    Cuts very easily with scissors or a utility knife
  

*by L***N on Reviewed in the United States on August 4, 2016*

I purchased this product when I ran out of Arma Foil radiant barrier and only needed a few hundred feet to finish the job.  I certainly appreciated the lower price of this product.  I think the shipping weight of Arma Foil is 21 pounds versus 16 pounds for this product.  It is much thinner and certainly tears much easier, but you really have to be trying to make it rip.  Cuts very easily with scissors or a utility knife.  For future projects, I will certainly use this product for “blanket style” covering of existing insulation.  It moves around very easily by hand or with a telescoping handle that has a nail at the end.  My rafters are 24” in center, so the 48” width is difficult to work with.  Instead, I made cuts are 27” so this gave me 27” x 48” and then I would staple it to the rafters, so that is had 1-2 inches on either side of the rafter.  Took more time to cut the smaller sections, yet it was easier to work in smaller sections.  It has only been a week, but I can tell no difference between the sections of my house where I used Arma Foil versus Super R Diamond.  My AC runs a lot less and I am expecting that my utility bill with be lower as a result.  This is a good product and half the price.  Will be picking up another roll here very soon for another project.

    Good stuff
  

*by D***A on Reviewed in the United States on July 2, 2016*

I keep finding more uses for this, I got it to put over my windows to keep the light and heat out. I had to use two layers to keep the light out completely, but even one layer would have made it dark enough. I also put this up in my plant room to help me control the heat, it works very well. I am able to keep my warmer weather plants warm without the heat spreading to my cool weather plants.

*by Z***Q on Reviewed in the United States on November 28, 2016*

Keeps my house cool, I put this in immediately after moving in and before the first summer in my new home, not sure how much savings it's created but my a/c rarely kicks on and my home is cool. I have a radiant barrier as well as cellulose insulation.
