WHY IS IGCC SO IMPORTANT? The insulating Glass Certification Council is a non-profit organization jointly established in 1977 by manufacturers, consumers, specifiers and others concerned with the quality and performance of insulating glass units. IGCC sponsors and directs an independent, true third-party certification program. Periodic accelerated laboratory tests per American Society for Testing Materials (ASTM) Specifications and unannounced plant quality audits and inspections assure the quality of sealed insulating glass products.
