Part I:
July 20, 2010 
1 - 2 p.m. (EDT)

Part I will provide an overview of the moisture transport mechanisms in exterior walls and roofs; followed by a discussion of the similarities and differences in air barriers vs. weather-resistive barriers vs. vapor retarders.  The benefits of air barriers in improving energy efficiency will also be discussed. 

• Understand bulk water and water vapor migration mechanisms in exterior walls
• Understand the relative severity of various moisture migration mechanisms
• Understand how to prevent bulk water, water vapor transmission through permeance, and water vapor transmission through air movement
• Review the performance characteristics of commonly available vapor retarders, weather-resistive barriers and air barriers
• Understand the impact of air barriers on energy use in buildings

Part II:
July 27, 2010 
1 - 2 p.m. (EDT)

Part II will focus on utilizing information presented in Part One when designing exterior walls.  The panelists will discuss typical wall assemblies and illustrate use of a simple qualitative analysis of wall performance that can help select and position the most appropriate air barrier, weather-resistive barrier and/or vapor retarder.  The webinar will conclude with a discussion of a wall assembly that eliminates moisture accumulation within the wall in all climate conditions (the "work everywhere wall assembly").

• Understand how to predict moisture accumulation and transport through a wall assembly
• Understand how various moisture migration mechanisms affect typical wall assemblies
• Understand how placement of vapor retarders, weather-resistive barriers and air barriers within a wall assembly can impact the wall performance
• Become familiar with the "work everywhere wall assembly"
