Learning Objectives:

  1. Assess the differences between air- and water-resistive barriers and determine strategies for mitigating unwanted air and water infiltration and exfiltration.
  2. Explore traditional and innovative weather-resistant barriers, including mechanically attached sheet products, fluid-applied membranes, self-adhered sheet membranes, and integrated sheathing materials.
  3. Examine challenges project teams may encounter with different types of weather-resistant barriers.
  4. Identify important specification and installation considerations for weather-resistant barriers.

In this course, we’ll talk about solutions for one of the primary concerns of designers and contractors—mitigating the intrusion of water and air through a structure. We’ll also assess the differences between traditional air- and water-resistive barriers and compare them to newer technologies, which can help specifiers choose the best WRB/AB for their projects to avoid moisture-related issues.
