FONUNO Bubble Insulation Sheet, Reflective Insulation Roll, 23.6IN X 10FT | Double Side Aluminum Foil Bubble Shield Aluminum Foil Thermal Insulation Radiant Barrier for Windows, RV, Roof, Garage Door

This is a great product! I’ve tried everything to keep our back room cool during the summer months and nothing has worked until I saw this product. I received them today and placed them on the bedroom window, which gets direct sun throughout the day, and the room has kept cool. I highly recommend this product. Great price and easy to install

This is great for putting over windows to keep heat out! We placed them over all of our windows. Its dependable and has lowered our electricity bill. Its doing it job and it can be cut easily to fit. Its not blinding reflective but it does reflect light

This sheet is fantastic. My bathroom window gets absolutely blasted by afternoon sunlight and it's unbearably hot in there during the summer. I just cut this to size, doubled it up and added it to my window and the difference in temp is astonishing. The floor of my bathroom has actually been cool under my feet today. Can't recommended this enough!!

I was skeptical but I got it anyway. It did the job. I had to block the sun from coming in the window so my air conditioner didn't have to overwork. My bedroom is now cool at night & I can sleep peacefully.

So I bought this for my metal screen door because I don’t like the heat or dirty air that comes through it but at the same time I wanna put a box fan strapped to two air filters (one 8 Merv electric static aluminum filter set up against the door and one 13 Merv filter that’s actually taped to the box fan itself right up against the 8 Merv) to pull clean air through (and help reflect some of the heat from the air back out as well as make the 13 Merv last longe) because I like fresh clean air as opposed to stale air with tons of CO2. And honestly, I’m so glad I bought this! It is fantastic and definitely cuts down on the heat by several degrees. I was shocked when I woke up the next morning. The air coming through the fan was several degrees higher than the ambient temperature in the room. I used two separate thermometers to test the difference (one set right in front of my box fan and the other one set a few feet away on a table). There was about a 5° difference! And that’s without an AC on. But more shocking, I was surprised to see that it was see-through, not something I was expecting with something that’s supposed to be double aluminum, but it’s great for a door. Yet since I put it up at night, I didn’t realize it was see-through at the time (see-through as in you can see out, but others can’t see in—at least during the day, but even if they can see in at night with your lights on, it still gives plenty of privacy like a curtain), but I still don’t regret putting plexiglass windows in it. That’s the third picture, I ran out of mounting tape for the other ones so I haven’t put them up yet, but because of that you can definitely see how see-through it is and if you don’t want it to be see-through you have to apply a second layer over it. (double it up) And honestly, I could not be happier with how it looks either, it looks so professional and it feels so secure. Another reason I bought this was because somebody else said that it was so durable it could be used outside, so I’m not worried about it breaking down or anything overtime. It is definitely hard to tear and hard to break, but it cuts good with scissors that are sharp. And I still have a lot left over that I’m gonna use for other stuff so it’s a good bang for the buck. All in all, I wish I bought this sooner!

Super easy to install and works amazing! My apartment kept getting up to 82⁰ and literally installed this on my biggest problem window that gets hit by the sun all day in my living room and now my thermostat is reading at 77⁰. I am so comfortable and it was super affordable! I cant even feel the heat from the window where I put this insulation thats how great it works. Side note: if I sound nasally in the video its because I own two cats who I apparently DEVELOPED an allergy to after I bought them 🤧 Anyways dont hesitate, just buy this stuff because it works good and you can easily remove and reapply it to any window!

Perfect for blocking out my son’s window from the morning-noon rising sun. Keeps his room much cooler than before. Reflects the sun rays away. Easy to cut and size for the window. Value is perfect.

Works quite well. Reduced the heat to almost nothing

Very easy to handle

This is excellent. It worked like magic; the room and garage used to be burning hot in summer. Now it is cool, and we can actually breathe in the room.

This product is amazing. It works really well and is fantastic insulation. Highly recommend this product. Cheers!

I haven’t used it yet but appears to be exactly what I wanted so expect it to be fine

I put it on my windows however I used clear packing tape around the edges. It’s a little thinner than I hoped. I had to put a second layer on, but then again the sun really hits my windows on that side of the house. Stickers do come with it to stick on the window however I suggest you use masking tape and tape around the window seal as well for a better coverage
