Thermal Glass (NFRC) NFRC certification assumes you’re already comfortable reading U-factor ratings, solar heat gain coefficients, and condensation resistance metrics—the core language of window and door performance. Candidates often arrive with experience in building science, HVAC principles, or glazing installation. Entering without this foundation leaves gaps when assessments shift toward thermal bridge analysis and frame-to-glass heat transfer dynamics.
