Reflective Bubble Window Insulation for Summer Heat, Sun Reflector for Windows, Insulation Roll for RV Window Insulation, 24"(W) x10 Ft (L) Window Insulation Kit, RV Windwow Coverings.

I bought this to help keep the sun and heat out of our front room. Our house faces full west and it gets so hot in the summer. The outside temps get well over 100 degrees where I live. I bought this to go on our front room living room window and it cut down the heat so much our AC would run constantly from noon on during the day. Now it starts running from about 4 PM till about 9 pm when the sun goes down so it significantly helped our AC unit so that it would run all day. I am going to put it up again this year and i am happy i bought them. One thing if you buy these and life in an hot place like i do make sure you cover your windows only i made the mistake and covered the window sill (where the track is) and it warped it cause it got so hot so just be sure to cover glass part on the windows only.

In the desert it can get up to 115 in the summer. Having a big slider window on the side where the sun beats it all day makes it hard for the AC to keep it cool. Putting this up in the window has made a huge difference. Yes, you loose out on the light, but to me it’s a willing sacrifice. This came with its own adhesive too, which makes putting it up easier if you don’t have your own. It’s also very easy to cut so you can customize it to your window size. As far as how well it works reducing the heat… literally night and day! I can no longer feel the heat that radiated from the window before. I cut a couple “peek holes” so we can look outside and opening them you can instantly feel how hot the window actually is, but on this side it’s room temperature. Very good investment!

If you need a cheap reflective material this is a good choice. If you are looking for a reflectix alternative just buy the name brand. This is very paper thin and doesn't have the same insulation as the actual reflectix. I learned this the hard way when I could have had the real stuff for $3 more. Oh well I used it for my lids and ordered another roll of the good stuff. This works just not well. The Velcro they included is beast tho! It will hold anything

Living in TX comes with serious heat during summer. Had two rooms facing the afternoon sun and no matter how cold the AC is turned on, room was still hot. This covering the entire window with double stick tape really helps cool the room! Couldn’t believe how much of a difference it made.highly recommend this for any house with windows facing the sun directly during summer. Great for those who have RV’s as well!

This might sound ghetto but I used this to stick on my window to help block out the heat and it does great. The heat stays out and my room feels so cool. Love it.

Why did you pick this product vs others?:I got the bubble insulation, but it was NOT a roll like the picture it was a folded flat piece.

Why did you pick this product vs others?:Keeps heat out and keeps it dark in the room.

This thing really helped keep the heat out of my windows
