How can I reduce heat build-up by using Shepherd Color pigments?
Most Shepherd Color pigments reflect the portion of sun’s energy called the near infrared (700-2500nm). These wavelengths are not visible to the human eye, yet they constitute 45% of the sun’s radiation that reaches the earth’s surface. Since our pigments reflect this energy, while others absorb, two objects of the same color can have different heat build-ups. Vinyl siding was one of the first applications where the reflective property of these type pigments was promoted, since the PVC can deform at elevated temperatures. A recent application of this property is in roof coatings that help reduce energy consumption. We call this money-saving environmentally-friendly technology Arctic Infrared Pigments.
