Louvre screens

Abstract

Metal louvres are typically used for two purposes: as weather-resisting screens to naturally ventilated spaces such as plant rooms, as terminations to the ends of air-handling ducts where they penetrate the external wall, or alternatively as solar shading on the outside of facades in front of glazed walls or windows. Glazed louvres are also used to provide natural ventilation to winter garden spaces where they also provide light, as in high level clerestorey glazing or in glazed walls in winter gardens in housing. Glass louvres are generally adjustable. Metal louvres are used for air handling ducts or plant rooms, and can be in single, double or triple bank depending on the amount of weather resistance required.
