Constructing Exterior Walls to Avoid Moisture Issues
Course #: HEN-WPR105-26
1 AIA LU/HSW
Explore the evolution of exterior wall systems, defines key components such as air barriers, water-resistive barriers, and vapor retarders, and explains the critical role of continuity in preventing moisture-related failures. Participants will review air barrier system types, performance standards (ASTM, IECC, IBC), and code requirements, while gaining practical insight into material selection, system compatibility,and installation considerations. The course emphasizes how proper design and integration of envelope systems improves durability, energy efficiency, and indoor air quality.
Learning Objectives
- Distinguish Air Barriers, water-resistive barriers and vapor retarders.
- Understand exterior wall evolution.
- Explain why continuity matters.
- Compare air barrier system options and Review applicable code requirements.
