October 29, 2020 @ 1:00 PM - 2:00 PM EDT

Live webinar sponsored by the Air Barrier Association of America


Don’t Lose Your R Over the Z

Presented by Chip Bisignaro


This course defines and explains building science behind the code for the four control layers of the building envelope: water, air, thermal, and vapor. Participants will then explore typical design principles as well as alternative system assembly approaches to exterior wall design.

In addition, presentation covers common attachment strategies for various types of claddings, including masonry, rainscreen veneers, and applied/adhered veneers.



Learning Objectives:


  1. Participants will learn the definitions, code, and building science for the water, air, thermal, and vapor control layers.
  2. Participants will learn principles behind typical design of control layers in exterior wall for water, air, thermal, vapor.
  3. Participants will explore wall system assembly design approach to exterior wall design to successfully maintain 4 control layers (water,
    air, thermal, vapor).
  4. Participants will understand attachment strategies and building science considerations for masonry, rainscreen veneers, and applied/
    adhered veneers
