ABSTRACT:
A pane of transparent material exhibiting a plane base pane and an integrated structure of parallel ribs with triangular cross-section and corresponding grooves is described which rejects direct solar radiation during a summer season and transmits direct solar radiation during a winter season. The pane can be adapted to a wide range of facade directions and geographic latitudes and the duration of the light rejection season or the light transmission season, respectively, can be adapted to individual preferences by aligning the longitudinal axes of the ribs with reference to the horizontal line and by forming the triangular cross-section in an adequate way. A part of the solar radiation transmitted by the pane has horizontal and upward directions and, therefore, the pane provides pleasant daylight in rooms. The pane is able to replace venetian blinds or other movable protection systems and may avoid overheating of facade walls equipped with transparent insulation. In comparison to common double-panes the pane may save heating energy, cooling energy and/or, respectively, electrical energy for room illumination.
