Screens & Louvers
Glass louver consists of parallel glass panels set in a frame. The louvers are locked together onto a track, so that they may be tilted open and shut in unison, to control airflow through the window. Main purpose of a louver: to form an outer skin for solar shading purposes. Typically, the glass panes can rotate to control the sunlight / shading. Screen constructions also exist, whose primary function is to provide partition glazing (exterior and interior applications).
