Virtual weather-proofing can only e achieved y the susequent use of eliminators. WG-F

6 Installation Details Type WG WG WGE (split on or dimension) If the dimension is more than 1985 mm or the dimension more than 1980 mm, then the louvre is su-divided into two sections which can then e mounted either side y side or one on top of the corner. Type WG (linear construction) Type WG louvres are availale in linear construction if the dimension is more than 1985 mm. The width of the separating mullions is x 0 mm. Linear louvre construction for > mm consists of two end sections. Linear louvres construction for > 985 mm consists of two end sections and any numer of centre sections. Masonry suframes may e used for installation if required.
