Radiant barriers usually consist of a thin sheet or coating of a highly reflective material like aluminum applied to one or both sides of a number of substrate materials. The potential benefit of attic radiant barriers is primarily in reducing air-conditioning cooling loads in warm or hot climates. Straight from the Department of Energy: "Radiant barriers are materials that are installed in buildings to reduce summer heat gain and winter heat loss, and hence, reduce building heating and cooling energy usage.
