Drywall Environmental Impact (GBCI) Drywall selection and installation directly influence indoor air quality, moisture management, and long-term structural integrity. The GBCI exam covers fire-rated assemblies, mold-resistant core materials, and low-VOC finishing compounds—knowledge that prevents costly remediation and warranty claims. Professionals who grasp these distinctions reduce callbacks and build client trust through informed material choices.
