On the exterior of your house, ceramic-filled paint is effective year-round, but it is particularly effective at blocking the summer sun's heat. New insulating ceramic-filled and no-stain paints Since ceramic particles block radiant heat, it is difficult to give this paint a typical R-value rating. These thermal properties make this paint a good insulator for house walls too. This same type of ceramic particles is used in the heat shield tiles on the space shuttles to block reentry heat. Second, the ceramic particles dissipate heat like a dark cast iron radiator. In the winter, your body heat bounces back off the walls painted with ceramic-filled paint for a warm feeling. These particles have a unique combination of thermal properties.
