Atmospheric Effects on Insulating Glass Units (AEIGU) analyses insulating glass (IG) units constructed in one environment and transported to another. Combinations of changes in elevation, temperature, and barometric pressure create loads on IG units. Some loads are temporary such as those resulting from elevation changes during transportation as well as variations in temperature and barometric pressure. Other loads can be permanent such as final installation at a different elevation than manufacture. AEIGU uses finite difference analysis, parameters consistent with those in ASTM E 1300–07, “Standard Procedure to Determine the Load Resistance of Glass in Buildings” and load sharing computations to determine stresses in glass lites in IG units and, where applicable, probabilities of breakage consistent with ASTM E 1300-07. AEIGU addresses load duration and glass in-service life in its computations.
The below table describes the features of the Atmospheric Effects on Insulating Glass Units program.
