PBR is essentially a holistic system of content creation and rendering, which can and often does have variances (generally shader models or texture input types) in actual implementation, depending on what tools or engine you use. 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.
