Robertson Continu-Line Louvres are field assembled louvres designed for large openings where continuous horizontal line appearance is desired. Design flexibility is possible with unlimited louvre heights and widths, together with mitred corners or corner flashings. Back-up panels, insulated or uninsulated, are available for closing any portion of the louvre area required. Vertical louvre supports are supplied by Robertson and are normally spaced at between 1200 mm and 1800 mm centres. Size and type are to be determined by Robertson, based upon specified design load information.
