Wall assembly components such as CI and WRBs are now required across the country, requiring in-depth understanding of wall systems. Improper design of transition details can lead to detrimental and expensive issues in wall assemblies. This course reviews building science fundamentals for complete wall systems with CI and WRBs, important considerations when designing transitions and penetrations, and common issues that arise from errors in sequencing, material compatibility and design verification.

Learning Objectives

  • Understand the performance of the wall components: air layer, water layer and insulation.
  • Examine the different types of details: penetrations, terminations and transitions.
  • Identify common installation and detail problems that occur on the jobsite.
  • Describe the assignment of contractor responsibility for installation sequencing of the various layers.
