Insulators on the other hand reflect a very small amount of light (~4%) and much of the of light that hits the material diffuses or bounces around the surface creating an even distribution of color. Additionally, loading any old content into a PBR shader does not guarantee physically accurate results. Everything has reflectivity, even they are standardized into 2 major categories.
