Energy Efficiency

The ceramic pigments in our exclusive Alunar® Coating System embedded with Teflon™ Surface Protector help reflect and emit the sun’s Ultraviolet rays. On a sunny day, these UV rays typically penetrate traditional roofing materials and greatly increase the temperature of your homes attic space resulting in higher cooling costs. Metal roofs can conserve energy by reducing cooling costs up to 25%*.*As per Cool Roof Rating Council (CRRC) and Oak Ridge National Laboratories (ORNL)
