3M Outdoor Window Insulation Kit, Clear Window Film for Heat and Cold, 5.16 ft. x 7 ft., Covers Two 3 ft. x 5 ft. Windows

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.

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!

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!
