A composition for a Coating System (paint) which forms an insulating material being designed to both reflect infrared radiation and have reduced thermal conductivity. The coating system may be either a single Thermal Coating or may be a Thermal Coating used in combination with a Thermal Primer. The Thermal Coating is formulated using conventional techniques and a resin used in paint manufacture, but utilizes primary pigments and extender mineral pigments which preferentially reflect in the infra red area of the solar spectrum. A method of characterizing particulate materials for their infra red reflectivity is described, which provides a means for preferential selection of particulate additives based on their relative visible light and infrared reflectivity. Additionally the incorporation of hollow micro-spheres is desired to reduce thermal conductivity. The Thermal Primer is designed to provide adhesion between the Thermal Coating and the substrate on which it is applied and uses conventional techniques to achieve those properties. However it has been found advantageous to incorporate hollow micro-spheres with low thermal conductivity, such as glass, ceramic or polymeric micro-spheres and/or an extender pigment with low thermal conductivity such as calcined clay to further reduce heat flow through the Coating System.
