Innovative COLORBOND® Coolmax® steel is a tailored roofing material designed to provide and maintain high solar reflectance.
Tested by scientists in the laboratory and under extreme Australian conditions, COLORBOND® Coolmax® steel is BlueScope’s ultimate product for cool roofing performance whilst maintaining the COLORBOND® steel durability that’s required for commercial and industrial roofing applications in Australia.
Available exclusively in the colour Whitehaven®, it has a nominal Solar Reflectance (SR) of 0.77, meaning that 77% of the sun’s heat is reflected1.
Achieving a Solar Reflectance Index (SRI) of 951, the highest of any BlueScope product, COLORBOND® Coolmax® steel may help to2:
- reduce roofing surface temperature
- keep the building interior cooler
- reduce demand on air conditioning and reduce energy costs*
- reduce peak cooling loads
- mitigate effects of Urban Heat Islands
- keep solar panels cooler and boost their performance
- earn provision points with Green Star3 and may improve your NABERS4 rating

- Values are based on new product and measured in accordance with ASTM E903-96 and ASTM E1980-11. COLORBOND® steel products’ Solar Reflectance (SR) and Solar Reflectance Index (SRI) values may vary as product ages.
- Results will depend on a wide range of factors including roof colour, roof shape, level and location of insulation, type, location, shape, and function of the building.
