Fluid-Applied Air & Water Resistive Barriers: A Practical Comparison


Fluid applied air and water resistive barriers are quickly gaining professional and market acceptance, supplanting traditional sheet based barrier systems. Many manufacturers have entered this growing market. However, contrary to initial impressions, there are significant differences between competing products, which are rooted in each product’s particular chemistry. These differences affect substrate compatibility, re-emulsification risk, UV exposure, application procedures, accessory requirements, and fire safety. Before the AEC industry embraces fluid applied systems generically as a panacea for resolving all air and moisture intrusion issues, persons responsible for the design and construction of effective building enclosures need understand the critical differences within the spectrum of products sold as fluid applied barriers.

Our presenter, Dave Kimball, will begin the program with a thorough discussion of fluid applied air and water restive barrier systems and then conclude with a hands-on demonstration of some of these products.

Learning Objectives

  • Discuss the history of fluid applied air and water barrier systems, including technical development and market introduction.
  • Gain an overview of different fluid applied systems available in the marketplace, including Building Code considerations and comparisons to more traditional sheet based barrier systems.
  • Compare advantages and disadvantages of different chemical formulations used in fluid applied systems, including re-emulsification risks, reinforcement requirements, substrate compatibility, and fire safety considerations.
  • Develop critical awareness of options available for fluid applied air and water barrier systems and apply it to making project appropriate selections.

About Our Presenter

Dave Kimball is a Technical Specialist in the Building Envelope Group at Prosoco, Inc., covering the North Atlantic Region from his office in Long Island City, NY. Kimball has consulted on such high-profile projects as the Pentagon, Wash. D.C.; the Transamerica Pyramid, San Francisco; and the One World Trade Center, New York City. With areas of expertise in weatherseal, structural glazing, and exterior coatings applications, he now focuses on the unique challenges presented by rough opening preparation and air and vapor barriers. Kimball received a BS in Chemistry and General Business from Saginaw State University. He began his professional career at Dow Corning as a chemist in 1979. In 1988 he moved to the field as a technical specialist, working all over the US. After 34 years at Dow Corning he moved to Prosoco in 2013. Along with belonging to the Sealant Waterproofing and Restoration (SWR) Institute, Kimball is also a member of standards testing organization ASTM International.
