Mitigating the intrusion of water and air through a structure is a primary concern for designers and contractors. By assessing the differences between traditional air- and water-resistive barriers and comparing them to newer technologies, specifiers can better avoid issues that lead to moisture concerns. Being aware of challenges to jobsite conditions and installation will further enable specifiers to choose the best weather-resistant barrier solution for their project’s building type.

Learning Objectives

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

Pre-requisite: Basic knowledge of water resistive barriers.
