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.

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!

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.

worth the low price for sure

Works good, just smaller than I expected

Cut this down for window shades for my car. Easy to work with. Good quality, lightweight. HELPS!

I taped this to the inside of the storm door that gets the hot afternoon sun. It has made a huge difference in my garage. I used Velcro with sticky tape already on it so I can remove it in winter.

I tried to use it as a car windshield shade, and while it does well to shade the window, it is thin, so I can see the sunlight through it, and it kind of has a blue glow. It also doesn't stand up by itself like a normal sunshade would. I think if you were to double it up, it might work better? I'm thinking about sewing 2 layers together! I was able to cover my sunroof which was my most important window to cover and it was pretty easy to cut. I used the stickers that are included just to get it in place, and I was also thinking putting cardboard up behind it would also be good insulation.

Très bonne qualité de plastique métalisé. Très résistant et efficace.

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.

I used it on one large South facing window. Helps keep the room cooler.

Will work great.
