling the plastic open. There was actually enough double sided tape for 3 of my windows, plastic covered two. I've got some larger windows still to do, had to buy one pack for each of those, using the plastic sideways.I did my best to secure the tape to window (pressed around the screen frame with my thumb several times) and similarly the plastic once it was affixed to the tape. If it holds up, should do a good job creating a second vapor barrier and cutting down on drafts.May 2020: Removed the plastic this afternoon. First, all six plastic sheets were intact after a New England winter. Second, plastic removal was beyond simple - the plastic peeled away from the tape easily. The tape needed a little encouragement but by and large came off the aluminum frame in one piece and with no sticky residue. I'm a little shocked at how much of a non-issue removal was. I'm a fan for life!

I wasn't sure about this as the tape didn't seem to be that sticky but to my surprise I put5 this up and a week later we had gale force winds and it did not come lose. I would of like the plastic to be a little heavier but it worked for what I needed.

I’ve been using this product for many years. This time they sent tape with the sticky side out. It must have been put on the roll backwards. I have never in 20 years had such a difficult time getting the tape to stick so I could reposition the plastic to get the wrinkles out. I had to go find old tape rolls left overs from several years ago and use them to get it to work. Very disappointed. Quality control issue…I don’t think the plastic will stay on thru the winter. We’ll have to see.

We have always lived in older apartments that don't have great insulation and this is a lifesaver. It truly reduces your heating bill by at least 15% and makes the space feel much more comfortable. So I highly recommend this for anyone with drafty windows.Furthermore, I recommend 3M as they have the best ones in the market, we have tried them all! My family and I are not the types to care much about brands, typically we find no-name products to be just as good, however, in this instance that is not the case at all. For once, they have the best glue/tape, all other brands are harder to install because their tape is just too weak. Plus, after a few weeks we find other brands need to be resealed and checked for openings (more often if it is a windy winter). Last, they look the most clear and are the less noticeable of all of them. So pay the few extra bucks, it is totally worth it! And Amazon does have the best prices for this compare to other stores.

As stated in other reviews, the tape is crap. Up just one day and blown off... granted it was a mofo of a wind storm, but still 'specially formulated outdoor tape'. I'm going to try again with the 3M double sided mounting tape as I've had good success with that in the past for other applications.*Update... so the 3m Mounting tape sucks... it's not meant for this.. while I've had great experience with the 3m mounting tape in the past, it doesn't hold this in the least. I'm going to have to just double tape this with the intended tape and retry.

I purchased 6 of these kits to cover all the windows in my home. These are the exact same kits I used last year with excellent results.This year, I applied the product on a warm CA day (72 degrees F). They went on easily, like last year. Unfortunately, every single window covering pulled off within 24 hours. The adhesive tape was a complete failure. No rain, no drastic weather changes, only product failure to blame. I ended up removing them all and throwing them away.Perhaps they changed the adhesive? I've always had good luck with 3M products before, but this was a complete waste of money. Never again. Beware.

I installed this window insulation kit in just a short time, and the instructions were easy to follow. The film went on smoothly and became nearly invisible after shrinking it with a hair dryer. It gave the windows a clean appearance and was a practical addition for improving insulation during colder weather.

This film and the included tape have lasted over a year now of continuous outdoor use. I taped it to the removable screens of my 90 year old leaky windows and they stay dry .. you also can't tell it is just cheap film..

I applied it indoors, although it states "Outdoor use only". Fitting was easier than expected. The double sided tape worked perfectly. I was worried about the initial wrinkly look but when I applied the heater it looked clear like glass. I first tried a hair drier but found that a fan heater on 1 kw worked perfectly and easily. You cannot tell the window is insulated. The cold downdraught from the window has stopped. Fantastic value. Highly recommended.

Managed to fit the 3m to my exterior windows (as supposed to be for) ok, however after a few cold nights it is starting to mis shape & now looks awful. Worked well at the beginning. I would try the d-c-fix window film as that make is great. Made in Europe too.

facile a poser et bonne tenue a l'extérieur ; hélas beaucoup trop de condensation.

L’articolo è di buona qualità. Si tratta di un rotolo di nastro biadesivo e un telo trasparente (tipo pellicola trasparente da cucina ma molto più resistente).L’ho installato su una vecchia finestra con vetro singolo e infissi di legno, sia all’esterno che all’interno, creando due camere di isolamento extra (per il lato interno ho dovuto comprare un nuovo rotolino di biadesivo, di un’altra marca ma sostanzialmente identico).Considerando la semplicità e economicità dell’intervento, la differenza è incredibile. La temperatura dell’aria vicinino alla finestra é aumentata di 2-3 gradi, e gli spifferi di aria gelida sono meno percettibili.Ovviamente l’aspetto estetico ne risente. Per noi non è un problema perché si tratta di una finestra che comunque non apriamo mai e ha sempre le tendine chiuse.Ottimo rapporto qualità/prezzo!

Worked as instructed as best I was able to get it straight. Mine came as expected, I wasn't always neat but when I was it worked as intended. No complaints. Prevents drafts and heat loss. Didn't think it could, but it did.
