The LouverShade 2″ Dual Zone system is the most popular daylight harvesting solution for either new or existing buildings. It features the exclusive one piece bracket system that allows installation of both the upper light harvesting louvers and lower view glazing roller shades from a single mounting point for either inside or outside mount to wall or ceiling. For manual (non-motorized) systems, light harvesting louvers can be adjusted to optimal light harvesting positions but not into glare angles based upon the application of tilt limiters that maximize available natural light while simultaneously blocking glare. See section on motorization and control for configuration options.
