Advanced Barrier Systems Design Seminar (ADSN) Thermal bridging through metal studs can undermine even well-insulated barrier assemblies—a concept the ADSN exam explores deeply. Before engaging this seminar, grasp how vapor permeability ratings interact with climate zones, and review the physics of air leakage paths in complex building geometries. Foundation in building science terminology and familiarity with current code compliance frameworks will sharpen your exam performance considerably.
