Description

Building enclosure design typically addresses the need for an exterior wall to be able to drain and dry moisture that is present throughout the year. Depending on the cladding system, this may be difficult to achieve using current practices, and may warrant the decision to include a designed drainage space, or a rainscreen, in the wall assembly. This webinar will discuss the benefits of rainscreen systems, the products available to create this designed space, and the best practices for integrating rainscreens into the overall assembly.

Learning Objectives

1. Analyze the sources of moisture on exterior wall assemblies and the impact that moisture has on the durability of the overall system.
2. Understand the material and product options available in order to create a rainscreen gap behind exterior cladding as well as cost implications of these systems.
3. Discuss existing code requirements related to exterior moisture management and how rainscreen gaps fit into these provisions in order to provide a safe and sustainable assembly.
4. Examine the impact of rainscreen systems on specific cladding types as well as the potential for failure of certain claddings without robust moisture management details.
