RETROLux A: Outside venetian blinds for higher demands

RETROLux A louvers have two distinct surfaces: one, which is angled steeply,  works as a retro-reflector, reflecting back heat from the sun; the second surface, oriented flatly, admits sunlight and improves interior daylighting.

RETROLux A blinds have different tilt angles according to the angle of view from inside. In the upper portion of the curtain, the blinds are oriented horizontal to admit light and improve interior illumination. In the lower portion, the blinds are oriented more steeply to keep the workspace free from glare.
