Reflective granules are a special material that can reflect sunlight and reduce the heat absorbed by the building, thereby reducing the indoor temperature and achieving energy-saving effects. In roof design, Reflective granules are usually added to roof coatings to form a reflective coating. This coating can not only improve the reflectivity of the roof and reduce the heat island effect, but also extend the service life of the roof material, because the reduced heat absorption means that the aging rate of the material will slow down.
