Certified Glass Systems Fabricator and Installer (NGA) Tempered glass behaves radically differently from annealed stock during cutting and edging—a mistake here cascades through your entire installation sequence. Incoming candidates should understand load calculations for structural glazing, the physics behind thermal stress, and why improper edge treatment fails catastrophically. Familiarity with building codes, safety protocols, and precision measurement is non-negotiable. The NGA exam assumes you’ve spent significant time on job sites seeing how environmental factors, frame compatibility, and installation sequencing interact in real buildings.
