Exterior solar shading (10) comprises at least one elongate rigid light-transmissible louver (12). The louver (12) has infra-red filter means (24) for preventing or limiting the transmission of infra-red energy, and light redirection means (16) for reflecting visible light passing through the louver (12). The light redirecting means (16) is integrally formed in a major surface (20, 42) of an outer louver element of the louver (12). Preferably, the reflecting of the visible light by the light redirection means occurs in the louver. More preferably, the light redirecting means is a plurality of formations such as recesses, for example, grooves (18), or projections. |
