Water and moisture intrusion can affect everything from a building’s structural durability to its indoor air quality. Understanding the material options, installation, and testing criteria for high-performing weather-resistant barriers can help specifiers manage present and future moisture concerns.

Learning Objectives

  • Examine the effects of moisture intrusion on building durability, thermal efficiency, and health and indoor air quality.
  • Analyze the ways in which weather- and air-resistant barrier selection and installation affect moisture management and the building envelope.
  • Explore testing criteria for high-performing weather-resistant barriers.
  • Evaluate the importance of surfactant resistance, draining bulk water, and proper installation of weather-resistive barriers.

Prerequisite Knowledge For the Course: Basic knowledge of weather-resistant barriers.
