Presented by Laura Bashaw

Learning Objectives:

  1. Learn the types of air barriers and why they are specified.
  2. Understand industry standards that address fluid applied air barriers.
  3. Learn why air- and water-resistive barriers are a critical competent in the wall assembly.
  4. Understand research testing results and their impacts on the durability of fluid applied air barriers.



Laura Bashaw will present on SGH’s experience to date with fluid applied air barrier membranes, focusing on SGH’s self-funded research. Fluid applied air barrier/water-resistive barrier membranes for use in exterior wall systems are increasingly specified by designers. Because these products are relatively new, their long-term performance is not well established. They have also been observed failing in the field during construction. Laura will discuss the status of industry standards, results of internal testing and identification of important performance characteristics.
