DD48025 Air Double Reflective Polyethylene Insulation Roll, 4-Feet by 25-Feet

Very well made and easy to use. I used it to insulate the back windows in my RV Toyhauler. It has helped cool down the back area by at least 10 degrees and I spend most of my time in the southwest US. I bought the big roll split could cover the big windows in one cut.

Worked right away. We used this to insulate a closet in our unfinished basement, and it was noticably warmer right after installation. Easy to cut and install, too. I'm basically an idiot, and I figured it out.

Little bit of a cheaper product than some of the stuff you can get, but its expected with the price. My irritation was that it was clear they roll from a much larger roll and ran out. About 5 feet into my roll there was a huge tape line and all kinds of clear tape around it from another fresh roll. Otherwise, the product works. Just plan on needing to cut out and scrap a few feet and you wont be disappointed.

This is a good product and I am sure will perform well. I gave it 4 stars because it is not quite as good as the InfraStop brand insulation which is just slightly thicker and stiffer. Don't know why it didn't come up on a search when I needed more this year.

this is a great product for insulation. I have made a "hillbilly" yeti cooler from this and it kept food cold for 5 days in a hot cabin this past summer. then used it to insulate a wall in my garage.

I put this in my camper and it really made a Big difference. Before I installed it I had a hard time sitting in my recliner in the morning. it made all the difference in the world. One roll covered all my window in my fifth wheel. I bought another roll and will put it in my cabinets on the outside wall. Great buy!!

Used to insulate inside of small building. Easy to cut and effective.

Helps to filter out some light but really do not see much help in keeping heat out. I suggest doubling up the material. As far as the seller, I recommend they filled the product and it was delivered BEFORE promised.
