Learning Objectives:

  1. Define vented rainscreen design and its historical development.
  2. Identify the benefits and components of vented, vapor-open WRB/AB wall assemblies.
  3. Recognize the benefits of highly vapor-permeable WRB membranes and compare the differences between vapor-tight WRB membranes.
  4. Describe the design details for a vented rainscreen system.

Studies show that a vented rainscreen assembly has the ability to:

  • Effectively drain water that has entered the behind the cladding
  • Reduce the wet time of absorptive claddings
  • Increase drying of the interstitial wall assembly
  • Mitigate reverse vapor drive for highly permeable water-resistant barrier/air barrier (WRB/AB) systems

This course investigates current knowledge of vapor-open (permeable) WRB/AB and vented rainscreen cladding wall assemblies and their ability to mitigate water intrusion, thereby reducing long-term exposure and enhancing the drying capacity of the building assembly providing a healthy and extended life of the building.
