Modern façade glass elements need to meet high and repeatable standards of security performance, as well as being acceptable for human physical and psychological comfort. New standards and philosophies on protective glazing have emerged with the publication of two very significant international standards involving ballistic assault. Those standards and laminated glass configurations or design methodologies will be explored. This paper will outline the significant portions of those standards that influence glazing selection and examine how these performance characteristics are able to be multifunctional to meet other requirements such as safety, acoustic, solar, thermal and structural with style.
