Rated 3.8 out of 5 by 12 reviewers.
Rated 4.0 out of 5.0 by Seems to work... The temperature in my attic is noticeably lower +/- 20 degrees. Relatively easy to install but can be a challenge in tight spaces (at the low end of the rafters). It took about 12 hours of work to install about 1000 sqft. (200 pcs). Had a little trouble because the last 10 pcs in the box didn't have the wires (that hold the panels in place) in them. June 13, 2011
Rated 3.0 out of 5.0 by Great material, Poor labor working quality The material itself on each sheet seems reasonable nicely of the price, BUT, each piece has different length and width (some 1-2" longer/short than standard indicated as 16"x48") and the layout alignment between the foil sheet not evenly produced.

Rated 5.0 out of 5.0 by This product was easy to install... We just completed installing 800 pieces of this product and it was very easy to install. We have already noticed that our heating system seems to be running less and our house is warmer as a result of this product. We hope that next summer we will experience a good result in reducing the heat in our attic and saving on our electric bill. December 20, 2012
Rated 4.0 out of 5.0 by Installation tip I've read several comments about difficulty compressing the wire rods to insert the panels between the studs. My 16" on center studs were accurately spaced so I had an easier time by first bending the rods slightly into a curved shape. An inch or two helps a lot, just don't over bend them or they won't hold in place. December 3, 2014
Rated 4.0 out of 5.0 by As described It installed easily enough. Like others have said, I needed to bend the bars a bit to get it to fit. My rafters aren't evenly spaced and I still had no problem. Its too early to say how much energy savings there is, if any. I've only had them installed for a few weeks. February 10, 2015
Rated 5.0 out of 5.0 by Easy install Though I had to wait for cooler weather to install, we are pleased with the ease of installation, trimming, etc October 4, 2011
Rated 5.0 out of 5.0 by Easy to Install Enerflex is a very durable reinforced radiant barrier. The two metal rods in each panel hold the panel in place between your rafters. It was very easy to install. February 17, 2012
Rated 3.0 out of 5.0 by Material is harder to put up than it looks Panels have two stiff metal rods that are suppose to hold the panels in place but they are hard to bend into place . Especially in a confined attic September 6, 2011
