RetroFlex-louvers are assembled like Venetiam blinds. They are installed either on the interior or within a closed double-skin facade.The aluminium louvers act as efficient retro-reflectors by their micro structured mirror surface. The microstructure is embossed into the aluminium utilizing the mathematics of a Fresnel mirror (R=86%). The smooth surface of the lower side is either white or alu-reflective.
