This disclosure provides a new type of shading device for windows. The shading device comprises two sheets of glass, a blind with a plurality of slates, and an actuating device rotating them. The slates are painted with a low reflectivity coating on one side and a high reflectivity coating on the other side. The blind is installed inside the air tight chamber formed by two sheets of glass. In addition, a low emissivity film can be applied on the wall of the air tight chamber. The shade device employs a control system to adjust the angle of the blind slats in response to various input signals. |
