Advanced Glass and Glazing (NGA) The NGA exam digs into thermal properties, structural glazing systems, and weatherproofing—knowledge that directly prevents costly failures on real projects. A glazier who understands U-values and sealant compatibility avoids callbacks and warranty disputes. You’ll face questions rooted in building code compliance and material selection that separate professionals who can troubleshoot installation problems from those who merely follow specs.
