Cool Roof Rating Certification

SHEERFILL^® is the first ever translucent roofing membrane to be certified by both Cool Roof Rating Council (CRRC) and Energy Star as energy efficient.

CRRC is a California based organization tht rates roofing materials as a "cool" roof.  This is defined by the amount of light a roof reflects, saving energy inside the building.

Energy Star is a federal government program (EPA) which rates many things as energy efficient.  Again, the level of reflectivity of a roof determines its efficiency.

In both cases, the ability of a roof to keep these characteristics for three years is the requirement.
