microlouver

A microlouver is a shading and privacy technology used in architectural glazing. It consists of a dense array of tiny blades embedded within or behind a glass pane to control visible light, glare, and the level of privacy while maintaining outward visibility.

The micro blades tilt to intercept direct sunlight or glare, reducing solar heat gain. Some microlouver systems are passive with fixed tilt angles, while others are active, allowing manual or motorized adjustment. Advanced variants may use microelectromechanical systems for precise, rapid tilting.

Applications include curtain walls, skylights, storefronts, and office facades where daylighting and exterior views are valued but glare and privacy must be managed.

Construction and materials vary; blades may be metal or polymer with coatings and can be placed within laminated glass or mounted behind the viewing pane. Systems are designed to withstand weather exposure and maintain performance over time.

Benefits include improved daylighting quality, glare reduction, privacy, and solar control, which can lower cooling loads. Limitations include higher cost, maintenance needs, potential complexity in integration with existing glazing, and considerations for cleaning and long-term reliability.

Microlouver technology is part of broader dynamic shading and glass systems, often used alongside other daylighting strategies in modern buildings.
