Colored solar-reflective roofing granules, roofing products including them, and methods for making them
The present disclosure relates to roofing granules, such as colored solar-reflective roofing granules, and to methods for making and their use in roofing products. One aspect of the disclosure provides a collection of colored solar-reflective roofing granules, wherein substantially each roofing granule includes an inner layer of a porous ceramic material, the pore size and material of the inner layer being selected such that the inner layer is substantially reflective of infrared radiation; and disposed about and substantially surrounding the inner layer, an outer layer of a substantially colored ceramic material, the outer layer of substantially colored ceramic material being substantially transmissive to infrared radiation, the collection of colored solar-reflective roofing granules having a L* of no more than 60 and a solar reflectivity of at least 30%.
