Reflective Bubble Insulation, 48" x 10Ft, RV Insulation | window heat blocker, window insualaation for summer heat, double side aluminum foil for rv window insulation, save energy

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.

I purchased this for my daughter's room that gets constant sun exposure all day causing it to be the hottest room in the house. I installed it on the inside of the windows using the Velcro dots provided and the difference is unbelievable. The roll covered all 5 windows when cut to size and I even had extra to do my son's window that faces the sun. It doesn't black out her room completely but keeps heat out for sure.

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 deal I recommend it.

It shows this is in a roll, it is not, it is folded, therefore it has creases in it and was on the thinner side. I kept it and using it just cause I didn't want the of hassle and sending it back

Shows to size plus very thick

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.

Super easy to use, easy to cut to size, reflects the heat outward and significantly decreased the temperature of the room we installed it in. This price is also a bargain. We went to Home Depot and there were no comparable sizes for the price. This was overall a great purchase! I will order again if I ever need this product! You won't go wrong ordering this.

Completely disappointed with this and sent it back to Amazon immediately. First thing I noticed was the Amazon box, thinking "there's no roll in that box." Opened it up and there's this tightly folded material inside two layers of packaging that was so taped up, I had to cut and rip it apart. I realized the stuff was thin and obviously had serious crinkles from being folded, as others mentioned, and I laughed when the inside paper still showed it as a roll. False advertising! But not until I put it up to the light did I see HOW thin. This stuff is see-through! Didn't keep the heat from the glass, could see the sun, my hand and window frame right through it. Do yourself a favor and don't buy what I now know to be only .12" thickness. It's a waste of your time and money. I am including pics with the sun shining through, the ability to see the window frame, and a comparison of thickness (if the pics make sense) of this film and another brand, side by side.

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
