The National Glass Association’s Glass Conference in Ann Arbor, Michigan, brought together industry professionals for technical sessions, presentations, and networking focused on the latest in glass performance and regulation.
Bill Lingnell, an industry consultant, shared insights on glazing failures and glass breakage. Examining fracture patterns in annealed glass, he highlighted common causes such as thermal stress, impacts, scratches, and improper glass-to-metal contact. While nickel sulfide inclusions are often blamed for spontaneous breakage, Lingnell emphasized the need for testing and careful analysis rather than assumptions. He urged engineers to replicate field conditions and ensure code compliance to prevent long-term failures.
Vaughan Schauss of Kuraray discussed ASTM E3401, a 2024 standard for laminated glass under hydrostatic loads, relevant for swimming pools and aquariums. Schauss stressed compatibility with sealants, metals, and exposed edges, and noted emergency planning for both humans and animals if glass fails.
Consultant Tom Culp updated attendees on energy codes, noting a shift toward local regulations and continued advancement of ASHRAE 90.1 and the IECC. He highlighted regional initiatives like Colorado’s Energy Star requirements and Boston’s net-zero zoning policies. 
Participants also toured Guardian Glass’s Technology and Development Center and Carleton float plant, exploring R&D processes and seeing various glass types in a mock-up façade.
