For a cool roofing product to perform best in hot sunny conditions it needs to have a high Total Solar Reflectance (TSR) and a high thermal emittance. COLORBOND® Coolmax® steel has both. It is cooler than ZINCALUME® steel and the rest of the COLORBOND® steel product range mainly because it achieves the highest TSR. It also has slightly higher thermal emittance than standard COLORBOND® steel because of its thicker paint system.
