This article originally appeared on M. Stephen Doggett, PHD’s LinkedIn page. Yesterday I presented at the SeaBEC annual symposium. It was a great event at a wonderful venue with some awesome people in attendance. I would like to thank the event organizers, SeaBEC members, attendees, and vendors. Great job! In my presentation “Dynamic Interfaces of Water-Resistive Barriers”, I discussed three important interfaces concerning framed wall construction with exterior insulation and inboard WRBs: 1) The Insulation Interface; 2) The Substrate Interface; and 3) The Fastener Interface. Much information was discussed, but I would like to reiterate my closing remarks. As we embrace this new paradigm, we must recognize that product test methods lack relevance and meaningful insight into actual in-service performance. We currently rely on drainage efficiency test methods (ASTM E2273) that do not represent actual drainage. We rely on water-resistance test methods (AATCC 127) that do not represent actual water resistance. And we rely on fastener sealability test methods (ASTM D1970) that do not represent actual sealability. We are left with the need to independently validate WRB performance on the basis of more practical, real-world scenarios with real-world WRB interfaces. Without this change, we can anticipate a new era of building enclosure failures. About M. Steven Doggett, PHD We at Performance Pro Supply are big fans of the work of M.
