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

Works well! Def insulates & keeps our space cool. Needs it to reflect some early morning sun in the office. It’s a quick fix for those warm bright sunny mornings.

I live in an apartment that used to be an attic. Poor insulation and I melt every summer and freeze every winter. I put some of this in the skylight of my bedroom and in my kitchen windows and it’s made such a big difference. My expectations were very low so I am very happy with the results. The weather here is getting hot and it’s comfortable in all rooms. I also would normally have three AC’s running but only need one now since the cold air seems to be circulating correctly.

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.

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.

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!!

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...

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

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