Abstract

See full text

A roofing product can include roofing granules that can include base particles and a coating covering the base particles of the roofing granules. In a particular aspect, the coating can include a compound that includes a metallic element; and nitrogen, carbon, or a combination of nitrogen and carbon. In another aspect, the coating has a reflectivity of at least approximately 17% for a radiation having wavelengths in a range of 1000 nm to 2500 nm. In a further aspect, the particular coating has a coating reflectivity no greater than 99% of a TiO2 reflectivity for such radiation. A coating can be formed on a base particle of a roofing granule using a fluidized bed. In a particular aspect, coating can be performed as a chemical vapor deposition or a sol-gel process. If needed or desired, the roofing granules can be doped to achieve their desired properties.
