Reflective Window Film Insulation Roll 24 in X 10 Feet, Foil Aluminum Roll Double-Sided Foam Core, Summer Window Heat Blocker for RV/Skylight Windows - Folded Package

Installed this on older drafty windows and noticed an immediate difference. It reflects heat back into the room and noticeably reduces cold air coming through the glass. The material is thicker and more durable than typical plastic window film, and it cuts cleanly with scissors. Installation is straightforward with tape or adhesive strips, and it stays in place once mounted. It does slightly reduce visibility since it is reflective, but that is expected and worth the tradeoff for the insulation benefit. Great option for winter use, apartments, or older homes where replacing windows is not realistic. Solid value for the price and does exactly what it claims.

Absolutely great product. I am ordering more does everything it says it does. We live in Tennessee we did all our windows. We have a cold spell and I cannot believe how much warmer our house has been love this product would recommend it to anyone that is looking for a product to keep the cold air out. Absolutely recommended. also very easy to install very easy to cut. We did six windows and a glass sliding door. this is also not only heat resistant. It is cold resistant we did half of our glass door put my hand on the part that was done. You could not feel cold air coming in felt the other side that we did not do and you could feel how ice cold that glass was. This is so highly recommended. You will not regret this choice.

I used this to insulate an outdoor kitty's house. I like that is a lot thinner than cardboard and all the info I find online says this is warmer than cardboard. I love that it comes with plenty of aluminum tape. The only reason I gave it 4 stars instead of 5 is that unlike the photos in the ad, it comes folded, not rolled and the creases make it more difficult to work with. For reference, I bought the 48 inches by 10 feet.

Used it inside of RV window coverings that I made. Worked perfectly! Was able to cut it all to size. Thin but does the job

Easily cut to fit windows works like a champ has cut our heating bill down tremendously and also helps with the cooling highly recommend recommended have it on all the windows of my RV works great.

Was folded, but no big deal. Rolled it out and let it sit for a day or two, then it was fine. Applied it the water heater, included tape was useful and worked well. Would purchase this item again!

I reordered this because there was a tear in it, and it lost the roll of tape, but nope! They arent actiually adding any tape to the product, they send you velcro sticky dots, that does absolutely nothing for me and the location that I need to put this, but do you know what does? the actual tape shown and listed in this product. By the time I had the product it was too late to make another order, and I had to find something else; so is it worth it: not on your life if you're not providing what I need. Insulation performance is mediocre in cold, but propably more effective in heat (I have used simmilar before, not verified), but it's what I could get to seal a broken basement window for the winter

I've put this over multiple windows that don't get used which felt like heaters all day from mid morning to a bit after after sunset (desert life problems). The difference I felt was immediately noticeable. I ended up finding more spots to use this that I hadn't considered before purchasing and had good success with those as well. It came with both little Velcro pads and the reflective tape. Between all of the insulations I've used a good amount of both and it has all held up great. I really like having the Velcro pads as I have a little inverter nook that I keep covered with this and it allows me to still have easy access to the inverter if I need it (has come in handy twice now). Have more projects in mind and will absolutely be buying more.
