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?
