COLORSTEEL BOUNCE is a unique paint primer and top coat system that works to reflect the sun's energy allowing both the roof and the internal environment to stay cooler on hot days. It performs like an extra layer of insulation, making it easier for air conditioning to keep buildings cool, and reducing cooling energy costs. COLORSTEEL BOUNCE is a bright white colour that has been developed to deliver optimised solar reflectance for environmental benefits. The nominal solar reflectance is 77%.

COLORSTEEL BOUNCE absorbs less heat on hot days, working to protect the roof and its supporting structure from temperature extremes. Lower thermal stresses can help a roof to last longer.
