Whenever one has a Penthouse flat with glass or polycarbonate ceiling, or a roof top restaurant / conservatory, direct incidence of solar radiation is a cause of major heat generation in the area below. Skylight blinds in special sunscreen fabrics are the only solution for this challenge.
The blinds are made out of imported screen fabrics which are supported on both sides by aluminium track guides and driven by a set of drapery motors. These are basically roman style blinds which fold and stack up at one end, the only difference being that here they do not move in a vertical plane. They can be in a straight, inclined or even curved plane.
