Course Description: CEU Events: Fluid-Applied Air Barriers: Navigating Performance, Chemistry, and Environmental Limitations
Fluid applied air barriers do not all handle climate, moisture, and movement the same way, and much of the difference comes down to chemistry. Participants will compare and contrast common fluid applied membrane systems and examine the performance limitations of each. Testing standards and specification practices are also reviewed to help professionals select a system that keeps the air barrier continuous and protects buildings and occupants from air and moisture intrusion.
Understand the critical role of continuous air barrier design and proper field installation in protecting building envelope durability, preventing structural degradation, and safeguarding indoor air quality.
Compare chemical formulations (e.g., STPE vs. Acrylics) of fluid-applied Air & Water-Resistive Barriers (AWB) to evaluate application limitations, chemical compatibility, off-gassing, and long-term durability.
Analyze key industry testing standards (including ASTM E2178 for materials, ASTM E2357 for assemblies, and ASTM E779/E3158 for whole-building airtightness) to verify code compliance and resistance to wind pressures.
Develop a working knowledge of design and specification guidelines to set performance requirements for wall systems.
