3po3 on Feb 12, 2011R values are a measure of thermal resistance, measured as area multiplied by temperature and divided by BTU, or unit of energy. Without getting really technical, it just means that R15 insulation will block heat transfer slightly better than R13, but neither is particularly serious insulation.Helpful Reply
