Performance tested to AS/NZS 4740:2000 Louvreclad Jupiter Series Drainable is a 125mm pitch extruded aluminium louvre that achieves Class C 86% effective rain defence, Class 2 aerodynamics, 55% free open area and an additional drainage channel to mitigate the cascade effect. With a drainable catchment gutter integrated into the blade profile rain drops no longer cascade down the face of the louvres, making it suitable for industry-standard applications like plant room screening, air intake and exhaust louvres, and louvre doors where there a little or no eaves overhead.
