Arma foil is high quality stuff
I ordered 3 large rolls of Arma perforated foil to use as a radiant heat barrier in my home attic. It worked well. I could feel heat from hot roof decking on the back of my hand from a foot away without the foil, but when I moved my hand over a foil covered area I no longer felt the radiant heat. Most impressive to me was the quality of the material, as I was able to pull it away from staples to re-staple without it tearing. It was all I hoped it would be.
