The use of incompatible glazing components can result in premature insulating glass (IG) failure. This presentation explains the processes which occur during the interaction of the components used in insulating glass and glazing. These interactions can cause material property changes, where components are no longer able to fulfill their function within a system. Lack of compatibility can cause a wide variety of very different failure modes and requiring the need for careful analysis. Origins and mechanisms of loss of function as a result of lack of compatibility are mainly related to diffusion processes, which change material properties in bulk and surfaces. Based on a solid knowledge of materials and available test methods, risks can be assessed and compared for different solutions. Modification of systems can avoid risk by reduced material contact wherever acceptable control of building construction can be ensured. Based on understanding of critical processes, a new generation of materials is presented which avoid risks due to influence of contact materials.
