Window Insulation for Summer Heat, Reflective Insulation Roll 48 in X 10 Feet, Double-Sided Aluminum Foam Core Radiant Barrier Kit with Tape for RV Windows Garage Door

The media could not be loaded. I actually used this to line the inside of a cat house, which I also bought on Amazon, for the feral kitties in my neighborhood! It was very easy to cut and very functional for my purpose. The size was perfect for what I needed, and it did seem to retain the heat. It also helped limit wind blowing through it in the freezing temps and protected the little feral meows! The tape was also SO HELPFUL. DO NOT BUY ONE WITHOUT THIS TAPE!!

This item worked perfectly for what I needed for. I used it to line and outdoor cat shelter. It worked wonderfully and kept the cats warm from the winter weather. Thank you to the seller who shipped it fast.

Great for screening attic vents to prevent embers from getting in. Fire safety so important.

This was one big sheet. I used it to cover the house windows from the cold weather. It did work for heat retention. had to cut it to fit my 3'x3' windows. able to cover 3. The velcro sticky's worked well.

Extremely happy with this! Just what we needed for a southern facing window in our converted garage.

I was disappointed! It came folded instead of a roll. As a consequence it was horribly creased when I opened it. Lay it flat on the carpet but I realized that it was going to be impossible to install it without looking really bad. It's meant for the ceiling of my sunroom, which it means it's expose and therefor is going to be seen...

I live in an older home with single pane windows. My electric bill was extremely high from the sun beaming in. I tried room darkening curtains and tint. Neither helped. Once I used this product my electric bill dropped significantly! Would definitely recommend for home and RV windows!

Used this along with styrofoam, straw, and a plastic tote to create a shelter for a stray outside cat. Easy to work with. Easy to cut with normal scissors.
