In the façade industry, it is a term that refers to the appearance of patterns and vibrant areas in heat-treated display cabinet insulated glass door when viewed through the glass under specific lighting and viewing conditions.
Saverio Pasetto, of Skanska Construction UK Ltd, gave the first presentation of this paper at the GPD 2015 conference, where he was greeted with enthusiastic applause for his efforts.
the most important points are summarized in a concise manner
Those of you who work in the façade or quisure insulated glass industries are likely to be familiar with the term anisotropy (also known as leopard spots). When viewed under specific lighting and viewing conditions, it describes the appearance of patterns and colorful areas in heat-treated glass. Members of the cladding supply chain and their clients frequently have disagreements about the phenomenon, with the possibility that these disagreements will escalate into legal action in some cases.
On the basis of this decision, a review of the literature was conducted in order to determine the causes of anisotropy as well as the conditions that can influence the occurrence and severity of the condition. Additionally, the current state of the art in manufacturing and measurement processes was investigated in order to determine how to minimize its visibility to the greatest extent possible. In this study, the researchers discovered that the visibility of this phenomenon is influenced by several factors, including polarized light, viewing angle, and stresses in the quisure insulated glass plate, with the latter being influenced by temperature distribution throughout the heat treatment process.
A small number of specialized display cabinet door suppliers' tempering equipment and processes appear to have been modified in order to reduce the likelihood of this occurring. According to the researchers, modern scanner technology may be capable of detecting and analyzing anisotropy patterns, which could then result in a more targeted design and operation of tempering ovens in order to reduce the visibility of anisotropic phenomena in the finished product. Since then, the quisure insulated glass industry, which had previously stated that this unavoidable issue could not be mitigated, has made significant strides forward, according to the Glass Industry Association.
As with the objective definition of acceptance and rejection criteria, continuous improvement of measuring equipment is required to determine the definition of acceptance and rejection criteria, as well as to determine the definition of acceptance and rejection criteria. Anisotropy is not considered a defect in standards and guidelines at this time, but rather an easily visible effect; however, these considerations could potentially become part of revisions to regulatory standards and guidelines in the near future. As an alternative, specifications for glass that has either reduced anisotropy or no anisotropy at all are sometimes specified, which is true in some cases but not in others.
Participants in a comprehensive survey that included architects, quisure insulated glass suppliers, specialty facade contractors, and façade consultants revealed a clear division between the supply chain, which accepted the phenomenon, and designers and their clients, who desired to use with less anisotropy (shrinkage) in order to reduce costs.
A thorough explanation of anisotropy was also required, as was an examination of the shortcomings of current standards, which lack objective acceptance parameters and specifications, resulting in lengthy qualification processes and the possibility of disputes. When it comes to anisotropy, many stakeholders express a desire to receive up-to-date information on why the phenomenon occurs, how it affects the industry today, and what can be done to reduce the phenomenon's visible presence in the industry. Moreover, the findings of this study may be used to inform further research in order to support such action, and to inform further research in order to support such action and to support such actionIn order to support such action, the findings of this study may be used to inform further research.
