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 Foam.

The Reflective Bubble Window Insulation is a lifesaver if your place turns into an oven during summer. I slapped it on my bedroom window, and it legit cut down the heat blasting through—my room’s not a sauna anymore. It’s just a roll of shiny bubble wrap stuff you stick up with tape, so it’s easy to deal with, even if you’re not handy. The sun bounces right off, and I swear my AC isn’t working overtime now. It’s not fancy, looks a bit DIY, but it does the job cheap and simple. Highly recommend if you’re sweating through the season!

I put these up in all of my rv windows and they work great! Just after putting them up, you could feel the air getting cooler.

We bought this to use in our frt side windows of our Class A motorhome. The product works pretty well so far and help keep ALL sun out.. It is a bit thinner then what we thought it would be. In the long run thos it actually worked out better bc we are able to fold it up smaller to fit in over head when not in use.When it come to the Velcro that comes with, it isn't that great. It is pretty cheap and falls off the Aluminum sheet or doesn't stick the window edge it self

Second time purchasing this. We live in an RV full time in AZ. We keep our windows covered, aside for the main one in the main living space, year round. This product has stayed on with no flimsy issues or having to re stick it or anything of that nature. It hasn’t torn even with a one year old trying his best to destroy it.It’s easy to cut down to size and apply the Velcro dots.Overall it does it’s job the best it can against the raging Arizona sun.

I bought this to help keep the heat down in one of my bedrooms and it worked like a charm! It also became a room that I love to take a nap in because not only did it cool it down but totally blocks out the light. I love that you can cut it to fit the window size. I have also used this to help cover items in my cooler and to wrap my wine bottles when I transport them.

We bought this to insulate our vehicle windows for "camping" sleeping in the back in below freezing temps. Unfortunately, this product is not shipped in a roll like the photo shows. Instead it was folded into a small bundle which meant there were creases every 12-18 inches or so. This meant it did not lay flat against our windows and we had to cut it extremely precisely and tape around the edges to get it to stay and insulate well. This made for a very long and tedious process.The insulation itself is fine - a bit thinner and less stiff than I was expecting but still insulated well enough to sleep in our car below freezing as long as we used some tape around the edges. One part of the windshield pulled away during the night when the tape fell and that was the only part of any of the windows that was frosted in the morning (~27 degrees).

Works phenomenally.

I can feel the difference already! 25 degrees this cold morning and it works just great over the bedroom windows and it blocks out the sun. I think two layers would really be great if you love the heat....i may add a second layer when spring hits to keep out the heat.
