1 Answer


According to Luke Rogers of Innovative Insulation Inc. in Arlington, Texas, 'About 93 percent of all the heat entering your roof is radiant heat, so in climates where the biggest issue is keeping heat out in the summer, a radiant barrier will be more effective than conventional insulation. We recommend using a radiant barrier in conjunction with conventional insulation. They can work with one another to maximize the home's efficiency. Consider the price, too. The cost of materials for a radiant barrier is about half the price of fiberglass and one-third the price of foam, and you can install it yourself.'
