This heavyweight, laminated shingle is composed of a dimensionally stable non-woven glass fiber mat, which is thoroughly impregnated with stabilized waterproofing bitumen. Dynasty ArmourZONE is distinguished by its random shake-look design, unique high contrast dual band shadow coloration, and superior thermally activated shingle sealant. Colored, ceramic granules surface the top of both layers of this shingle to protect the asphalt from ultraviolet radiation. Each shingle has release tape and mineral powder applied to the underside, thus preventing any sticking in the bundle. Dynasty ArmourZONE features IKO's ArmourZONE wider nailing area for easier, faster shingle installation backed up by ArmourZONE tape on the reverse side that provides enhanced protection against wind loss. Special algae-inhibiting granules have been added to provide long-lasting algae resistance.
