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

Awesome! Used to make sun blocking panels for windows. Windows are 36" x 78". One panel is 8" less wide due to portable A/C insert. Measure window twice. Cut once. Used staple gun to attach 1/2" square dowels to vertical edges. Easy to pop in and out of windows. Have taken in and out many times over past month - very sturdy material!! Will be easy to roll up for storage. Seriously easy and helpful. Decreased room temperature by 15 degrees in upper rooms that get afternoon sun and sit above lower level's asphalt shingled roof. Very noticeable difference!!! Looking forward to less $ on power bill. Wish I'd have made these years ago!

I love this window insulation! It’s been a lifesaver during this heat wave—my room stays so much cooler, and it blocks out the sunlight completely. This has been especially great for my husband, who works night shifts and needs to sleep during the day. Easy to install, effective, and worth every penny!

Made trailer curtains for the rodeo trailer and lined with this. I had done the same for my son's rv .. in both cases it has cut way down on the heat and cold of the trailer, its nice not being at the mercy of outside temperatures. In the case of my son, it also keeps his AC from freezing up. Its easy to cut, rolls easily in my curtain design, and is durable. Its a quality product at a competitive price point.

Works great in my kids room

If you live in a camper in the Florida heat you need these badly. Unless you have some kind of tent over your camper or an extreme amount of shade, you’ll get baked alive. However, if you have these and install them on your windows properly, you won’t be able to tell either way. Once we sealed our windows off with these, we were finally able to keep the temperature down in our camper without constantly running the central AC unit. I just run my portable Whynter AC unit and it cools it down all day long—sometimes it even gets too cold. Never thought I’d say that in Florida heat. Go ahead and buy these if you’re having heat issues and need something cheap and easy to install.

I live in an older apartment building and, while I love my apartment, it has no ceiling fan in the living room. I live in south TX and the heat here can be quite unbearable. As soon as the summer hit, my living room turned into a sauna. Its been too hot to even sit on my couch. I considered blackout curtains but I didnt know how well they would really work when it comes to keeping out the heat, so I bought this instead. INSTANT relief from this heat!! I covered both windows in my living room and immediately felt the difference. Now I can actually enjoy my apartment again and not feel like I'm melting when I'm reading a book on my couch. No A/C problems by the way, the windows were the issue. My A/C works like a charm, and so does this item. Thank you!!!!!!!

Why did you pick this product vs others?:Great for covering garage door windows. Super reflective, and easy to cut. Keeps my garage cooler in this summer heat. Highly recommended.

This was a huge help in making my room upstairs much cooler. I’d previously tried to use some blackout shades purchased here, but it was not helping with the heat. That’s when I did more research to see what could help reflect the sunlight and this product popped up. I put them up today and noticed immediately the difference in room temperature being much cooler. These are definitely a necessity if you live in Texas or anywhere hot where your window faces the direct sunlight.
