60° prisms guide the light
So the incoming sunlight can be guided, the glass prisms are adjusted to the sun‘s angle, thereby actively functioning as a tracking system. The distance between the profile rods is determined by the 30° angle of irradiation. In all the examined angles of elevation, direct light is refracted very effectively into the interior space below owing to total reflection.
With the correct geometric arrangement of the “Conturax” profiles, the system provides angle-selective sun protection. Even for this application, SCHOTT‘s 60° prisms are arranged perpendicularly, yet rigidly on top of each other. The steep angle of the summer sun is stopped with total reflection, while all other lower sun angles are guided to the interior space, both by light refraction and total reflection.
The new façade concept presented at the glasstec should not only give architects and planners an understanding of the aesthetic effect that the products have, but should also demonstrate their functionality. As proven by the overwhelmingly positive response seen at the fair, the experts have already adopted this innovative concept.
