The Influence of the Edge Sealing in Curved Insulated Glass

Jürgen Neugebauer

An essential part of the structural analysis of insulated glass is, to find values for the inner pressure as a result the so called climatic load and the coupling effect in these curved insulated glass units. An interesting aspect of this analysis is the influence of the edge sealing. The edge sealing allows small movements and rotations of the glass at the edges. Depending on the load situation the distance between glass panes becomes longer or shorter. A range of displacements with a value of 0.1 mm up to 0.2 mm depending on the edge system used is possible. This displacement value is not big, but multiplied by the area of the glass panes a difference in the effective inner pressure results, which should not be neglected.
