REFLECTIVE INSULATING BLINDS FOR WINDOWS AND THE LIKE ABSTRACT OF THE DISCLOSURE Disclosed is an improved blind for use with a window for transmitting sunlight into a room, the blind comprising a plurality of coupled, horizontally extending thermally insulating slats. Each slat has a front face, a rear face, and a pair of longitudinally extending edge faces with each front face being a reflective transversely concave surface. The slats are rotatable about their axes between a blind-closed position, where adjacent slats are in partially overlapping relation and form a substantially continuous, generally vertical surface for providing window insulation, and a blind-open position where the slats are in spaced, super- imposed relation, with their reflective concave surfaces having upward and directly exposed to the sunlight. The reflective surfaces have a curvature reflecting most of the sunlight incident thereon directly onto the ceiling of the room to maximize solar energy input to the room while minimizing glare. The transitions between each of the edge faces of a slat and the back face thereof are sloped toward each other to enlarge the light-entrance and light-exit regions defined by adjacent slats.
