After paying full price to have radiant barrier paint installed in my attic, I discovered that the product they used (Radiosity 300) was about 12% as effective as Heat Block 75, the industry standard. Not only that, but they applied it a lot thinner than recommended on the manufacturer's web site, so it was virtually useless. "Gee I'm sorry," said Mr. Mayfield, through the salesman after I stopped payment on the check. "I honestly didn't know."
Pros: bloows cellulose for cheap
Cons: Doesn't know squat about radiant barrier
