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!

Put these on and seem to help a bit. Although true winter isn't here yet. The only downside it is a huge sheet, they could have cut it down at the factory to make it easier. But not that hard really.

Our problem area was a cluster of three single pane windows in one very large wall frame. The composite frame was too large for one plastic sheet to cover and the indoor window frame faces were on two planes. Fortunately the outdoor frames of the separate windows were all on one plane so two exterior kits were workable. Outdoor temperatures were problematic due to the time of year so, even though I waited until the thermometer said 51 degrees outside to do the installation, I used a double line of tape around the windows to increase the chances of getting good adherence to the wood frame. Plenty of tape is provided in the kit. Installation on the smaller window was a piece of cake. However, the only reason I don't award 5 stars to the product is because the plastic on the very large window has fairly permanent, angled creases (from being folded in the box) which are visible in the right light and inhibit the plastic from unfolding evenly. These creases make it necessary to do lots of repositioning trying to reduce puckering on the uncreased side as one side is effectively gathered up in the creases while the other side is not. Using a hairdryer to shrink the plastic to solve this problem is not recommended as there is a concern that the plastic may shrink too much and come loose, especially when sun can heat and shrink the plastic further. However, because no sun ever hits these windows I used the hairdryer sparingly but the puckers and creases remain. Ultimately, this is a very good product. It continues to hold a cushion of air between the glass and the outdoor temperatures. The puckers and creases are very minor annoyances (and only obvious in the right light) while the problem of cold and water condensation on the inside of the windows is hugely ameliorated. I highly recommend this product for the exterior when interior installation is not possible.

This will be my second winter installing these things. Note there are films you apply to the exterior of the window and films you apply to the exterior. These go on the EXTERIOR. I have small children and don't want them fiddling with the films and i worried about interior films fitting under my Venetian blinds. I prepared for these to be a major pain in the posterior to install and braced myself for hours of the film folding over on itself and working out creases. Boy was I wrong. It actually wasn't all that bad. I covered nine windows in about an hour or so. If there is a glaring crease, it is easy enough to pull the film off of the tape and straighten it out. They held up from early November to May with no punctures or tears. It has the pliability of saran wrap (it stretches) but is not adhesive so it doesn't get stuck to itself. You are not supposed to install them if it is below a certain temperature outside (I think 50 F), so don't procrastinate. I don't know what happens if it's too cold--I'm guessing the adhesive doesn't adhere as well. They tear off in one easy piece in when you are ready to take them down but the double-sided tape will stay attached to your house. I should have scraped it off but let it stay there so I can't say how hard it is to remove. My gas bill dropped in half but I don't know how much to attribute to these alone because I added these, along with a programmable thermostat and power outlet insulators, at the same time.

This product is relatively easy to install, but you need two people to manage the large sheets. It went up easily. The only concern I have is the film is thin and rather flimsy and I question how it will hold up over the winter. Time will tell. if It stays intact I will be very satisfied as I put it up mainly to keep the spring pollen from coating everything on my porch. The extra protection from wind and rain are an added bonus.

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.

These kept our living room toasty warm when put over the very old windows I thought had to be replaced.

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.

Such a simple, yet effective, solution to draughty windows. Very easy to fit. Had air leaking through large front window causing living room to be cold. Instantly fixed on attaching this. Very impressed and £100s cheaper than buying a new windows

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!

I had the indoor/internal version of this product which works very well in eleminating condensation of my aluminium windows. There are some window frames that are not working for internal application (ie, sliding windows). I bought this outdoor version and applied it on the external side of the window frame. Unfortunately condensation still occurs. The film unable to keep the glass pane temperature warm enough to prevent condensation. On this scenario, I found bubble wrap applied on the internal side works better.
