Project Description
The requirements for facade elements are steadily rising. Functional and design properties can strongly influence the heat capacity and development in individual glass elements, which can lead to thermal glass breakage. A specific stress analysis of glass edges following thermal stress is not currently defined in the current German design specifications. By its nature, the edge of the glass is the weakest part of the pane, as the cutting and finishing processes cause a lot of imperfections to form on the glass edge.
One option to counteract the low level of edge stability is to use single-pane safety glass. In principle, the thermal pre-treatment generally guarantees a high degree of edge stability, however, this is much more costly from an economic perspective. In practice, there is a general assumption that processing the edges increases the quality of the surface, and therefore also improves edge stability. Studies have shown that the edge stability of the glazing available on the market are highly varied, regardless of the type of edge processing used. A well-cut edge from one manufacturer can have a higher level of edge stability than a ground glass edge from another manufacturer. We can assume that some manufacturers are able to avoid creating imperfections, meaning that the high edge quality with high edge stability can be reproduced in manufacturing.
The objective of the research project is both to manufacture float glass with a defined level of edge stability, and to develop a verified method for its assessment. This is intended to provide sound evidence for the glass edge, thereby offering economic advantages over single-pane security glass.
