Rated 5.0 out of 5.0 by Steve Easy Install Radiant Barrier/Rafter Vent
Easy to install when rafters are on 16" centers and the rafter bay if free from obstructions - and you have access. Two steel flex wires cross horizontally at 1/3 and 2/3 up the length that spring into the rafter sides. Obstructions in the bay may require some cutting of the product. I would not recommend adding any rolled insulation, as the installed product forms a non-rigid half cylinder shape in the bay that would be difficult to cover without crushing the shape. Also air space and clean shiny surface improves performance of radiant barriers.
+Easy to install.
+Doubles as a rafter vent. Keeps hot air close to roof deck, away from living surfaces.
+Skipping installation in areas where you don't have access doesn't reduce performance in areas where you can install the product, since this is not an air seal. Therefore install it in areas where you have access; skip crawling into god-forsaken areas of your attic.
-Assumes 16" on center rafter spacing, with few obstructions.
-Sometimes the spring wires bend instead of spring.
-Wires can tear out of product unless you install gently.

I am in the installation process now. It is well packaged and easy to install. I am only about 20% done and I can already notice a significant temperature drop. I am pleased.

Rated 4.0 out of 5.0 by JKLK 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.

I got this product to apply an additional barrier under a sun porch that already had insulation between floor supports. Unfortunately spacing between was 12 to 14 inches so instead of placing between supports I stapled to bottom of supports.

I really liked this product. I purchased more than I could use but it was a great product and easy to use. I used it for insulating walls for a renovation project I was doing. Once the panels were installed, I could tell the difference right away. It works really well.

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.

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.

Rated 3.0 out of 5.0 by OraclePro 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.
