Statement:
The LightLouver Daylighting System provides daylighting and solar control in one remarkable product. Using a patented, passive optical design, the LightLouver Daylighting System redirects daylight deep into the space while eliminating glare and all direct sunlight penetration onto work surfaces – providing excellent daylighting and solar control for east, west and south facing fenestration in new and existing buildings. Integrated into the building fenestration design, the LightLouver Daylighting System provides uniform ambient lighting, enabling electric lights to be turned off or dimmed. Mounted inside the building, directly adjacent to the daylight glazing, the LightLouver units are protected from the weather, and pivot to enable cleaning of the daylight glazing. The LightLouver Daylighting System eliminates the need for costly and unsightly exterior of interior light shelves and provides superior daylighting performance.
