Weather barriers have long been understood as essential to construction projects to provide resistance to air and water. New technologies for weather-resistant barriers (WRBs) that allow for more water drainage, better air flow and resistance to UV, moisture and other weather-induced issues have been successfully tested. This course looks at the evolution of barriers and provides in-depth discussion of the latest barrier systems, their testing methods and the outcomes, which include better sustainability and higher levels of occupant comfort, health and safety.
By the end of this course, you will be able to:
- Describe how 360-degree drainage barrier technology promotes durability and sustainability by improving the building envelope.
- List five tests for which these new barrier technologies have successfully met standards.
- Explain how better air barriers lead to occupant health and sustainability.
- Discuss the issue of surfactants and how new barrier technology avoids them, offering a more sustainable project and better occupant health and well-being.
