(NGA) Certified Glass and Glazing Specialist (CGGS) After earning CGGS, specialists apply their knowledge daily—inspecting thermal performance of commercial facades, troubleshooting failed seals in curtain walls, and certifying compliance with building codes. Glass and glazing contractors rely on CGGS holders to evaluate energy efficiency metrics and recommend cost-effective upgrades. In renovation projects, your credential becomes the reference point for clients deciding between laminated, tempered, or low-emissivity options, directly influencing material selection and project budgets.
