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

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 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.

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!

worth the low price for sure

Good product, as described and shipped quickly

Live in Southern California. Super hot in the summer. We cover windows with the reflective foil. Works well keeping sun and it’s heat out.

We purchased this to cover our western windows in California during the summer. So far we are very pleased. Easy to work with. We bought the special aluminum tape which we highly recommended.

Item helps but very thin expected item thicker, use to keep cold out so placed on windows.

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!

This stuff is wicked! Put it on my bedroom window....gets all day sun. Blocks out heat, light. My A/C unit DOES NOT have to work as hard anymore...gets my room colder, with less effort and less water flowing out the back of the machine. Reccomend!
