Abstract: A ceiling system includes a support structure configured to be installed in a ceiling area of a variety of room types. A ceiling supported by the support structure may cover the majority of the ceiling area and may include light sources to light the room. The ceiling may be defined entirely by panels extending continuously from one end of the ceiling to an opposite end of the ceiling, arranged side-by-side with troughs in between. The panels may themselves be the light sources. Alternatively or additionally light sourced may be disposed within the troughs.

Abstract: A glass sandwich plate comprises a spacer arrangement (12) disposed between two glass panes (10, 11) and formed as a continuous unit from a 0.2 mm thick aluminum sheet by punching and deforming such that webs (18) are formed which extend at different angles with respect to the glass panes. The webs (18) extend between plane connecting areas (17) at which the spacer arrangement (12) is glued to the glass panes (10, 11) by means of a radiation curable acrylate or epoxide adhesive. With this structure, the sandwich plate has a high breaking strength at low weight and is suitably used for sight and sun protection.
