David Cooper has been researching and developing vacuum insulating glass for over a decade and chairs multiple international standards committees that will define how it can be used, how its quality can be assessed and how to test its performance. With demand for VIG growing and producers multiplying, specifiers and contractors need guidance on what to look for in these products – guidance that may be coming soon in the form of balloted ASTM standards for durability and load tolerance. Cooper joins The Conversation to explain where these efforts are at and to update us on the state of VIG technology and availability.
