Webinar: Wind-driven Rain, Windows, and Walls with Continuous Insulation

Description:
Rainwater intrusion is one of the most important durability concerns for buildings and building enclosures. For walls, it is mainly a concern when there is coincidental wind and rain, i.e., wind-driven rain. Wind creates pressure differentials that drive water through small holes and cracks, through fenestration seals, around unsealed lap joints in water-resistive barriers, and over or around mechanical flashing. It is important that walls are robust against the wind-driven rain hazard, as it varies across the U.S. This session will focus on the latest research and code provisions related to the use of foam sheathing continuous insulation as WRB systems and integration with flanged fenestration for water resistance and structural support and anchorage. Use of properly detailed foam sheathing around window openings to minimize thermal bridging will also be addressed. Finally, preliminary findings from climate research to map the U.S. wind-driven rain hazard will be presented along with observations relevant to building envelope design to resist rainwater intrusion

 

Learning Objectives:
  1. Understand the three rules for moisture control that should never be broken.
  2. Learn about recent building code improvements to help prevent rainwater intrusion while maximizing benefits of newer energy conservation codes and minimizing thermal bridging.
  3. Apply lessons learned from field experience and recent research regarding installation and performance of windows installed in walls with foam plastic insulating sheathing.
  4. Learn how new research will provide design insight and guidance for addressing the wind-driven rain hazard, as it varies across the U.S.
