Rated 4.4 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by Love this product! I live in Mississippi and this summer was one of the worse. I decided to experiment and purchased this product to put over my windows on the inside of the house. I have shades and sunblock film, but they did not help. While I was installing this over the windows I could feel the difference immediately. It did not darken the rooms and the rooms cooled down quickly. Wish I had tried this sooner. Great product!

Rated 5.0 out of 5.0 by Great product I bought both the rolled barrier and the 2' x 4' precut panels. As I stated in the other review, installation would have been much easier and faster if it were not for having to work around the horizontal & diagonal bracing connecting the engineered trusses together. The rolled barrier was very easy to cut and install for the two gable ends. For my 12' x 16' recording studio, I was able to get both 5/12 gable ends out of one roll, with plenty to spare for patching. I found that my pneumatic staple gun was by far the best for attaching the panels and the rolled barrier. The staples captured both the plastic & metal rods embedded in the barriers, holding them securely to the framing.The hot air layer in my attic is so much cooler now, narrower, and therefore higher up, and the attic floor is actually cool to the touch. This will really help keep my booth ventilation ducts mounted near the attic floor from heating up. July 30, 2013
Rated 5.0 out of 5.0 by Radiant barrier I sed this material to cover house fan opening during the winter. It worked great! June 9, 2015
Rated 1.0 out of 5.0 by Size of the product is not the size on the package The size of the roll varied from one to the other. It was any where from a 1/4 " to 1/2 " short on the width. So you could not run the barrier over two joist at one time. And trying to return it and get the same price was impossible. April 27, 2015
Rated 5.0 out of 5.0 by used this product in an unusual way We bought this product to staple to the bottom of some Besta Ikea cabinets that we hung above some baseboard water heating in an old house. We hope the foil deflects the heat back in the room. It was easy to cut and handle for this purpose. It is sturdier than kitchen foil we could have used. April 1, 2014
Rated 5.0 out of 5.0 by Great product Barrier insulation was very easy to install and it reduced the amount of heat radiating into the storage space through the roof. December 9, 2014
Rated 5.0 out of 5.0 by REASONABLE PRICE I felt that the purchase price was excellent . Plus it helps to save on utility bills. The product is very lightweight, durable and easy to install. October 29, 2014
Rated 4.0 out of 5.0 by it works goes up Eazy light weight and works for what I needed it for. Will buy more if I need it. March 6, 2015
