Glass and translucent roofs


Translucent roofs illuminate the room below, thus providing for a pleasant and friendly atmosphere. Such islands suffused with light create a very special flair inside a building. Being lighted from below, translucent roofs have a very special effect in the night. They can be designed in many different ways, with arcades, sky domes, pyramids, and circular-arc vaults being the most important ones. Apart from having a certain architectural touch, the particular geometrical design will positively influence the static bearing capacity of the supporting structure. Therefore, the latter can be minimized, thus increasing transparency. For example, the supporting structure can be designed as an extremely large-span shell structure with two-dimensional curvature. The greatest challenge are geometrically determined as well as undetermined free formed surfaces. However, using triangular glazing, almost any geometry, no matter how complex, can be realized.

 

The structural materials for supporting structures are mainly steel, but also aluminium, wood, glass fins, as well as prestressed steel cables. Important issues in connection with translucent roofs are sun shading, on the one hand, and, on the other hand, ventilation for comfort cooling or smoke ventilation where required.
