Reflective Bubble Window Insulation for Summer Heat, Sun Reflector for Windows, Insulation Roll for RV Window Insulation, 24"(W) x10 Ft (L) Window Insulation Kit, RV Windwow Coverings.

I liked it so much I did a second purchase and going to do a third. It is very easy to cut. I sew so have rotary cutter which is amazingly easy to get professional cuts. One of the reviews stated it rips easily. Did they use it outdoors instead of indoors? We use it indoors and it works great. Easy to fit and tape with just painters tape. One word of warning though, while painters tape easily removes from most surfaces, it does not remove from this reflective foam. It will tear. Love the reflective light and decrease of heat loss. I even used it on cold walls wit cutting drafts and warmer rooms. We have home extension with lots of windows which are great to look out, but cold in winter even with low e glass. Very happy with this product. Great for interior windows or walls.

Works really well on the camper windows. Keeps the hot sun out. Easy to install. Wasn’t cut for a great fit. It’s thin but it really does a great job. Adhesive seems to be holding well also.

I’m very happy with it! It has held up great through the recent heat, and I’m excited to enjoy it all summer long. I also used high-quality 3M Velcro for extra support, and the combination has worked perfectly. I wish the sizes would have been different but I made it work. Super easy to work with and reusable!!

works great for a camper trailer. This is not a black out style foil, little light still bleeds through but reflects most of the heat.

Perfect for the camper wi does block the heat

This is just 'ok'. Bought to supplement a bunch of Reflectix we already had installed around our campers. Generally, it is fine, but the air pockets (the 'bubbles') are significantly smaller than the name brand. We actually ended up buying more of the name brand to use on top of this as it was so thin that it just didn't quite do the job on it's own to keep out the heat.

My apartment gets very hot in the summer from direct sunlight, and this has been a huge help. It blocks out the sun completely and keeps the space much cooler, so I don’t need to run my AC as much. The insulation is thick, high quality, and seals well with no odor. The Velcro adhesive on the window can sometimes melt in high heat, but extras are included and easy to replace. Just be gentle when peeling the Velcro from both the sheet and the window to avoid moving the piece stuck to the window.

It's working perfectly. My room receives a lot of sun light and heat in the morning and it was unbearable to be there after 7 am, not to say to sleep. It was like a sauna. I put this in the window, a big French window/door, and the average temperature changed from 88⁰ to 80⁰ (31 to 27 ⁰C). So, for me it's a big dealI recommend it.

This is not thick enough, so if you are using to block light as well as insulate, get something thicker.

Love this stuff. Our bedroom in west facing and above an all brick garage. The sun pouring in, even with blackout curtains caused our bedroom to heat up. This thermal barrier reduced heat by 90%. Easy to cut to size and comes with handy velcro stickers

Use it in my camper van for the windows. Works really well to block out heat or keep heat in when it's colder.

It is folded not rolled, which is not ideal. No size on the package, so I will have to see how big it is when I get it opened at our trailer.

The product was not what it showed. It came in a bunch of chunks and some of them had cuts in them. Worst product ever and false advertising
