Introduction to Weather Resistant Barriers
A building science primer
Sponsored by TYPAR | Presented by Daniel Overbey, AIA, LEED Fellow
Webinar On-Demand
This course will offer attendees a building science primer into envelope control layers. The webinar will describe the ways in which heat and moisture interact and move through building envelope assemblies. Next, the session will outline the essential barrier functions of the building envelope and introduce the concept of weather resistant barriers (WRBs). After introducing some common types of WRB products, the webinar will address common misconceptions about envelope control layers. The session will conclude by addressing basic code considerations with regard to WRBs and describing the potential value proposition of building envelope commissioning to better ensure WRBs are applied correctly and effectively.
