Webinar - Water Vapor Control for Walls with Continuous Insulation

Water vapor control is one of the trickiest and most risky areas of building and energy code compliance. The old “rules of thumb” no longer work reliably or universally. This session will engage participants with actionable design and construction guidance for integrated insulation and vapor control strategies using continuous insulation on wood- and steel-framed wall assemblies. It will relate vapor control with other moisture control strategies for moist air leakage and rainwater intrusion. Also featured will be a live demonstration of an online wall calculator tool to assist in optimizing code-compliant wall design for robust moisture and thermal performance.


Learning Objectives:
  1. Understand the three rules for moisture control that should never be broken.
  2. Learn five building science concepts for effective water vapor control.
  3. Know current building code requirements for water vapor control and vapor retarders.
  4. Learn how to apply a simple and robust online wall calculator tool to evaluate code compliance for water vapor and thermal performance.
