Sept. 12, 2006: Radiant Barrier Offers Advantages to Commercial Roofs
AUBURNDALE, Fla. - A radiant barrier from Fi-Foil can significantly improve thermal performance of buildings with metal roofs and reduce overall cooling expenses by as much as 11 percent, according to studies by the Florida Solar Energy Center.
Fi-Foil's product, Radiant Shield, when installed under metal roofing reduces the high infiltration of heat from the sun into the building envelope, which is common with most roof systems. A metal roof radiant barrier application includes a 3/4-inch air space. The perforated version allows vapor transmission.
