APOC® 11 White Top Ceramic Roofing Granules provide long-lasting, weather-resistant protection from the elements. These roofing granules are coated in white ceramic. APOC® 11 White Top No. 11 Ceramic Roofing Granules are composed of a high quality mineral rock and are the same granules used on BUR, SBS and APP mineral-surfaced sheets. APOC® 11 uses only premium grade pigments and a high tech ceramic coating process to permanently protect and coat the granules. APOC® granules provide a durable layer of protection over asphaltic and polymeric materials preventing UV deterioration and premature aging. They are also used to add toughness and durability to a variety of coating when used in walkway systems or other substrates which receive a lot of wear.
