Certified Insulating Glass Manufacturer (IGMA) Sealed unit assembly requires understanding how moisture infiltration degrades thermal performance and structural integrity over time. Candidates benefit from prior exposure to glazing materials, sealant chemistry, and the relationship between edge-of-glass temperatures and condensation risk. Familiarity with industry standards—particularly ASTM E773 and E774—proves invaluable when interpreting test data and manufacturing tolerances.
