COLORBOND® Coolmax® steel is specifically designed to provide and maintain high solar reflectance [Nominal Solar Reflectance= 0.77. Solar Reflectance Index (SRI) = 95, 3-year-aged SRI = 921] whilst delivering the same quality and durability that you’ve come to expect from COLORBOND® steel.
Increasing energy costs are a concern for many commercial and industrial building owners and tenants. So, it’s reassuring to know a roof made from COLORBOND® Coolmax® steel in the colour Whitehaven® could help reduce roofing temperatures and keep the building cooler2. And it’s a smart design choice too – not only does COLORBOND® Coolmax® steel help mitigate the impact of Urban Heat Islands (UHI)3, but you can earn provision points with Green Star4 and may improve your NABERS5 rating.
- Nominal values based on new product. SRI determined in accordance with ASTM E1980-11. Solar reflectance measured in accordance with ASTM E 903-96, standard test method for solar absorptance, reflectance and transmittance of materials using integrating spheres.
- Compared to conventional roofing materials of lower reflectance index (SRI), such as ZINCALUME® steel and all other roofing materials in the COLORBOND® steel range. Any savings and or the extent to which a building is cooler may vary and depend upon the particular circumstances of your building, including building location, level of insulation, location of air-conditioning when installed, building shape, building function and environmental factors.
