All Glenny Glass Insulated products are certified by the Insulated Glass Certification Council (I.G.C.C.)
The Insulating Glass Certification Council (IGCC) is a non-profit organization jointly established 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 laboratory tests, per (ASTM) specifications, and unannounced plant quality audits and inspections assure the quality and performance of sealed insulated glass products.
