reflectance. The solar reflectance represents a wider range of wavelengths than
the visible reflectance and is often slightly less than the visible reflectance for a
specific material. It is important to make sure that the reflectance quoted by a
manufacturer is the solar reflectance. If not, then the solar reflectance must be
gotten elsewhere. Figures 2.7.1 and 2.7.2 show example photos of weathered
