  • Exterior panels containing algae-inhibiting properties
    Publication number: 20020098110
    Abstract: An exterior panel containing algaecidal properties is provided for inhibiting the growth of algae on roofing materials and exterior siding. Algaecide is applied to the exterior panel on the unexposed surface, i.e., the side of the panel, when installed, is not directly in contact with the effects of weather. Moisture such as rain, dew, melting frost or snow, contacts the exposed surface of the panel and water is transported to the bottom portion of the unexposed surface of the panel via capillary attraction. Water extracts the algaecide and distributes it to the exposed surfaces of the panels and all of the other descending panels.
