Reflective Foil Insulation, Double Reflective Bubble Insulation Sheet, Aluminum Foil Bubble Shield, Radiant Barrier Roll for RV Windows Weatherproofing (23.6''x 10Ft)

Purchased this to cut and fit into my RV bedroom windows more for privacy than keeping things cool. Was very easy to work with and cut. It comes with stickers to help hold it in place. It is great quality keeping the room dark and cool on hot days. Best part I’m not flashing neighbors at the campground. I’ve recommended this to others I know.

I got it when it was going to be really cold over thr winter. Like stupid cold for the East coast with lots of snow. I put it my daughter play room, and the living room. I couldn't believe how good it works. So I put what I had left in her room. It now is so much cooler than other rooms upstairs. So now I'm getting more for the master bedroom. It gets the morning sun.

Very easy to work with. I bought the big sheets because I had some larger areas to cover. Keeps the heat out nicely. Also included sticky dots to keep it in place. Worked nicely for my RV.

I have a sliding glass door that’s behind my chair before I work at home during the summer so much heat comes through the glass. This actually blocks out a lot of the heat, especially the sun, so you know I don’t get to clear on my computer screens easy to put up. The only thing that I don’t like are the sticky tabs say same with it they should do the alien tape so you really can’t tell how it’s put up from the outside and it doesn’t help once it gets hot. They come off.

Works good, just smaller than I expected

Works well on insulating windows and doors

Works great for keeping the wind and cold drafts out of my camper. I noticed a difference as soon as I installed it! I'm sure it will be cooler in the summer as well since it insulates so well. I have tried several different ways to insulates my camper, and this foil has worked the best. It doesn't tear easily, but it's easy to cut and measure. I used velcro to adhere it and it worked out great!

Very thin and flimsy but it will do the job.

The product was as described and will be very useful!

I live in an old apartment building with poorly insulated, southeast facing windows. I got fed up with having to replace my air conditioners EVERY YEAR because so much heat was blasting through the windows, even with blackout curtains. I decided to give this reflective insulation a try. I decided to install the insulation on the outside of the windows, because it was too hard to get at the windows from inside with all the furniture in the way. You can install it inside if you prefer. I used metal furnace duct tape because it's heat resistant and reflective. I also bought a digital thermometer for my living room so I could see if the insulation made a difference. The insulation is lightweight, easy to handle, and easy to cut. I'm an old single lady and I was able to cut and attach the insulation on my windows in about an hour. The tape was harder to handle than the insulation. After installing the insulation I noticed the temperature in my living room went down by about 10 degrees C. Since then I've observed that my portable AC units aren't constantly running trying to cool the rooms anymore. Hopefully I can stop having to replace them every year from now on! If so, this insulation will definitely pay for itself. I haven't decided yet if I'll take it down in winter. My landlord hasn't complained about the insulation on my windows. Maybe he knows I'm saving him money on hydro. If you're a renter you might want to double check that your landlord will allow you to use this insulation.

Used to cover windows in garage in the winter. Worked wekk, saved heat

Used this to insulate the windows in my RV. Works very well. I was able to do 4 large windows with 2 packs. Good stuff. Ordered 2 more!

Cut out to use in RV window and keeps the heat in way better even in -20. Easy to cut and wil not tear after it’s cut.
