Tile Classifications and Ratings

The New South Wales Building and Sustainability Index (BASIX) has classified colours into light, medium and dark on the basis of their solar absorptance as an easy guide for home builders to use when choosing materials for their homes. Please see the tables below for the solar absorptance and BASIX colour classification for our products.

SA = Solar Absorptance. The classification of colours in the NCC is based on solar absorptance, which is the inverse of solar reflectance, expressed as a ratio between 0 and 1. A SA value of 0 indicates that a roof absorbs none of the solar energy applied to it while a value of 1 indicates that a roof absorbs 100% of the incoming solar radiation.

NCC = National Construction Code. NCC has classified roof colour on the basis of their solar absorptance, referred herein as Light (< 0.475), Medium (0.475-0.7), and Dark (> 0.7).
