White ceramic roof coatings were found to be significantly better than galvanized sheet metal in reducing the solar heat gain on roof panels like those used for the roof of a farmers stock peanut warehouse. However, the ceramic coatings were not better than a white acrylic latex paint in reducing solar heat gain. After four years of testing, there was no apparent difference in the durability of the ceramic coatings or paint. The ceramic coatings were reputed to have good thermal insulating properties, but these were not apparent in the study. The maximum mean two-hour temperature during the study occurred on September 14, 1991 with the galvanized control panel reaching a high of 69.3 C. The ceramic coated and painted panels due to their solar radiation reflective properties were approximately 19 C cooler than the galvanized control and approximately 14 C warmer than ambient temperature.
