3M™ Cool Roofing granules are based on a patented technology by 3M and are available in a wide variety of rich colors that can create the perfect shingle color blend.
3M™ Cool Roofing Granules are used on asphalt shingles and are energy efficient, solar reflective and economically friendly. The solar reflectivity allows the roofing granules to reflect sunlight and absorb heat. This technology can reduce urban heating as well as lower energy consumption in climates with essential year-round cooling needs. 3M Cool Granules can help meet local cool roofing requirements for shingles which makes them an ideal choice for green building.
