The owner of Ultimate Radiant Barrier previously worked in the heating and air-conditioning business for 30 years. In that time, he saw utility bills continue to rise, and homeowners were unable to do anything to combat it. So, he decided to turn to science to solve the problem, concentrating on the area of the house that transfers the most temperature: the attic. He started making that space more energy efficient by lining it with sun-reflecting foil, which prevents the outside heat from creeping indoors, significantly reducing the cost of air conditioning during stifling Houston summers or slightly cooler, but still stifling Houston winters.
