Reflective Insulation Foam,48" x 10 Ft Window Insulation for Summer Heat,Aluminum Foil Bubble Insulation Roll for Keep Heat,Window Insulation Kit for RV, Thermal Insulation Cover for Window.

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 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’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.

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.

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.

Easy to use and really helps keep the temperature down. I purchased this to use in my RV trailer. I used the window screens as a template. I outlined it with a marker then using a pair of scissors I cut it a little oversized to fit the glass. I placed the cut out between the glass and the screen. Worked out great. The only time I used the Velcro that is supplied, is when I covered the ceiling vents. This Velcro has some good adhesive so make sure you put it in the right spot.

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
