Water, Wind, Windows, and Walls with Continuous Insulation
October 27, 2022 @ 1:00 PM - 2:00 PM EDT
In this session we will explore new research and resources in support of an integrated and risk-consistent approach toward the design and evaluation of water-resistant exterior wall assemblies. First, some foundational principles of moisture management are reviewed with actionable resources to implement those principles. Along the way, we will also identify a crucial missing link, namely, a rational quantification of the wind-driven rain climate hazard as it varies across the U.S. New wind-driven rain climate research will be presented with a view toward the eventual development of risk-consistent performance criteria for the evaluation of wall assembly water-resistance using existing test methodologies like ASTM E331. Finally, we’ll review the results of a comprehensive research effort that evaluated the durability, structural, and water resistance performance of fenestration installations on various frame wall configurations with and without continuous insulation. From that research, an actionable installation accepted practice guideline was developed for use on walls where foam plastic insulating sheathing is used as both the WRB and continuous insulation.
- Learn 5 concepts and 3 rules that are the foundational principles of any integrated approach to moisture control, including actionable resources to implement them.
- Gain insight into wind-driven rain and new climate research quantifying it as a hazard in metrics that can be used to establish performance criteria for risk-consistent design of building envelopes.
- Appreciate the variation in wind-driven rain hazard across the U.S. and how it might affect appropriate criteria for evaluation of wall assemblies and components using test methods like ASTM E331.
- Understand the latest research on fenestration installation performance for durable structural and water-resistant installation practices for use on frame walls with foam plastic insulating sheathing continuous insulation.
