I come across this video where they talk about the product called SilverGlo.
I'd like to add this insulation into my attic on my own but I am unable to find a seller. I found a similar product in home depot but it's only 1 inch thick or it is a bare styrofoam without the both sided aluminum foil barrier. I need at least 3 inches and both sided radiant barrier. All I can find are the contractors who can do it for me. I'd like to save money and do it myself since it doesn't seem to be a rocket science.
Is it possible to use bare styrofoam and wrap it into radiant barrier foil somehow to make it both sided rigid foam?

Take a close look at most the so called "foil" lined rigid foam boards. You'll notice they are nothing more than aluminum painted paper. For all I know, the silver looking stuff might just be silver paint. One thing for sure, it's not aluminum foil - and THAT is what you need. Silver painted plastic or foam doesn't do crap. So, to answer your question, "yes" you would have a more effective product buying the rigid foam and then wrapping it with sheets of aluminum foil. And, the way to buy aluminum foil on the cheap is to get it from restaurant supply companies. Their foil comes in wider and longer rolls (often a slightly thicker foil sheet than what is in supermarkets) and it costs way less per foot than buying it from a supermarket. That's what I did. Good luck!
