Abstract
A vertical or horizontal window or skylight blind or shutter having slats which have two physically different surfaces on each face. The blinds overlap slightly at their long edges when closed, yet they are able to rotate at least 180 degrees around their longitudinal axis. One face of the slat has triangular grooves on it running parallel to the length of the slat. The triangular grooves are coated with a pigment that reflects by specular and/or direct diffusion the sun'"'"'s electromagnetic energy, whereby the room is kept cool in summer and warm in winter.
